A technical evaluation on the determination of thermal comfort parametric properties of different originated expanded and exfoliated aggregates

Abstract

Nowadays, with increasing global warming, there are increasing concerns about energy saving in many branches in the world. One of these branches is the construction sector. In the construction sector, various building materials are produced to minimize energy losses from buildings. Among these construction materials, cement mortars are widely used. Cement mortars are produced from various raw materials and aggregates. The aggregates, which have expansion properties between these aggregates, have high insulating properties due to their porous structures. In this study, four different expanded/exfoliated aggregates, which are expanded perlite (EP), expanded clay (EC), expanded glass (EG), and exfoliated vermiculite (EV), with suitable unit weight and pore structure for thermal insulation were used in cement mortar. At the end of the experimental study, the thermal behavior of the cement mortars produced was investigated. According to the results of the research, it was determined that the cement mortar produced with expanded perlite was the most suitable for the heat insulation between the tested aggregates.
