Abstract
The effect of carbon dioxide sequestration by Sandcrete structures was investigated as a means of reducing CO2 emissions. Experiments were conducted to determine the concentration of trioxocarbonate IV (CO3
2-) in sandcrete samples as well as its effect on soil pH. The results showed that the presence of CO3
2 - in sandcrete samples evidenced the process of carbonation in sandcrete structures and other cement-based material which provides an alternative means of CO2 Sequestration. Also, the concentration of CO3
2 - varied along heights and horizontal distance within sections of the sandcrete structure. The acidic nature of the soil close to some sections of the sandcrete structure experienced varying pHs of 6.14 - 6.35 which gave room for enhanced leaching which seriously undermines the strength of the sandcrete structure. The percentage concentration differential in the horizontal and vertical directions, were found to vary widely from 5-46%. This constitutes a potential danger i.e. cracking and possible collapse of the structure. The results of calculated diffusivity values and concentration gradients of the carbonate ion conformed with results obtained using a predictive model which helped in monitoring the migration patterns of CO3
2 - in the sandcrete structure.

Abstract
The durability and stability of masonry structures throughout usage can be affected by producing process, material properties and environmental conditions such as moisture hence finding out the factors affecting durability of clay bricks is vital so as to produce bricks of high strength which will absorb less water. The effect of stabilizing clay for the production of interlock bricks using lime at various percentages was investigated. Soil type used in the production of interlocking bricks was A-6 soil using the AASHTO system of soil classification. Maximum reduction in Liquid Limit and Plastic Limit of the clay material was observed at 8% addition of lime. The Specific Gravity rose from initial of 2.71 at 0% to 2.85 at 10% addition of lime. The maximum reduction of Average Water Absorption (AWA) of clay modified with lime was observed at 8% and the value of AWA recorded was 13.3%, which brought the clay brick to the first class designation from the second class designation of 0% of lime addition. The compressive strength reduced at 8% for all the sampling period of 28 days, the compressive strength test is lower than specification as such the bricks can be used in non-structural member in construction.

Abstract
Aluminum dross waste creates environmental burden for manufacturers and hence the need for its re-use. This experimental research assessed the engineering properties of modified asphalt using aluminium dross as a filer material. The aluminium dross used was obtained from a steel manufacturing industry. Elemental composition of the oxides was done using XRF equipment. Sieve analysis of the aluminium dross and the coarse aggregate was also assessed. Additionally, ductility, penetration, ball and ring and Marshall stability test were used in achieving the aim of this research. The outcome of the research revealed that 10-20% addition of the aluminium dross improved the stability of the modified asphalt. Physical observation revealed that the utilization of the waste stiffened the modified asphalt. The result showed that the addition of aluminium dross reduced the VMA. This will also increase the asphalt mix flushing. Additionally, at higher percentage addition of the waste the stiffness of the asphalt mix increases especially at a higher temperature. The use of this material will help in the reduction of solid waste and reduce the cost of management while reducing the cost of pavement construction in track with the trash to treasure drive.

Abstract
Heat transfer is of immense importance in many engineering studies. Monte Carlo technique are broadly utilized in the operation research fields and atomic physics in which difficult problems above the existing tools of theoretical mathematics were resolved. The target of this study is to confirm the short duration in which heat transfer occurs in a quadrilateral slab where the temperature is provided throughout the borderline. An effort was made towards providing appropriate condition for the explanation of the heat transfer in a substance. The Shrinking Periphery Monte Carlo technique was utilized to obtain heat transfer in a helical pattern, upward and downward movement, which was compared with the standard Monte Carlo technique. The result of the study showed that the dimension of the quadrilateral slab determines the duration to calculate temperature dissemination in the system. The study revealed that the helical pattern is the shortest route in computing run time for temperature dispersal in a slab. The helical pattern is paramount in determining temperature distribution in a quadrilateral slab of stable state. The application of this technique to examine the conduction of heat in quadrilateral slabs produced good outcomes.

Abstract
This research compares the Reliability-Based Design (RBD) method with the Eurocode 2 (EC2) for a singly reinforced concrete beam. Advanced First Order Second Moment (AFOSM) was used and the equation for the ultimate limit state design consideration for Moment of resistance and Applied moment was applied. The parameters which were all functions of the Ultimate load, G were replaced respectively with variables and their derivatives G(x) obtained with being the characteristic strengths of concrete and the yield stress of steel respectively. Given the original vector space and the transformed reduced vector space, the Taylor series was used to expand the reduced vector space and thus reliability index ßx expressed. The procedure was then coded using JAVA to produce the Reliability Index and Probability of failure for respective steel ratio. The required probability index of 3.9 corresponds to 0.048% of the steel ratio. Typical analysis of a singly reinforced beam according to EC2 for b=300mm, h=500mm, d=447mm, cover of 40 mm, gave a steel ratio of 1.31 %. Comparing this to the reliability-based design of 0.048%, the code provision exceeded the RBD output by 2000 times and 63 times the minimum reinforcement requirement by the code.

