Abstract

The invention relates to a cement hardening agent and a preparing method thereof. The hardening agent is prepared from 1-90% of silica sol, 1-90% of alumina sol, 1-20% of water, 1-10% of a stabilizing agent and 0.01-5% of a wetting agent, wherein the mass of the hardening agent is considered as 100%. Silica sol and alumina sol are adopted as main components, and hardness and abrasion resistance of cement can be improved substantially. Meanwhile, the preparing method is simple and convenient, which is beneficial for reducing industrial production cost. Paint can be prepared by stirring and dispersing the raw materials through the preparing method, the preparing technology is simple, easy to implement, convenient to operate and beneficial for large-scale industrial production and reduces industrial production cost, and the cement hardening agent is particularly suitable for heavy load bearing cement-based terraces of an industrial factory building, a parking lot and the like and has broad application prospects.

Description

technical field [0001] The invention belongs to the technical field of cement infrastructure materials, in particular to a cement hardener and a preparation method thereof. Background technique [0002] As the most important modern building material, cement-based building materials have the characteristics of high strength, low cost, and various types. However, cement-based building materials often have interconnected capillary pores in the material due to insufficient batch stability, inadequate construction and maintenance, and even disadvantages such as sanding and cracking, resulting in reduced performance of the material or loss of certain properties. Function. Through post-improvement of cement-based materials, the performance of cement-based materials can be improved, which has significant environmental and economic benefits. The Chinese invention patent application with publication number CN201110354668.2 discloses a lithium-based concrete sealing and curing agent,...
