2010 – giatec is established and starts offering iot solutions to the concrete industry . this same year the burj khalifa in dubai sets the new record for tallest structure built with reinforced concrete . it stands at an impressive 2 , 717 ft . tall .
where : m ( t ) is the maturity index at age t ; t a is the average temperature during time interval ∆t ; t 0 is the datum temperature . astm c1074 provides a standard procedure to find the datum temperature for a specific mix design . however , most of previous studies suggest a practical estimation of the datum temperature that is between 0 °c and - 10 °c . indeed , this is the temperature at which the hydration of cementitious paste stops ; hence the strength development of concrete ceases . unpublished results by giatec scientific inc . show that this temperature resides within an interval between 0 °c and - 5 °c dependent on the concrete mix design . <
giatec has also developed advanced non - destructive testing ( ndt ) technologies for the durability - based performance analysis of concrete materials and the accurate condition assessment of infrastructure . these products help engineers manage civil infrastructure by allowing them to schedule maintenance , rehabilitation and replacement operations more efficiently .
traditionally , construction firms have been able to accomplish much of what giatec is offering by running wires into the concrete and then using a reader to take measurements from inside the concrete . but wires can be a hassle as they are often pulled out accidentally or tripped over by construction workers .
using bluetooth technology , the sensor then communicates with giatec’s ios or android app , sending various readings , including internal temperature as the concrete cools . the sensor battery lasts for about two months , more than long enough for companies to determine when the concrete is set and address any temperature problems .
at giatec , our core values are creativity , passion , and integrity . we have created a solid company culture based on these values , which are integral to all of our activities , including hiring , r & d ; , engineering , production , marketing , sales , and technical support .
alizadeh said he believes giatec will sell at least 16 , 000 of the tiny sensors next year . he plans to manufacture the devices in ottawa until order volumes hit at least 100 , 000 units annually , when he will need to look overseas . the company employs 12 people locally and is privately funded .
“we haven’t even put this on the website yet , ” said alizadeh , adding that on top of the city of ottawa , which uses five giatec sensors for every 15 metres of concrete poured in the new lrt tunnel , builders from as far away as chicago have already put his firm’s sensors to work in construction .
“the giatec smartrock device is the next wave in concrete maturity technology . this new and cutting edge concept puts quality control and quality assurance back into the hands of the concrete manufacturer and for the first - time ever , in the hands of the contractor . operating the smartrock sensor is intuitive and the confidence it provides is priceless . ”

a young ottawa company has developed — and is getting solid reviews for — a loonie - size wireless sensor that can be buried deep in concrete and allows builders to monitor the condition of the concrete as it cures .
to most people , concrete doesn’t warrant a second thought . it’s everywhere : basements , bridges , sidewalks , walls and planter boxes .
it’s been in use for thousands of years but , as it turns out , it’s not as easy to work with as many would assume . in fact , it’s incredibly finicky stuff .
but a young ottawa company has developed — and is getting solid reviews for — a loonie - size wireless sensor called smartrock that can be buried deep in concrete and allows builders to monitor the condition of the concrete as it cures .
which started out with a handheld scanner that could determine the condition of concrete structures .
“we’ve shifted focus to our sensors . we see this huge potential to ramp up sales for sensors . ”
because concrete cannot dissipate heat very quickly , alizadeh explained , “the internal temperature can go as high as 60 degrees celsius … if it goes beyond that level there is internal cracking ( and ) damage . ”
on top of that , it can be a crapshoot to determine when concrete is ready to be removed from its forms .
“if they open the formwork too early , the concrete cracks and collapses . if they open it too late , it’s a financial burden , ” alizadeh said .
waiting too long gives the concrete time to stick to the forms , making them impossible to remove in a single piece . as a result , the forms have to be ripped off , which destroys the forms and can damage the concrete underneath .
as concrete structures get bigger and are placed in unusual locations , including underneath the rideau canal , the need to ensure that the concrete is set properly and without any structural deficiencies is becoming critical for builders , meaning alizadeh’s firm finds itself flooded with inquiries .
the introduction of the sensors in concrete is the first step to having truly “smart concrete” buildings in the near future , said alizadeh . as the sensors become more complex , they could one day send back other metrics such as structural deficiencies or even decay from within the walls or floors .

