Preparation method for cement mortar for anti-crack cement floor
The invention discloses a preparation method for cement mortar for an anti-crack cement floor and mainly solves the problems that the cement mortar is low in tension-compression ratio, large in dry shrinkage deformation and poor in crack resistance in the prior art. The preparation method comprises the following steps: (1) fully mixing cement, reinforced fibers, river sand and 1/3-1/2 of an organic thickening agent so as to obtain a mixture; (2) fully and uniformly mixing an HSB aliphatic efficient water-reducing agent and water, adding liquid obtained after uniform mixing into the mixture and uniformly stirring so as to obtain a cement mortar intermediate; (3) uniformly stirring the rest organic thickening agent in the cement mortar intermediate, and stirring the cement mortar intermediate constantly during the adding process of the organic thickening agent so as to obtain the cement mortar after adding. The cement mortar prepared through the preparation method has the advantages of good toughness, uniformity and low possibility of cracking.
