AI Technical Summary

Problems solved by technology

However, the cement slurry has a long setting time, and it is easy to lose and be washed away by water under dynamic water conditions; the strength development is slow, and it cannot meet certain special requirements; the condensation is greatly affected by temperature, and construction is difficult in low temperature environments. Cement slurry is easily washed away under water, and at the same time, due to the long initial setting period, a large amount of materials are wasted after being washed away

Description

technical field [0001] The invention relates to the field of composite grouting materials, in particular to a composite grouting material and a preparation method thereof. Background technique [0002] Grouting material refers to pouring into the cracks and holes in the bottom layer, rock or structure under a certain pressure to reduce extrusion leakage, improve the physical and mechanical properties of the cracked rock mass, and increase the overall stability of the foundation of buildings and structures. A fluid material that improves its impermeability, strength, and durability. There are many kinds of grouting materials, generally divided into inorganic grouting materials and organic grouting materials. [0003] Inorganic grouting materials are mainly cement slurry, cement mortar, ultra-fine cement slurry, clay slurry, cement clay slurry, cement lime slurry, etc. Among them, cement slurry is currently the most widely used inorganic grouting material with the largest de...
