Perlite is a natural building materials contribute to global warming positive thanks to its isolation and lightness characteristics as concrete aggregate with usage of in construction sector. In research results, about %74 of world perlite reserves was determined to be in Turkey. It is thought that energy of fairly hard obtained will provide more efficient usage thanks to efficient usage of the natural reserves. Such approaches will provide to reduce of environment pollution in the usage of energy. In this study, with different characteristic usability of expanded perlite aggregate was researched in raw perlite aggregated light weight concrete. 7 different mixtures were prepared in volume at 10% ratio by using 3 different expanded perlite aggregate instead of raw perlite aggregate. With prepared light weight concrete mixtures 100x100x100 mm sized cube samples were produced. 28 days compressive strength, unit volume weight and water absorption ratio of these sample were researched. As a result, with suitable characteristic usage of expanded perlite aggregate was understood to be effective on the mechanical and physical properties of perlite aggregated light weight concrete.
