Lightweight dry mix shotcrete was mixed with an expanded perlite aggregate (EPA) and the thermal and mechanical properties of the resulting samples were tested. A number of EPA/sand ratios were used to produce the samples. The TPS instrument was used to measure the thermal conductivity of the samples after 28 days, and values revealed that the thermal conductivity of the samples decreased with the amount of EPA added. The splitting ...
This article studied the thermal conductivity of samples of autoclaved aerated concrete with various densities at high temperatures in order to produce data that could be used to assess and predict the performance of buildings during a fire. The mica sensor was employed for high temperature measurements. The values obtained by the authors experimentally were then compared against the reference values provided by national and international standards for high temperature ...
This study investigated the use of oil palm shell as an additive for use in concrete. As the construction industry searches for methods to increase sustainability, using by-products produced by other industries to reduce the amount of cement required to produce concrete has become more popular, Oil palm shell is available in large quantities as an industrial waste product, is lightweight, and has the potential to help with thermal insulation. ...
The purpose of this article was to investigate the thermal performance of light steel structures. Responsible and sustainable building practices are becoming the norm, and light steel can provide a good alternative to other construction materials. However, it is important that the finished building has good thermal management characteristics to reduce energy consumption. The authors of this study looked at the thermal characteristics of buildings fabricated from a combination of ...
A numerical model is developed to describe the thermal conductivity, hydration, and moisture content of Portland cement mortar specimens. In order to develop the model, the thermal conductivity and specific heat of the mortar specimens were measured using the transient plane source method. The model was able to correctly describe the evolution of heat and the degree of hydration in both semi-adiabatic and steam curing conditions....
