High-strength anti-freezing grouting material for building and preparation method thereof

Abstract

The invention discloses a high-strength anti-freezing grouting material for buildings, which comprises the following components in parts by weight: cement, quartz sand, carbide slag, waterborne epoxy resin, calcium nitrate, calcium lignosulphonate, a defoaming agent, an expanding agent, a retarder, steel fibers, a reactive diluent and water. The prepared grouting material has the characteristics of high strength, high corrosion resistance and high durability, the Portland cement and the sulfate cement are used as main components of the material, the carbide slag and the epoxy resin are crushed through a crushing process and added into the grouting material, the grouting material has the characteristic of high strength, and the toughness of the grouting material is enhanced by adding the steel fibers; according to the high-strength anti-freezing grouting material for the building, the breaking strength, the impact resistance and the anti-freezing effect of the grouting material are improved, the original high permeability of the grouting material is reserved due to the addition of the reactive diluent, and the high-strength anti-freezing grouting material for the building has high strength and high fluidity and can adapt to different grouting thicknesses by adjusting the proportion and the doping amount of the powder.

Description

technical field [0001] The invention belongs to the technical field of grouting materials, and in particular relates to a high-strength frost-resistant building grouting material. Background technique [0002] Grouting material is a kind of material that can exist in liquid form after being mixed with water, and is convenient to use hydraulic pressure, air pressure or electrochemical principles to inject into the inner space of cracks, cracks, pores and other internal spaces of the corresponding medium, and has the ability to cement and solidify, so that the leakage channel of the medium can be blocked. Materials with improved physical properties and mechanical properties. At present, cement-based grouting materials are a kind of grouting materials that are widely used and widely used. [0003] During the use of the grouting materials in the prior art, the flexural strength is low, the volume shrinkage is relatively large, and microcracks are prone to occur, resulting in the...

AI Technical Summary

Problems solved by technology

[0003] During the use of the grouting materials in the prior art, the flexural strength is low, the volume shrinkage is relatively large, and microcracks are prone to occur, resulting in the lack of close contact between the base masonry and the grouting material during use, and at the same time, it cannot be effective for a long time. Resisting the force of water will lead to leakage again in the later stage, and the anti-freezing effect is poor, thus affecting its use effect. Therefore, we propose a high-strength anti-freezing building grouting material and its preparation to solve the above problems
