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