- Description
- In this study, a structural lightweight concrete with function of indoor temperature control was developed by using thermal energy storage aggregates (TESA). TESA was made of porous structural lightweight aggregate (scoria) impregnated with liquid phase change material (PCM) and was coated with epoxy resins and mineral admixtures. TESA concrete mixes were prepared by substituting coarse aggregates with varying amounts of TESA. The properties of TESA concrete were investigated through thermal performance and water absorption analyses. The results concluded that the concrete with macro-encapsulated PCM can be used to improve the thermal performance of building, particularly during the summer the energy consumption for cooling can be significantly reduced. It was found that PCM in LWA was appropriately encapsulated and did not have negative impact on the properties. The coating materials covered the surface of porous aggregates significantly resulted in the reduction of permeability.
