Abstract

The invention provides a two-dimensional reinforced hydraulic cementing material based on granite stone powder, which is prepared by weighing the following raw materials, by mass: 45-60 parts of granite stone powder, 25-35 parts of furnace bottom slag, 7-12 parts of cement clinker, 2-3 parts of desulfurized gypsum, 1-3 parts of calcium hydroxide, 1-3 parts of water glass, 1-3 parts of sodium hydroxide and 0.03-0.04 part of few-layer graphene. The hydraulic cementing material is prepared by mixing the raw materials, so that the deep processing technology of the granite stone powder is expanded, the granite stone powder is fully utilized, the problem of waste of land resources and mineral resources caused by stacking of the granite stone powder is solved, and the hydraulic cementing material can replace cement, mineral powder and fly ash to be used in concrete preparation; the problem of shortage of cement, mineral powder and fly ash resources is solved, and the preparation method has the advantages of being easy to operate, safe, reliable and low in cost.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to a two-dimensional reinforced hydraulic gelling material based on granite stone powder. Background technique [0002] With the rapid development of my country's stone industry, the generation of stone powder is also increasing, but the comprehensive utilization rate of stone powder, especially the utilization rate of granite stone powder is very low. As a natural mineral resource, the main disposal method of granite stone powder is still passive stacking, which not only seriously wastes land resources and mineral resources, but also causes a certain degree of damage to the ecological environment. At present, the application of granite stone powder in concrete mainly includes two ways of using granite stone powder as mineral admixture and fine aggregate. within a small dosage range. Therefore, how to improve the utilization rate of granite stone powder is a more urgent problem. ...