Published: March 2021

Abstract
The growing problem of containing wastes in developing countries has led to endless research on the chances of converting these wastes to materials for sustainable engineering construction. This study through experimental assessment explores the potentials of cement kiln dust (CKD) and rice husk ash (RHA), in circumventing the inadequacies often encountered in deficient tropical soil thereby ensuring profitable engineering construction. Specimens were prepared by blending dosages of 0, 2, 4, 6 and 8 % CKD as well as 0, 3, 6, 9, 12 and 15 % RHA by requisite weight of soil. The investigated outcomes revealed increasing cation exchange capacity (CEC) with corresponding increase in pH for the various increased CKD-RHA composition. The Atterberg limits indicated a reduction trend with increasing CKD-RHA blend, signifying a drastic improvement in the plasticity tendency of the soil. While the maximum dry density (MDD) decreased with up shoot in optimum moisture content (OMC) at varying combined dosages of CKD and RHA, the CBR (soaked condition) increased steadily from 5 % (natural) to peak of 35 % at 8 % CKD / 15 % RHA blend. The highest CBR value in this study was not below the criterion of 20 – 30 % for sub-base as well as 10 – 15 % for subgrade road material. The regression analysis and analysis of variance from laboratory results validated the experimental outcome of using CKD-RHA blend to expressively enhance deficient lateritic soil. The outcome of this study has shown that CKD-RHA is recommended in improvement of strength of weak soil for either sub-base or more fittingly, subgrade of flexible pavement. Hence, using these waste materials will solve the twofold objective of proper waste management and good engineering materials for sustainability in construction of subgrade of flexible pavement.

Abstract
The continuous rise of world population is putting much pressure on the housing and infrastructure stocks available to the society, thereby accentuating the need for more constructions and of course, more pressing demands on the depreciating natural resources. Today, the most used construction materials are concrete and steel, but the amount of pollutants deriving from their production has remained a source of great concern to the world. Finding solution to this environmental challenge has given rise to Sustainability Development Goals (SDGs), aimed at making the planet earth more conducive to living organisms. One of the viable approaches to reduce the high demand of construction industry on depreciating natural resources is the recourse to using more of renewable materials like timber. Timber is one of the few construction materials that have served all the ages of human lives in providing shelter. In this moment of pressing needs for more shelter and infrastructure, needed to make life more comfortable for man, the use of this renewable material must be sustained, but the strength characteristics must be known for more efficient and safe use. This research reviews recent characterization of some Nigerian timber species. This research emphasizes some good strength properties of recently reviewed Nigeria timber species, which will build the confidence of designers on safe judgment and choice of structural timber, help to reduce the cost of construction, thereby making residential houses more affordable to the lower class of the society. This will help to build a sustainable eco system for all.

Abstract
The impact of fire on concrete buildings has been found to tend towards strength reduction of the concrete building. Fire-retardant paints help to reduce the impact of fire on buildings and many researches are on to improve on fire-retardant paints. To this end, this paper investigated the fire-retardant properties of the bio-based extract of Acalypha wilkesiana in emulsion, text-coat and gloss paints. Acalypha leaves were subject to extraction in water and kerosene for three days. Emulsion, text-coat and gloss paints were produced. The fire point of the paint samples with a varying mass of extract was obtained to compare the flammability and obtain the optimum mass of extract needed for the best performance. The cube coated with 2 layers of text-coat paint of 0.45 g yielded the highest compressive strength. The best performing type of paint was text-coat paint. The coarse sand added during the production of text-coat paint assists in protecting the substrate material. Emulsion paint was the next best performing paint type while gloss paint was not advisable to be used for this purpose. The introduction of Acalypha wilkesiana as an additive had the fire point of the sample increased alongside the ignition time and the optimum mass of Acalypha wilkesiana extract that yielded the best fire-retardation of the paint was found to be 0.45g.

Published: March 2021

Abstract
Inefficient material utilization results in extra pressure on the environment for the extraction of more material to meet production demand and therefore makes the environment unsustainable. The survival of the manufacturing industry depends on its ability to balance several requirements to meet up with dynamic market demand particularly materials for production ranging from raw materials, intermediate materials to spare components for maintenance. In the past, sustainability and efficiency were no challenges to the manufacturers and material extraction from the environment was always below replenishment. Presently, the reverse is the case where the demand for production material has become incessant and surpasses supply on account of increasing population and modern manufacturing practices thereby resulting in irresponsible exploitation of raw material. This paper aims to evaluate the current efforts in the topic area to gain insight into the impact of material efficiency on the manufacturing performance concerning other manufacturing strategies alongside the environment. It appears from the review that the balance between manufacturing material extraction from the environment and the replenishment rate determines the sustainability of both the manufacturing system and the environment. Hence material efficiency is an index for sustainable manufacturing strategy. We recommend the future research direction to looks into the development and determination of balance between manufacturing material extraction from the environment and the replenishment rate for a sustainable future manufacturing.

Published: March 2021

Abstract
The main compartment that determines the functionality of the adsorption refrigerator is the adsorption refrigerator tube (ART). Many scientists have suggested certain ART configuration that would help improve its adsorption performance. The focus of the research is to determine causes of the ART malfunction via material failure. The linear driving force (LDF)-based models and the chemical kinetic reaction were taken into account to determine the chemical equilibrium of the material. It was observed that the successes of the adsorption refrigerator depend on the source material of the activated carbon and the level of impurity in the activated carbon.

Published: March 2021

Abstract
A ns Nd:YAG pulsed laser has been employed to produce plasma from the interaction with a dense target, generating continuum and UV and soft x-ray emission depending on the laser parameters and target properties. The laser hits solid and gaseous targets producing plasma in high vacuum, which was investigated by employing a silicon carbide detector. The two different interaction mechanisms were studied, as well as their dependence on the atomic number. The photon emission from laser-generated plasma produced by solid targets, such as boron nitride (BN) and other elements (Al, Cu, Sn and Ta) and compounds such as polyethylene, has been compared with that coming from plasma produced by irradiating different gas-puff targets based on N2 and other gases (Ar, Xe, Kr, SF6). The experimental results demonstrated that the yields are comparable and, in both cases, increase proportionally to the target atomic number. The obtained results, focusing the attention on the advantages and drawbacks of the employed targets, are presented and discussed.
