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....
The work presented in this thesis was performed in order to generate knowledge of heat storage in building structures. The goal was to discover what material could most effectively reduce peak powers required by buildings by keeping buildings warm or cool without the necessity of using power....
The thermal and mechanical properties of concrete in which normal weight aggregate has been substituted with lightweight aggregates were investigated. The properties were found to be dependent on the volume fraction of the lightweight aggregate, as well as on the nature and quality of the aggregate. The addition of lightweight aggregates resulted in a decreased thermal conductivity, as well as a decreased thermal diffusivity in all samples. The compressive strength ...
A Portland cement-based composite was made using a copolymer as one of the ingredients, and the potential of the composite for the production of non-structural masonry systems was evaluated. It was found that the composite had a similar performance to that of commercial cellular concretes. The results also indicated that the incorporation of fly ash into mortars decreased the thermal conductivity of the composite....
