Abstract: 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 ratio, while under the autoclave curing, the strength of glass powder composite mortar changes in a convex shape with the increasing of the replacement ratio. With the optimal content of 30%, its 60 day strength exceeds 17.6% of the reference cement mortar. It is suggested that the replacement ratio of glass powder is 30% to prepare glass powder composite mortar.
