Enhanced crack-resistant cement floor material
The invention discloses an enhanced crack-resistant cement floor material. The problems of low tension-compression ratio, large drying shrinkage deformation and poor crack resistance of cement mortars in the prior art are mainly solved in the invention. The material is composed of 120-130 parts of cement, 500-550 parts of river sand, 80-90 parts of water, 35-40 parts of enhanced fiber, 5-6 parts of an HSB aliphatic efficient water reducer, and 2-3 parts of a propylene organic thickening agent, and the enhanced fiber is obtained by mixing brucite fiber with polyacrylonitrile fiber. The enhanced crack-resistant cement floor material has the advantages of good toughness, uniformity and difficult cracking.
