Abstract

The invention relates to a high-strength shrinkage-free grouting material. The high-strength shrinkage-free grouting material is prepared from the following ingredients in parts by weight: 33-38 parts of ordinary Portland cement, 7-9 parts of sulfo-aluminate cement, 9-11 parts of anorthite, 6-8 parts of silicon carbide, 6-8 parts of zinc hydrometallurgy waste slag, 3-4 parts of vermiculite powder, 3-4 parts of metakaolin, 1-2 parts of chopped carbon fibers, 1-1.5 parts of sodium borate, 1-1.5 parts of polyacrylamide, 1-1.5 parts of sodium myristoyl glutamate, 2-3 parts of sodium alginate and 1-2 parts of polycarboxylic acid high-performance water reducing agent. The high-strength shrinkage-free grouting material disclosed by the invention has excellent comprehensive performance, and the 28d compressive strength can reach 80MPa or more; and the high-strength shrinkage-free grouting material is good in fluidity, is free of shrinkage, is microswelling, has outstanding bondability to steel bars and is non-rusty to the steel bars, thereby being very applicable to beam-column-slab reinforcement, pavement rush-repair work and the like.

Description

technical field [0001] The invention belongs to the technical field of building materials, in particular to a high-strength non-shrinkage grouting material. Background technique [0002] High-strength non-shrinkage grout is a special mortar material with high fluidity, early strength, high strength and micro-expansion. It is composed of special cementitious materials, expansion materials, admixtures and high-strength aggregates. It is poured into In structural holes such as equipment anchor bolts and post-tensioned prestressed concrete structural channels, the slurry will flow by itself and fill the structural holes densely. At the same time, the volume of the slurry will shrink or expand slightly after hardening. Grouting materials can be divided into cement-based grouting materials, resin-based grouting materials and composite grouting materials according to different cementitious materials, among which cement-based grouting materials are the most widely used and mature. ...