in toronto , chunks of concrete seemed to be falling off the 60 - year - old gardiner expressway every week this summer .
in montreal , many of the concrete structures that went up in the heady days before expo ‘67 are crumbling , including the turcot interchange and the aging mercier and champlain bridges .
and just this week , it was announced that an inquiry into the deadly mall collapse in the northern ontario community of elliot lake last june is likely to begin in early 2013 .
all over this country , structures that opened with great pomp and fanfare decades ago are becoming headaches and eyesores as they age and fall apart , potentially endangering the lives of the residents who’ve come to rely on them .
those are the questions that structural engineers are asked every day . but it seems there are few clear answers .
samir chidiac , an expert on structural materials and a professor of civil engineering at mcmaster university in hamilton , ont . , says it’s often a near - impossible task to try to determine the lifespan of a concrete structure , because there are simply so many factors to consider .
“in canada , we know there are two main things that damage concrete structures : we have freeze - thaw , and we have road salt , which leads to corrosion . these are the two main elements that lead to deterioration , ” he says .
as every canadian who has ever driven over a pothole knows , water has a way of seeping into roadways and concrete . and when it does , it expands as it freezes , then shrinks again when it thaws , causing cracks .
water mixed with road salt can rust a bridge’s rebars - - the reinforcing bars that strengthen the concrete – which then warp , causing more cracks .
if not tended to in time , that salt and water will eventually make its way to the steel beams that hold the structure up , risking the kind of horrific collapse seen in laval , que . , when a 2006 overpass collapse killed five .
it doesn’t help that summer’s high temperatures take their own toll on concrete . and increased vehicle traffic puts further weight on bridges , accelerating their demise .
it’s up to structural engineers to decide when a bridge or overpass has reached the end of its lifespan . and to do so , they turn to a number of technologies to evaluate how a structure’s concrete is resisting all the forces against it .
engineers can do core testing to extract a large cylinder sample of concrete and evaluate its residual strength , or to see whether salt is causing it to break up .
but because such tests destroy a small section of the structure , engineers prefer to do tests from the outside , using methods with such names as ground - penetrating radar , thermography , and pulse velocity tests . there’s also impact - echo testing , which sometimes involves dragging chains across a structure to listen for hollow sounds and spot internal crumbling .
“the technique isn’t actually new . what’s clever is the portable system they developed , ” says chidiac .
all these tests can evaluate only local spots ; they can’t assess the integrity of the structure as a whole . nor are they predictive : no one test can tell inspectors how much longer a structure can stand .
“so what we end up doing is using as many of these tests as possible to try to understand what’s happening inside the structure , ” says chidiac . “we look at all the results in relation to each other .
“sometimes they give us good information , sometimes they don’t . that’s why it’s difficult for engineers to assess the structure in a conclusive way . ”
so if it’s so difficult to predict the lifespan of concrete , why do we keep using the stuff ? the simple answer : it’s cheap and it works .
“cement and concrete are not going anywhere . they are still the most economical material , ” says chidiac . “and they can be formed into any shape . concrete can also be made on site . that’s why it’s the number one construction material worldwide . ”
engineers have experimented with other materials and polymers . a number of bridges have gone up in recent years made of frb , or fibre - reinforced plastic , for example . but such materials are very expensive , says chidiac , and come with their own problems .
the good news is that the technology is improving , thanks to the use of finer particles and the addition of supplementary materials that can strengthen it .
but nothing , he says , will stop the forces of nature from working to destroy concrete .
