Published: May 2021

Abstract
This article aims to study the cooperative protection mechanism of the ecological environment. By using the method of literature analysis to understand the history and development of the ecological environment and collaborative protection. By making a comparison between domestic and abroad research environmental, we learn more protection methods. As the environment for human living, the ecological environment is affected by many factors such as population growth, economic growth and capital investment. Under the situation of social diversification, a collaborative protection mechanism mainly led by enterprises. The way of society and enterprises participate in it together has been proposed. In this regard, we believe that citizens should firmly establish the concept of collaborative governance. The government should integrate multiple forces to coordinate and co-administer the protection of the ecological environment. Departments at all levels should jointly improve the collaborative governance mechanism of the ecological environment. Relevant professional departments should improve the facilities for collaborative governance of the ecological environment level.

Authors: Pan Wei-Jun , Zhang Hengheng , Liu Tao , Wu Tianyi 
Published: May 2021

Abstract
Due to the various meteorological conditions encountered in the flight process, the uncertainty of FT will change. In order to obtain the FT error, the secondary surveillance radar and aviation weather forecast data are used for analysis. According to the propagation mechanism of uncertainty, an adaptive prediction model of FT uncertainty is established. The input parameters of the adaptive model include Mach number, flight distance, vector wind and temperature. Cluster analysis and linear regression analysis are used to analyze the accuracy of the model. Compared with the static time-of-flight prediction model, the dynamic time-of-flight prediction model can accurately predict the FT even if the weather conditions are very bad. The dynamic time-of-flight prediction model is applied to air traffic management to further test the accuracy of the model. The results show that the adaptive time-of-flight prediction model based on meteorological conditions can accurately predict the arrival time of a flight to a certain waypoint.

Authors: Wang Jing , Liu Yanling , Tang Dongqi 
Published: May 2021

AbstractSilty clay is the main structural stratum in Xuchang area. Based on the freeze-thaw cycle test, the influence of freeze-thaw on the water content and void ratio of silty clay is analyzed. The test results show that in the case of no recharge water source, the freeze-thaw cycle will cause water migration in the soil body, which will produce local high water content zone on the surface, and cause water loss and water content reduction, which is easy to cause soil loss Water shrinkage produces cracks. The results show that the higher the initial water content is, the faster the water content will be lost, and the different initial water content will tend to be the same when the freeze-thaw cycle reaches more than 15 times. With the increase of freeze-thaw times (5 times), the void ratio tends to be stable. The change of soil properties caused by water migration under freeze-thaw cycle plays an important role in soil stability control. The research results of this paper are helpful to carry out scientific and reasonable engineering prevention measures and provide basic data.

Published: May 2021

Abstract
An analysis was made on the routine data of meteorological stations, high-resolution satellite cloud images and the NCEP/NCA R 1°×1° reanalysis data during one instance of heavy snow precipitation that took place in northern Bazhou, Xinjiang on October 18, 2018, followed by a diagnostic analysis of physical quantities, including the large-scale circulation anomalies, upper and lower-level circulation conditions and water vapor transport. The following are the results: (1) the heavy snow precipitation process in northern Bazhou, Xinjiang is a heavy precipitation process largely caused by a convergence of severely cold air carried from Siberia by an upper vortex, and a strong, warm and humid air current from southwest China. During this weather process, the upper layer was dry and cold, while the lower layer was warm and humid; an obvious wind shear and convergence center appeared at 700hPa, 850hPa in the lower layer over northern Bazhou; the heavy precipitation area was located in the front of the trough bottom at 500hPa, on the left side of the lower-level shear line. 2) The secondary circulation formed on the right side of the upper-level jet stream entrance area at 200hpa and 300hpa enlarged the ascending motion of the heavy snowfall area, while the low-level easterly jet stream played a critical role in transporting and accumulating water vapor at 850hpa. 3) The variations of temperature at 850hpa and on the ground layer were of certain indicative significance to the forecast of the precipitation phase state, and the temperature field at 850hpa well-indicated the change from rain to snow. When the air temperature fell to 0.5°C or so, and the ground temperature fell below 0°C given T700hpa<-10°C and T850hpa<-2°C, it could be used as a criterion for the judgment of rain changing to snow. 4) The vapor condition, lifting force condition and unstable stratification condition in the numerically-forecasted physical quantity field, all had a good guiding effect on the heavy precipitation process that took place in the Yanqi Reclamation Area.

