Preparation method of waste glass mortar and waste glass mortar

The invention provides a preparation method of waste glass mortar and the waste glass mortar, and the method comprises the following steps: (1) uniformly mixing mixed alkali with Na2SO4, then uniformly mixing with waste glass powder, and putting the mixture into a high-pressure kettle for hydrothermal treatment; drying the activated glass powder in a constant temperature box, and grinding the dried glass powder into micro powder of 75-300 microns; (2) pouring the activated and ground glass powder, ordinary Portland cement and standard sand into a stirrer for mixing and stirring, then adding water, and continuously stirring to obtain waste glass mortar subjected to physical-chemical-hydrothermal combined activation; the mass ratio of the ordinary Portland cement to the standard sand to the glass powder to the Na2SO4 to the mixed alkali to the water is 1 : (1.575-2.025) : (0.225-0.675) : (0-0.06) : (0-0.06) : 0.47. The waste glass mortar prepared through the scheme is good in compression resistance and breaking