“there’s no such thing as foolproof material ; they are all engineered materials and that means they want to resort back to their original state , ” says chidiac . “the best approach is simply to assume that something is going to go wrong and mitigate that . ”

there is no denying that concrete and the technology surrounding it has come a long way since its discovery and development . from the great pyramids at giza to smart sensors for testing concrete temperature , maturity , etc . , we’ve put together a list of notable events and discoveries in the history of concrete .
6500bc – uae : the earliest recordings of concrete structures date back to 6500bc by the nabataea traders in regions of syria and jordan . they created concrete floors , housing structures , and underground cisterns .
3000 bc – egypt and china : egyptians used mud mixed with straw to bind dried bricks . they also used gypsum mortars and mortars of lime in the pyramids . the great pyramids at giza used about 500 , 000 tons of mortar . a form of cement was also used to build the great wall of china around this time .
600 bc – rome : although the ancient romans weren’t the first to create concrete , they were first to utilize this material widespread . by 200 bc , the romans successfully implemented the use of concrete in the majority of their construction . they used a mixture of volcanic ash , lime , and seawater to form the mix . they then packed the mix into wooden forms , and once hardened , stacked the blocks like brick . after more than 2 , 000 years , roman concrete structures stand tall due to their ingredients colliding with earth’s natural chemistry .
technological milestones : during the middle ages , concrete technology crept backward . after the fall of the roman empire in 476 ad , the technique for making pozzolan cement was lost until the discovery of manuscripts describing it was found in 1414 . this rekindled interest in building with concrete .
1793 – it wasn’t until 1793 that the technology took a big leap forward when john smeaton discovered a more modern method for producing hydraulic lime for cement . he used limestone containing clay that was fired until it turned into clinker , which was then ground into powder . he used this material in the historic rebuilding of the eddystone lighthouse in cornwall , england .
1824 – joseph aspdin invented portland cement by burning finely ground chalk and clay until the carbon dioxide was removed . aspdin named the cement after the high - quality building stones quarried in portland , england .
19th century – concrete was used mainly for industrial buildings . the first widespread use of portland cement in home construction was in england and france between 1850 and 1880 by francois coignet , who added steel rods to prevent exterior walls from spreading .
1830 – lime and hydraulic cement is produced for the first time in canada .
1854 - the first home constructed using reinforced concrete was built in england by william wilkinson . the first reinforced concrete home in the u . s . was built in 1875 by william ward . this is said to be the start of what is now a $ 35 billion industry in america .
1891 – george bartholomew poured the first concrete street in the u . s . , and it still exists today . the concrete used for this street tested at about 8 , 000 psi , which is about twice the strength of modern concrete used today .
1902 – august perret designed and built an apartment building in paris using steel - reinforced concrete for the columns , beams , and floor slabs . concrete became more socially acceptable as the building featured an elegant façade .
1904 – the first concrete high - rise building , the ingalls building , was constructed in cincinnati , ohio . it stands 16 stories tall .
1913 – the first ready - mix load was delivered in baltimore , maryland . four years later , the national bureau of standards and the american society for testing and materials ( astm international ) established a standard formula for portland cement .
1930 – air entraining agents were developed that greatly increased concrete’s resistance to freezing and improved its workability . it was an important development in improving the durability of modern concrete . air entrainment is the use of agents that , when added to concrete during mixing , create many air bubbles that are extremely small and closely spaced , and most of them remain in the hardened concrete .
1936 – first large concrete dams , the hoover dam and the grand coulee dam were built and still exist today .
1967 – the assembly hall , the first concrete domed sport structure , was constructed at the university of illinois .
1970 – fiber reinforced concrete was introduced . fibrous material increases the concrete’s structural integrity . fibers can be made from polypropylene , nylon , steel , or blends of different materials . methods have also been developed to make use of recycled tires to create fiber reinforced concrete .
1985 – union plaza in seattle , washington was constructed using the “highest strength” concrete .
1990 – a new height record was set by 311s wacker drive in chicago . the reinforced concrete building stands at 920 ft .
1999 – polished concrete is introduced to the united states by htc . although the bellagio in las vegas is the first installation in the united states to see the polished concrete , its popularity quickly soared due to its pleasing aesthetics . today it is used in everything from stores to homes including floors and pieces of furniture .
