Abstract: The study of the performance of raw clay bricks has made it possible to develop laterite in Eco village construction projects. Identification tests (particle size analysis, Atterberg limits, Proctor, shrinkage limit, and sand equivalent) made it possible to characterize the laterite, the sand, and the E1 mixture (70% laterite and 30% sand). By adding binders to E1, three other types of mixtures E2, E3, and E4 have been proposed. The improved E1... More

Abstract: Residents have chosen to be living in urban regions in recent years largely due to the accessibility of job opportunities and public services. These led to a fast increase in the amount of people live in urban regions and cities. As a result, a large amount of the property used for agricultural activities was transformed into factories, housing units, and highways. This also resulted in a decrease in food production, growth in food prices and... More

Abstract: “Push-and-pull” efficient structures have been inconceivable between XVIII centuries. It is because of the incapacity of obtain an efficient behaviour of tensioned material. Since XVIII centuries, architecture developed some structural knowledge generating novel structural forms in the architecture and engineering that were not known before. Tensegrities and tensioned structures were studied due to the knowledge of geometry and tension. Some... More

Abstract: Rice Husk Ash (RHA) has been found as a potential partial replacement for cement in concrete. This study attempts to make an evidence based evaluation of the sustainability and benefits of RHA utilisation as partial replacement of cement in road concrete works within Anambra State of Nigeria. The ashes of the rice husks collected from different locations were characterised. Direct interviews were conducted among the rice mill personnel and... More

Abstract: The construction method of continuous paving of the upper and lower base of the water stable macadam base can improve the construction efficiency, overcome the quality problems of the traditional layered paving of the upper and lower base, such as untimely curing, slow construction, poor interlayer bonding, contraction joint and interlayer, so as to ensure the construction quality of the water stable macadam. It is also the promotion and... More
