A large amount of natural stone waste in different grain sizes is exposed during operations such as extraction from quarries, cutting and polishing in processing plant. The amount of waste is reported to be around 20-30%. However, sometimes this rate can be up to 50-60% depending on cracks, discontinuities and sawability conditions of natural stone blocks. Andesite is one of the natural stones using in Turkey and world for a long time for production of building materials such as paving, curbs, stairs, windowsills in the construction industry. Due to andesite is a volcanic rock and high SiO2 content, its fine powder wastes exposed during stone processing have pozzolonic properties. As a result of this study, powder wastes of andesite extracted from Isparta-Direkli village have suitable properties in point of pozzolonic activity.