Published: May 2021

Abstract
Despite current global market conditions, a superior financial climate has lowered the demand for innovative low carbon building materials, with construction owners typically prioritizing project value, time, practicality, and aesthetics. This situation creates an obvious dilemma for practitioners and stakeholders, as carbon emission linked to the use of construction materials should decrease. This study presents the awareness among the construction professional in the northern states of Malaysia in relation to low carbon building materials (LCBM) via interviews and structured questionnaire surveys conducted with 93 companies of architects and civil and structural consultants. Of 76.9% valid responses, 44.6% to 51.4% claimed to be “Aware and have a good knowledge” about unfired earth bricks, prefabricated hollowcore floor system (PHFS), and prefabricated timber frame system; however, their usage remained low. PHFS provided satisfactory experiences to practitioners and ranked the highest (20.3%) in the recommendations for future projects. The sustainability and suitability of a particular LCBM is highly determined on-site, has project specific influences, and varies across structures types from project to project.
A review: Study on waste rubber as construction material

Published: May 2021

Abstract
Sustainable construction is highlighted in current development as the environmental issue is one of the major issues of global concern. This issue also relates to waste generated each year. The bulk of waste was estimated to increase, which can reduce space in the world and can cause pollution. Many researchers have come up with inventions and ideas to manage that situation. Some researchers use the waste rubber in a concrete mix as a partial coarse or fine aggregate replacement. The alternative in a concrete mix depends on the size of the rubber that is used and the appropriateness. In this paper, the critical perspective of waste rubbers discussed in detail. It is shown from the review that if compared with the existing one, there is some reduction in the workability and mechanical properties of concrete. Rubberised concrete, however, still has its superiority in terms of energy absorption. The use of pozzolanic material in the concrete mix, the application, the proportion of rubber and the choice of rubber types helps a lot to compensate for the weakness of rubberised concrete.
Recycled Glass Cullet as Fine Aggregate and Partial Cement Replacement in Concrete
Authors: Duraman S B , Li Q 
Published: May 2021

Abstract
Utilisation of recycled glass cullet in concrete has obvious benefits with respect to environmental conservation and sustainable development. The problems of rising landfills can be reduced. Reduction of primary aggregates for concrete where alternative materials would suffice can also be fulfilled. Glass also contains large amounts of silicon and calcium which means that in theory, is pozzolanic. However, the possibility of alkali-silica reaction (ASR) due to the presence of silica must also be addressed. Tests were performed to investigate the suitability of using cullet in concrete. A sieve analysis was performed to determine the size distribution of the cullet and provided basis to the range of samples that could be cast. Using cullet as partial replacement aggregate in concrete has resulted in minor increases in concrete consistence (workability) and minor reductions in compressive strength. When ground glass cullet (GGC) was used as 30% partial cement replacement, the consistence increased considerably, whilst the later age compressive strength was close or higher (depending on the mix proportions used) compared to the corresponding control mixes, which did not have GGC incorporation. The early age strength was lower and strength development was slower at early ages further suggesting likelihood of pozzolanic activity. Accelerated ASR tests have shown the occurrence of ASR in concrete mixes using cullet as replacement aggregate to be more than control mixes which used conventional aggregate. The magnitude of ASR was also found to be colour dependant-green coloured cullet resulted in less expansion than when using amber cullet. Qualitative microstructural analysis of specimen micrographs recorded in Secondary Electron Imaging (SEI) mode using a Scanning Electron Microscope (SEM) have shown that mortar specimens using cullet displayed more cracking at longer curing periods. Cracks propagated from, and surrounded the glass particles, further suggesting the occurrence of ASR activity. Depending on size classification used, glass cullet can therefore be recommended to be used as partial aggregate replacement and partial cement replacement in concrete. The possibility of durability attack due to ASR reaction must however be taken into consideration.

