In order to improve the mechanical properties of glass powder composite mortar,the preparation method of autoclaved aerated brick was referred.The glass powder composite cement mortar was prepared by autoclaved curing with different proportion of waste glass powder instead of cement.The mechanical property changes of waste glass powder composite mortar were studied by diffraction of X-ray,scanning electron microscope and other experimental methods.The results show that under the standard curing,the strength of waste glass powder composite mortar decreases with the increasing of the replacement...
