Grouting material for road reinforcement and preparation method thereof

Abstract

The invention discloses a grouting material for road reinforcement. Key points of the technical scheme are as follows: the grouting material comprises the following components in parts by mass: 200-250 parts of broken stone, 150-200 parts of clay brick powder, 80-100 parts of cement, 80-100 parts of sand, 60-70 parts of waste concrete, 50-60 parts of fly ash, 20-40 parts of water glass, 20-30 parts of polypropylene fibers, 20-30 parts of methyl hydroxypropyl cellulose, 20-25 parts of admixture, 2-8 parts of water reducing agent, 2-8 parts of early strength agent, 2-4 parts of anti-freezing agent and 300-500 parts of water. According to the reinforcing grouting material, only a small amount of cement needs to be used, clay brick powder and waste concrete are used for replacing a large amount of cement, thus the cost of the grouting material is reduced, and the components are simple in composition and easy to prepare; by adding various waste materials and adaptive additives into the cement, the working degree of the grouting material can be improved, and the grouting material has high fluidity, high strength and good anti-cracking performance; the setting time of the grouting material can be prolonged, and the construction time is long; and the grouting material has the characteristics of high compressive strength.

Description

technical field [0001] The invention relates to the technical field of grouting material, more specifically, it relates to a grouting material for road reinforcement and a preparation method thereof. Background technique [0002] At present, most of the existing grouting materials in the field of building materials and civil engineering in my country are epoxy resin grouting materials and cement-based grouting materials. Epoxy resin grouting material has high production cost, complicated construction operation, poor bonding force with steel structure and concrete, and poor durability. The main cementitious material of commercially available and engineering cement-based grouting materials is pure sulphoaluminate cement or pure ordinary Portland cement. In recent years, the cement manufacturing industry needs to use a large amount of clay, destroying precious non-renewable cultivated land resources, releasing a large amount of carbon dioxide, and producing dust, mechanical vi...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned grouting material for road reinforcement only needs to use a small amount of cement, and a variety of waste materials are used to replace a large amount of cement, which reduces the cost of the grouting material, but there are still some disadvantages, such as steel slag and waste gypsum are required for production, Both of these two raw materials contain a lot of impurities. After production certification, the strength of the grout produced by them is not very high, and there is still room for improvement.
