Anti-crack mortar and preparation method therefor
The present invention relates to an anti-crack mortar and a preparation method therefor. The anti-crack mortar comprises the following components by weight percentage: 28-30% of cement, 10-6% of coal ash or 5%-10% of glass powder, 5% of heavy calcium, 57-59% of medium-coarse sand, 0.3% of HPMC, 1.5-2% of latex powder, 0.2% of water Shen agent, 0.3% of polypropylene fiber and 0-0.3% of other additives, wherein the HPMC is hydroxypropyl methylcellulose with viscosity being 100,000. According to the present invention, waste coal ash (glass powder) is used, so as to protect the environment and save energy; The mortar has good fluidity and water retention, thereby facilitating mixing. The hardened mortar has high hardness and high strength, and is non-toxic and high in stability.