2000 – the first standards and certification program for sustainable construction called leed is launched by the united states green building council . this sparked a new push toward green building and brought on new criteria for evaluating building materials and their performance .
2003 – the solaire , the first green residential high - rise building in the united states is built just blocks away from ground zero and sets new standards with new york building agencies .
2004 – creators add special fibers created by hungarian architect aron losonczi that transmit light in concrete to create translucent concrete .
2016 – the world’s first fully functional 3d printed building , the office of the future , is completed and celebrates its grand opening in dubai .
as technology evolves , it ' s no secret that concrete will continue its evolution . what will we see in the next 10 , 50 , or 100 years ?

such approaches to compressive strength evaluation may cause concrete contractors to make conservative decisions , face more complicated technical problem ( e . g . delay in formwork stripping , and unnecessary long - term curing and surface protection ) , and spend more financial resources .
this technical article describes how the maturity curve is developed , and how it is applied for on - site estimation of the compressive strength of concrete .
maturity method is a relatively simple approach for estimating the in - place compressive strength of concrete , specifically at early ages less than 14 days . once the maturity curve is developed in the laboratory for a specific project , it can be used for on - site estimation of compressive strength of concrete in real - time .
the maturity method is governed by the fundamental assumption that a given concrete mix design poured during course of a specific project has the same compressive strength when it has the same “maturity index” . it means that a given concrete mix design , for example , may reach the same compressive strength after 7 days of curing at 10 °c when it is cured at 25 °c for 3 days .
the maturity method based on the astm c1074 is the most commonly used method to estimate the in - situ strength of concrete . astm c1074 provides two maturity functions : 1 ) nurse - saul function ; and 2 ) arrhenius function . based on the nurse - saul method , there is a linear relationship between the maturity and the temperature in real time . the underlying assumption is that the strength development in concrete is a linear function of hydration temperature . equation 1 shows the relationship between maturity and hydration temperature history .
m ( t ) = ∑ [ ( t a - t 0 ) x∆t ] , eq . 1
the second approach is the arrhenius function that assumes there is an exponential relationship between the compressive strength and hydration temperature . the maturity index is defined in form of an equivalent age at a reference temperature . it means the actual age should be normalized to the reference temperature in order to estimate the compressive strength . this function needs a value of activation energy that can be determined as the procedure detailed in astm c1074 .
as detailed in astm c1074 , there is a step - by - step guide for developing the maturity curve , and for estimating the compressive strength . these steps are described as follows .
the maturity - strength curve represents the relationship between maturity index and compressive strength for a specific concrete mix design , adopted in the laboratory . to do so , adequate concrete cylindrical specimens should be casted , and then stored in the semi - adiabatic condition for curing . certain number of concrete cylinders ( i . e . at least two concrete specimens ) should be equipped by embedded temperature sensors for recording the hydration temperature history . the compressive strength of concrete is measured at ages of 1 , 3 , 7 , 14 and 28 days .
the maturity index is calculated at strength testing times using equation 1 . then the best curve will be fitted for the strength data versus maturity index data . it should be noted that it is important to test the concrete mix design that will be the same as that used in the construction project . any deviations from the original mix design ( such as water to cement ratio , cement content , etc . ) will reduce the accuracy of the maturity method to estimate the compressive strength .
once the maturity – strength curve is developed , it can be used to estimate the in - place concrete strength using the hydration temperature history . to do so , the temperature history of the concrete elements should be recorded after pouring using embedded sensors at the locations that are generally critical in term of exposure conditions , curing and structural requirement . routine quality control tests should be performed to ensure the accuracy of the maturity – strength curve . these controls minimize any error in the estimation of in - place strength due to inherent limitations of the maturity method .
in - place concrete is not representative of the concrete used to develop the calibration in the lab . this can be because of changes in materials , water to cement ration , air content , batching method , etc ;
using a datum temperature ( for the nurse - saul function ) that is not representative of the concrete mixture can result in incorrect estimation of strength .
