Micro-expansion phosphorus slag powder grouting material and using method thereof
The invention belongs to the technical field of building materials, and particularly relates to a micro-expansion phosphorus slag powder grouting material and a using method thereof. The material is prepared from Portland cement, river sand, phosphorous slag powder, slag powder, a phosphorus slag powder activator, calcined magnesium oxide, lipid membrane calcium oxide, polypropylene fibers, wood fibers, modified attapulgite, an antifoaming agent and a water reducing agent. The average particle size of the phosphorous slag powder is in a range of 30-40 mu m, the specific surface area measured through nitrogen absorption is in a range of 350-400 m<2>/kg, the quality factor K is in a range of 1.3-1.4, and the phosphorus slag powder has certain potential pozzolanic activity. The micro-expansion phosphorus slag powder grouting material can be used after directly and evenly mixed with water in a construction site and has the characteristics of good liquidity, good water retention property, certain plastic expansion, high strength, micro-expansion, good crack resistance and the like. The product is applicable to secondary grouting of equipment installation foundations, reinforcement grouting of connecting positions of prefabricated reinforced concrete boards and beam columns and the like.
