Grouting material for connecting prefabricated assembled concrete component sleeve
The invention discloses a grouting material for connecting a prefabricated assembled concrete component sleeve. The grouting material is prepared from the following raw materials: sulfate aluminum cement, ordinary Portland cement, gypsum, mineral powder, medium sand for construction, a compound water reducing agent, a thickening time control agent and cellulose ether. The grouting material has large fluidity, and the phenomena of segregation and water bleeding of the grouting material mixture are reduced; the grouting material has such early strength that the mounting efficiency and safety of building components can be greatly improved; the grouting material has micro-expansion to ensure the binding force and frictional force transfer axial force effect between the reinforcement, the sleeve and the grouting material; the grouting material has no corrosion to the reinforcement; the product is stable in quality, convenient for storage and transportation, and convenient to use. Apart from the application in connecting the prefabricated assembled concrete component sleeve, the application of the grouting material can be expanded to anchor bolt anchoring, equipment foundation secondary grouting, building strengthening reconstruction projects and the like.
