An inorganic grouting material capable of stopping water and reinforcing structures, its preparation method and application

Abstract

The invention discloses an inorganic grouting material capable of stopping clear water and reinforcing the structure and its preparation method and application. The inorganic grouting material comprises component A: 3-4 parts of potassium silicate solution, sodium silicate solution 2 to 3 parts, 1 to 1.5 parts of dispersant, 0.1 to 0.2 parts of defoamer, 10 to 13 parts of water; component B: 0.1 to 0.2 parts of water reducing agent, 20 to 25 parts of superfine cement, 8 to 2 parts of mineral powder 9 parts, silica fume 0.5-0.7 parts, fly ash 2-3 parts, flocculant 0.5-0.6 parts, expansion agent 0.5-0.6 parts, retarder 0-1 part, water 10-13 parts. The invention is an inorganic grouting material based on cement-based materials, which can achieve the effect of solidification in a very short time, can adjust the curing time, solidify and stop water in a short period of time, will not be washed away by water flow, and can be cured after hardening. It plays the role of strengthening the structure, and the hardened body does not shrink, and has the same life as the concrete structure, which can effectively promote the development of the industry of building grouting, waterproof and plugging.

Description

Technical field [0001] The invention belongs to the construction of a building, and more particularly to an inorganic grouting material which can only reflect the water and reinforcement structure and the preparation method thereof. Background technique [0002] The crack of concrete is inevitable. Once the crack is in a through shape, the water will leak from the crack, so the cracks must be grown in the form of aqueous water. Commonly used grouting materials include inorganic grouting, such as ultra-fine cement or conventional cement water glass, organic grout, such as foamed polyurethane (aqueous polyurethane or oily polyurethane) or epoxy resin. The advantage of ultra-fine cement injections is that the hardening strength is high, and the adhesive strength of the peripheral concrete is good, and the surrounding concrete structure is in the same material, the life is long, but it is easy to contract after hardening, and the coagulation time is uncontrollable, and the water pres...

AI Technical Summary

Problems solved by technology

The advantage of ultra-fine cement grout is that the hardened body has high strength, good bonding strength with the surrounding concrete, and the same material as the surrounding concrete structure, and has a long life, but it is easy to shrink after hardening, and the setting time is uncontrollable. Larger open water is easily washed away

Although conventional cement plus water glass can adjust the hardening time, it can achieve the effect of quick setting in a short time, but the hardened body is easy to shrink, and its compactness will also be affected

The advantage of foamed polyurethane is that it foams when it encounters water, and it can stop water quickly, and the effect is obvious. However, the foam has no strength and cannot reinforce the structure. will shrink

The advantage of epoxy resin is that the hardened body has high strength and can strengthen the structure, but it is difficult to cure in open water environment. Even if it is cured, the bonding strength with the surrounding concrete will be weak, and the polymer material is not UV resistance, easy to aging failure
