Forsterite grouting material

Abstract

The invention provides a forsterite grouting material. The forsterite grouting material is prepared by mixing forsterite aggregate, forsterite powder, fly ash, a water reducing agent, a reinforcing agent, a micro expanding agent, an early strength agent, a flatting agent, a dispersing agent and cement, wherein the forsterite used is a green environmentally-friendly material which is internationally recognized; and the forsterite aggregate is stable in nature in a wider temperature range of between 50 DEG C below zero and 1,000 DEG C and is free from harmful gas or decomposition product generation. The grouting material prepared from the forsterite serving as the main material does not contain chloride ions, does not corrode any construction material and has obvious early strength effect, obvious reinforcing effect and high gravity flowing property; moreover, the grouting material also has the advantages of no weeping, no delamination, high bonding strength, no contraction, guaranteed tight bonding between existing concrete and fresh concrete, oil resistance, water soaking resistance and good durability.

Description

technical field [0001] The invention relates to a grouting material, in particular to a grouting material with forsterite as aggregate. Background technique [0002] As a material for construction and engineering construction, grouting material is widely used in the anchoring of anchor bolts, emergency repair of airstrips, fixing of nuclear power equipment, reinforcement of road and bridge engineering, machine bases, steel structures and foundation cups, and secondary repair of equipment foundations. Grouting, planting steel bars, concrete structure reinforcement and transformation, crack treatment of old concrete structures, installation of electromechanical equipment, installation of rails and steel structures, sealing of piles for static pressure pile engineering, thickening of wall structures and repair of water leakage, various Subsidence grouting of various foundation projects and various emergency repair projects, etc. [0003] The grouting material has the character...
