Abstract

The invention discloses a high-temperature-resistant non-shrink early-strength grouting material and application thereof, and relates to the technical field of grouting materials. The high-temperature-resistant non-shrink early-strength grouting material comprises volcanic ash silicate cement 32.5R, perovskite flotation tailing, illite powder, shell powder, shale pottery sand, Swf-05 gelatin powder, water reducing agents, water repellents, expansive agents, rare-earth coupling agents and magnetized water. The high-temperature-resistant non-shrink early-strength grouting material and the application have the advantage that the high-temperature-resistant non-shrink early-strength grouting material is comprehensively obviously enhanced in the aspects of the physical properties, the frost resistance, the high-temperature resistance, the flowability, the mechanical strength and the like, is obviously progressed as compared with the prior art, and is good in applicability and long in servicelife.

Description

technical field [0001] The invention relates to the technical field of grouting materials, in particular to a high-temperature-resistant non-shrinkage early-strength 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 even...
