Abstract

The invention discloses a high-performance grouting material, which is prepared from the following raw materials in parts by weight: 44 to 48 parts of Portland cement, 24 to 30 parts of quartz sand, 28 to 32 parts of mineral waste residue, 26 to 28 parts of bentonite, 24 to 25 parts of carbide slag, 20 to 24 parts of nano-silica sol, 16 to 18 parts of inorganic mineral fiber, 4 to 6 parts of waterreducing agents, 1 to 3 parts of anti-foaming agents and 1 to 2 parts of anti-foaming agents, wherein the substance mass ratio of the mineral waste residue to the bentonite to the carbide slag to thenano-silica sol to the inorganic mineral fiber is (9 to 13) to (6 to 10) to (5 to 7) to (2 to 4) to 1. The high-performance grouting material has the advantages that the strength of the grouting material is high; cracks cannot easily occur after construction; high practical value and good application prospects are realized.

Description

technical field [0001] The invention relates to the technical field of grouting material, in particular to a high-performance grouting material and a preparation method thereof. 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 stress on the base of the equipment, so that it can eve...
