Abstract

The purpose of this study is to investigate the use of Izmir (Menderes-Cumaovasi) expanded perlite as a construction raw material by determining its characteristic properties, as well as its physical properties at different temperatures (up to 600 degrees C). The perlites, having glassy, porous structure, were found to contain 70.68% SiO2 and 13.04% Al2O3. The physical properties of the perlites changed with temperature. The highest surface area, 524 m(2)/g, was obtained at 400 degrees C. The physical properties were found to have high statistical relation. It was concluded that expanded perlite aggregates could be used as a construction raw material.
