large amount of granite powders wastages were produced during the process stone processing, therefore research on recycling and utilizing was carried out. Based size distribution specified by laser particle analyzer, influence powder mechanical properties cement mortar out through grinding test scanning electron microscopy (SEM). The result shows as follows. flexural compressive strength with replacement rate 20% is highest when same incorporated. When same, smaller is, higher is. 20%, ranging from 0μm to 45μm, filling effect can be fully utilized best.
