In order to alleviate the environmental problems of high energy consumption, high pollution and the like generated by the cement industry, the cement production process can be improved, but the adoption of auxiliary cementing materials to partially replace cement so as to reduce the consumption of the cement is the most effective mode. Glass materials are widely used in domestic and building materials because of their beautiful appearance and stable chemical properties, but waste glass is not biodegradable ifThe method adopts the modes of landfill or stacking and the like to treat, which causes serious land and environment pollution. The main component of the glass is amorphous SiO 2 The activity of the cement-based material can be stimulated by physical mechanical grinding or chemical methods, and the cement-based material can be used as a cementing material in cement-based materials.
At present, for the use technology of waste glass as an auxiliary cementing material, the patent application No. 201210251007.1 'a regenerated mineral admixture and the application thereof' is to grind waste glass powder to the specific surface area of 600m 2 More than kg, and is used as a mineral admixture for concrete.

In patent application No. 201710554048.0 composite gelled material using waste glass as raw material and its preparation modification method, cement and glass powder are ground to below 45 μm, but a nano modifier is used for modification. Patent application No. 202011337535.5 "a polymer for concrete using glass powder as raw material and its preparation method" uses different chemical agents, catalysts and initiators to adjust the molecular weight of glass material, and the improvement process is complicated. In the prior art, the activity of the glass powder is improved by reducing the fineness of the glass powder particles, but the economic cost is increased by excessively reducing the glass powder particles with higher energy consumption, and the possibility of unknown chemical reaction is increased by adding chemical reagents such as a modifying reagent, a water reducing agent and the like.
