EPS Blended Cementitious Plaster for Improved Thermal Comfort in Buildings
The use of green materials in building construction has become trendy to improve the thermal comfort within the buildings with minimized natural resources. This paper presents the development of a cementitious insulated plaster using Expanded Polystyrene (EPS) as partial replacement for fine aggregates. An experimental program was conducted by replacing the fine aggregates in the conventional plaster with EPS in the range of 0–200% by volume. A reduction up to 69% and 53% were noted in thermal conductivity and density, respectively due to the replacement of aggregates with EPS in the conventional mortar. From a trial and error process, the mix with 125% replacement by EPS was selected as the ideal mix for optimum thermo-mechanical performance. A numerical model was developed to examine the heat transfer behaviour through a wall/Plaster composite and the predicted results were in a satisfactory agreement with the experimental results. A reduction of 18% in the decrement factor and an increment of 20% in time lag were noted in the wall panels with the developed EPS-Cement plaster.