several maturity devices have been developed that can measure the hydration temperature of concrete in real time . most of these devices such as flir intellirock , command center , and concure idrop can calculate maturity index and predict the compressive strength if the maturity – strength curve , datum temperature and any required information are developed . most of these devices include a temperature sensor embedded into the concrete elements that is plugged in the data logger via an electrical cable . alternatively , a simple thermocouple could be embedded in concrete for temperature monitoring using a connected data logger . the data should then be extracted and used to calculate the maturing index and use it to estimate the concrete strength from the maturity curve .

for mr . trump , doing things bigger than most has been a guiding principle , as reflected in his penchant for slapping his name on buildings and planes . in june 1989 he launched the trump shuttle , after paying $ 365 million to buy the old eastern airlines shuttle operations , which connected new york city with boston and washington . the deal is not counted among his more successful ventures . in 1990 he defaulted on his loan and lost control of the airline to a group of lenders . around the same time , a helicopter shuttle service he ran also fizzled .

mi - 8 helicopters during the joint russian - belarussian zapad 2017 military exercises on monday .
the video , from the online news portal urltoken , shows two helicopters swooping over a field at treetop level before one suddenly fires off rockets that seem to hit a truck just a few yards from the bystander , who was standing on the parking lot , which is next to a firing range near st . petersburg .
the misfire came during a major exercise , called zapad 2017 , or west 2017 , though the timing of the strike was unclear . the exercises began thursday and run through wednesday .
intended to flex russian military muscle along the border with nato countries to the west of russia , the exercises have also highlighted some safety lapses . already one russian soldier has died from a ricocheting tank shell .
“all reports on social media of salvos fired at a crowd of journalists and a large quantity of gravely injured people are intentional provocations , or somebody’s personal stupidity , ” the statement said . it did not clarify whether anyone was wounded in the misfire .
the news portal said an unidentified witness had provided the video , and suggested the mishap at the luzhsky firing range occurred either sunday or monday . a longer video posted by another news site , fontanka , shows civilian cars and a military truck damaged by shrapnel .
zapad 2017 is a revival of a soviet - era training maneuver that once included forces from the warsaw pact , the soviet military alliance whose members have now joined nato . today , only the armies of belarus and russia take part .
the exercises have raised fears in belarus that the kremlin intends to leave behind some of its forces , creating a permanent military presence there .
tensions are also high across the border , particularly in the baltic states , where defense planners recall that similar large scale war games were used as by russia to cover preparations for the invasion of crimea and the establishment of a separatist zone in eastern ukraine .

of all the things connected to donald j . trump , few have given him more mileage than his fleet of aircraft .
his boeing 757 jet , often referred to as trump force one , has received the full rich - and - famous lifestyle treatment ; the washington post even queried whether it was better than air force one .
one of mr . trump’s helicopters has gotten similar coverage ; an interior renovation made cnbc’s “secret lives of the super rich” in a segment entitled “pimp my chopper . ”
a close look at mr . trump’s two airplanes — the 757 and a smaller jet used on the campaign trail — and three helicopters , however , suggests that their value rests chiefly in their marketing potential , with the trump stamp of status masking the fleet’s age .
most people who own aircraft do not have more than one or two . even those who can afford to own planes often lease or charter them instead , offering a layer of ease and anonymity . but anonymity is not mr . trump’s style . the boeing , built in 1991 to seat roughly 200 people , is mr . trump’s favorite flying toy , he said in an interview on saturday . the jet , which once did duty with a commercial airline in mexico in the 1990s , has been famously renovated . it has a bedroom ; the fixtures are brushed with 24 - karat gold ; and the toilet seats were reupholstered with edelman leather , which also graces the eames chairs in ivanka trump’s den .
while the 757 might seem like an odd choice for a man who puts his net worth at $ 11 billion , and , records show , does not use the plane much to travel abroad , mr . trump has cited it and his other planes as proof of how he gets good value for his money . in the 1980s , for example , he paid $ 8 million to buy a 1968 boeing 727 from a financially troubled texas company , diamond shamrock , according to his book “the art of the deal . ” mr . trump said a smaller gulfstream jet would have cost more than twice as much .
