Abstract: The twenty-first century is one of the most complex in the history of humanity, mainly due to the ecological crisis it is going through. The construction sector generates about 40% of CO2 emissions into the environment; the foregoing should motivate this sector to seek new alternatives to develop new building practices. Taking these current needs into account, this document classifies and presents a multidisciplinary solution that integrates... More

Abstract: The design of columns relies heavily on the basis of Leonhard Euler's Theory of Elastic Buckling. However, to increase the accuracy in determining the maximum critical load a column can withstand before buckling, a constant was introduced. This dimensionless coefficient is K, also known as the effective-length factor. This constant is often found in building design codes and varies in value depending on the type of column support that is... More

Abstract: Curing methods are one of the most important factors in determining the quality and compactness of cover concrete. The effect of curing methods on the water absorption and sorptivity coefficient of cover concrete with the substitution ratio of fly ash (FA) and ground granulated blast slag (GGBS) for cement between 30 wt% and 40 wt% was studied by capillary water absorption test. The vacuum saturation test and mercury intrusion test were employed... More

Abstract: Formwork is the temporary mould in the construction that is fabricated based on the drawing and design of the structure and into which the concrete is poured to form the required structure. Formwork is an essential part of the construction as it has been used by the Romans. The formworks must be strong enough to withstand all types of loads. The joint must be in proper condition to avoid any kind of leakages. The materials used for the formworks... More

Abstract: This research was carried out to evaluate the relationship between the incorporation of calcite precipitation bacteria, sporosarcina pasteurii using calcium lactate as nutrient source and the properties of calcined clay and limestone powder blended self-compacting concrete. Ten mixes were designed and designated S0 to S9 with S0 the control (without bacteria and nutrient) and S1 to S9 at varying bacteria and calcium lactate concentrations and... More

Abstract: The target of traditional thermal conductivity of wall research is the spatial distribution form. In these studies, the change of thermal conductivity with temperature is neglected. Meanwhile, case studies are always used. This method needs large computation and it is hard to obtain the optimal result. In order to overcome the problems, a new approach has been put forward in this paper. Different from the traditional approach, the new approach... More
