More Information
Summary:The invention discloses superfine sand anti-crack plastering mortar and a preparation method thereof. The anti-crack plastering mortar is prepared from the following raw materials in parts by weight: 15 to 30 parts of cement, 3 to 10 parts of admixture, 7 to 14 parts of water, 43 to 65 parts of superfine sand, 0.25 to 0.60 part of water reducing agent, 0.03 to 0.3 part of water-retaining agent, 0.1 to 1.0 part of rubber powder, 0.05 to 0.2 part of fiber, 1.0 to 5.0 parts of expanding agent and 0 to 0.10 part of water repellent. According to the super-fine sand anti-cracking plastering mortar and the preparation method thereof, aiming at the engineering problems that the super-fine sand plastering mortar is easy to crack, hollow, fall off and the like, the super-fine sand is used as a main raw material, and through the matching of various components, especially the interaction of double-doped fibers and the expanding agent, the anti-cracking performance of the super-fine sand is effectively improved; meanwhile