Authors: Mustapha Falmata Audu , Sulaiman Arizu , Mohamed Roslli Noor 
Published: May 2021

Abstract
Experimental research on the performance of fly ash and silica fume selfcompacting concrete filled steel tube (FSS CFST) stub columns under axial compression were conducted. The main parameters varied in the tests are steel tube’s diameter to thickness ratio, D/t (from 20 to 33), and yield strength (from 275.83 MPa to 350.51 MPa). The self-compacting concrete grade used as infill is M60 concrete with 50% and 10% addition of fly ash and silica fume, as partial replacement of Portland cement. The performance of FSS CFST stub columns is examined via the axial compression capacity, load-shortening response, and mode of failure of 12 specimens. The results indicate that the ultimate axial load capacity of the columns increases as the D/t ratio decreases. The FSS CFST columns have a maximum concrete contribution ratio of 3.72, a strength index greater than unity, and a ductility index of 2.431 and below. The predicted values obtained using Eurocode 4 closely estimate the test results with a mean of 0.927 and a standard deviation of 0.073. Conversely, the predicted values using ACI code are more conservative with a mean of 1.341 and a standard deviation of 0.089.

Published: May 2021

Abstract
Graded concrete is a material innovation in the field of civil engineering that aims to create environmentally friendly and economical construction materials. Previous research has shown that graded concrete increases material rigidity so that graded concrete can increase the level of serviceability of structures, indicated by the decreasing of deflection. Investigations on the performance of structures using graded concrete as building material need to be studied further with broader structural indicators. Further studies related to structural performance including base shear reactions, fundamental periods, storey stiffness, storey drift, and storey displacement, should also be discussed. In this study, a 3-storey residential building is modelled using ETABS in 3D approach. The effect of disparity in concrete strength on structural performance is examined. The buildings that employ graded concrete as a construction material can offer a better level of occupant comfort due to the lesser vibration period generated. The application of graded concrete in beam components can increase the value of the storey stiffness. It is because of the greater the modulus of elasticity, the greater the stiffness produced by the beam. It increases the confinement of the enclosed plate so that the stiffness of the building floor also increases. The use of high strength concrete in the beams will change the mode shape of the structure from flexure to shear type. In shear mode shape, the column will form a double curvature so that the mode shape of the structure tends to form a convex pattern. The benefit of the shear-type mode shape is the lesser value of storey displacement at the top level.

Published: May 2021

Abstract
Light weight foam concrete (LWFC) has a density between 400 kg/m3 to 1600 kg/m3 and has a minimum of 20% entrapped air in volume. The utilization of LWFC makes the building structure light and durable. Fibres can be used as reinforcement in LWFC to increase its structural behaviour in terms of strength and cracking pattern. This paper presents the potential review on the structural behaviour of LWFC consisting fibres. From literature reviews it can be seen that great number of researches used the fibres such as coir, Polyethylene terephthalate (PET), polypropylene (PP), steel, and glass fibres in LWFC. The mechanical and structural properties of LWFC slab were reviewed. From the previous studies it was concluded that LWFC 0.6 % glass fibre, 0.4 % hybrid steel fibre and 0.3 % of coir fibre were optimum where LWFC had high mechanical and structural behaviour of LWFC slab compare to control sample.

Abstract
Concrete is widely used in the engineering field, particularly in construction. Despite its widespread use in the construction industry, concrete is brittle and has a number of drawbacks, including low tension and crack resistance. As a result, many researchers discovered a way to enhance concrete ductility through adding micro steel fibers (MSF) as a reinforcement. This study explores the impact of MSF on slump height, and the toughness of various concrete. To obtain relevant paper for this research, a systematic literature review was used. When 0.5% to 2% MSF were present in the concrete composite, the result shows a positive increment on its strengths. Meanwhile, the toughness impact of self-compacting concrete (SCC) is reduced depending on what type of water used during the mixing process. Aside from that, adding 0.5% to 2% MSF increases the tensile strength of SCC and ultra-high performance concrete (UHPC). Ultimately, incorporating MSF with concrete to increase the durability is a great idea.
