Abstract

The invention discloses a solid grouting material and a preparing method thereof.The solid grouting material is prepared from, by weight, 30-40 parts of casting dust, 30-40 parts of slag, 30-40 parts of coal ash and 40-42 parts of water glass.Casting dust comprises one or two of sand conditioning dust and hot method reclamation dust.The preparing method comprises the steps of weighing the components by weight, conducing uniform dry-blending on the components except water glass, and then adding water glass for uniform stirring, so that the solid grouting material is obtained.Waste resources are fully utilized, production energy consumption is reduced, environment damage and pollution are reduced, and environment friendliness is higher.High compressive strength and tensile strength can be obtained simply through ordinary curing, and the material also has the advantages of being adjustable in condensation speed, high in early strength, high in durability, low in permeability, high in nuclear radiation resistance and resistant to high temperature and corrosion.

Description

technical field [0001] The invention belongs to the technical field of new reinforcement materials for civil engineering, and in particular relates to a solid grouting material and a preparation method thereof. Background technique [0002] Grouting is to make grout from materials with filling and bonding properties, and inject it into the cracks or holes in the formation with grouting equipment. After the grout is condensed and hardened, it will form a "slurry" with high strength, strong waterproof and anti-seepage performance and good chemical stability. stone body" to achieve the purpose of filling, reinforcement, anti-seepage and plugging. With the large-scale construction of houses, bridges, highways, tunnels, mines, dams and other projects in our country, grouting materials have been widely used and developed due to their strong practicability and convenient construction. Grouting materials are generally divided into two categories: solid grouting materials and chemic...
