Abstract
In this study, thermal and mechanical properties of lightweight concretes obtained by using volcanic slag as aggregate are analyzed. Volcanic slag is a natural material that is light and low in thermal conductivity. Such slags have large reserves in many parts of the Eastern Anatolia Region. Volcanic slag obtained from the quarries in Yeniköy district of Elazig province was used in the production of concrete as aggregate for the study. Samples were subjected to thermal conductivity, water absorption and drying, compressive and tensile strength and abrasion tests. The following results were obtained from this study: i) Volcanic slag is lighter than sand in terms of aggregate, ii) When examined in terms of strength, it can provide BS14 concrete class required by standards. iii) It is a good building material due to its thermal and sound insulation properties.
