Abstract

The invention discloses a quick-hardening rustless cement based grouting material, and belongs to the technical field of grouting material. The quick-hardening rustless cement based grouting materialcomprises following raw materials: portland-pozzolana cement 32.5R, perovskite floatation tailing, illite powder, shell powder, shale pottery, Swf-05 rubber powder, a water reducer, a water repellent,an expanding agent, a rare earth coupling agent, and magnetic water. The physical properties, the anti-freezing performance, the high temperature resistance, the fluidity, and the mechanical strengthof the quick-hardening rustless cement based grouting material are improved obviously. Compared with the prior art, the advantages are that: the applicability is high, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of grouting materials, in particular to a fast-hardening and non-rusting cement-based grouting material. Background technique [0002] The grouting material is made of high-strength materials as aggregate, cement as binder, supplemented by high fluidity, micro-expansion, anti-segregation and other substances. It adds a certain amount of water at the construction site, and it can be used after stirring evenly. The grouting material has the characteristics of good self-flowing property, rapid hardening, early strength, high strength, no shrinkage, and slight expansion; non-toxic, harmless, non-aging, no pollution to water quality and surrounding environment, good self-tightness, and anti-rust. In terms of construction, it has the advantages of reliable quality, reduced cost, shortened construction period and convenient use. Fundamentally change the force of the equipment base, so that it can evenly bear all ...
