Abstract
The invention relates to the field of building materials and particularly relates to cement mortar which is used for constructional engineering and has an anti-cracking performance and a preparation method thereof. The cement mortar is characterized by being composed of following components according to following ratios: 60-80 parts of perlite, 30-40 parts of cement, 5-8 parts of kaolin, 1-5 parts of bentonite, 1-5 parts of sepiolite, 5-10 parts of fibers, 20-40 parts of river sand and 70-80 parts of water. The preparation method comprises the steps that all the components are taken according to the ratios; the cement, the fibers and the river sand are sufficiently mixed; then the residual components are sequentially added and are continuously agitated to form the cement mortar. Compared with the prior art, the characteristics that the perlite has light weight, low heat conductivity coefficient, corrosion resistance, freeze thawing resistance, small drying shrinkage, small water immersing linear deformation rate and the like are utilized so that the anti-cracking performance of the cement mortar is improved; meanwhile, the components including the kaolin, the bentonite, the sepiolite and the like are utilized to adjust the viscosity of the mortar, so that the cement mortar has the obvious characteristics of strong adhesive force, good anti-cracking performance and the like.