“it was a little more plane than i needed , ” he wrote , “but i find it hard to resist a good deal when the opportunity presents itself . ”
in the interview on saturday , mr . trump said he did not own the five aircraft to burnish his brand , but agreed that the fleet had “promotional value . ” he added that he could get by without owning a boeing 757 but it was a “great luxury to have . ”
air travel is one of the largest expenses of mr . trump’s republican presidential campaign : a company he owns has charged the campaign approximately $ 3 . 7 million in travel costs since he announced his candidacy in june 2015 . using the 757 does not help keep costs down : it guzzles fuel and costs thousands of dollars an hour to fly , more than private planes being used to shuttle other presidential candidates . still , mr . trump has used it to crisscross the country , sometimes with just a small group of people aboard .

mr . trump said that he was aware of the boeing’s limitations and that he did not “use it that much . ” according to f . a . a . records , the boeing has flown about 333 hours between mr . trump’s announcement of his intention to run for president last june and march 16 , 2016 . during the same stretch , f . a . a . records show , the cessna has flown roughly 216 hours . a review by the times shows most of the hours logged were for campaign travel .
large jets are popular among professional sports teams and rock bands , which have to move large groups and equipment . still , some individuals and companies do own such aircraft . ronald w . burkle , a billionaire investor who owns stakes in a number of companies , including whole foods market , flies on a boeing 757 registered to his firm . las vegas sands , a casino operator run by the billionaire sheldon adelson , has several larger planes that are used to transport company executives and sands customers .
buying older planes has advantages : in addition to being less expensive , their depreciation costs are lower .
mr . trump said he liked older planes because they had been “tested” and had “been around . ”
as for mr . trump’s personal travel , he prefers to fly private . in 2009 , he decided to sell his boeing 727 , which was by then 41 years old . he replaced it with another used aircraft , the boeing 757 .
a company controlled by the billionaire paul allen , a founder of microsoft , had bought that plane in 1995 . mr . allen did a full renovation , transforming it into a luxurious private jet . he installed a master suite that included a bathroom and guest room . he put a conference table , overhead projector and bar in the center of the aircraft . this room had two couches and 11 single seats , according to f . a . a . records . elsewhere on the plane , mr . allen installed 12 sleeper seats , each with their own foldout monitors .
he agreed to sell it to mr . trump in 2010 , records show . the purchase price was not disclosed , though it was widely reported that mr . trump paid $ 100 million . the aircraft was insured at a value of $ 35 million in 2011 , records show , and aviation experts say it is currently worth about $ 18 million . boeing no longer makes 757s , but a 2015 boeing business jet would sell for approximately $ 80 million , and cost anywhere from $ 20 million to $ 40 million to outfit .
after mr . trump took possession of the 757 in 2011 he made a number of changes but did not fundamentally undo mr . allen’s initial renovation , records show . for instance , he kept the headboard in the master bedroom , as well as most of the chairs , couches and toilet seats mr . allen had left , choosing to reupholster them .
greg raiff , chief executive officer of private jet services , an aviation consulting firm and private - jet charter broker for corporations and individuals , said the boeing was an unusual aircraft for a man of mr . trump’s wealth . “buying a 25 - year - old 757 is like buying a bag of cheetos . it’s a lot of food for a low price , ” he said .
mr . trump’s three other aircraft are helicopters . two of those are 1989 sikorsky s - 76bs , one of which was used to give rides to children at the iowa state fair .
because of an editing error , an article last sunday about how donald j . trump’s brand has gotten a lift from his aging fleet of airplanes misstated part of the name of a television program that featured a segment on the renovation of one of his helicopters . it was cnbc’s “secret lives of the super rich , ” not “super lives of the super rich . ”
