Preparation method of polymer cement mortar with high crack resistance
The invention discloses a preparation method of polymer cement mortar with high crack resistance. According to the preparation method of the high-crack-resistance polymer cement mortar, the high-crack-resistance polymer cement mortar is prepared from quartz sand, composite coal ash, cement, waste rubber powder, a rubber powder modifier, trilobal polypropylene fibers, basalt short fibers, a capillary crystalline admixture, an organic silicon waterproof agent, an adhesive and a water-retaining agent. The basalt fiber is small in heat conductivity coefficient, high in elastic modulus, high in tensile strength and good in dispersity; the added trilobal polypropylene fibers increase the tensile strength of cement and can disperse and transfer stress on mortar, so that the tensile strength and impact toughness of the mortar are improved, and the added basalt short fibers are uniformly distributed in the mortar, so that the compactness of the mortar is increased, and the crack resistance of the cement mortar is improved. The cement mortar prepared by the method is more suitable for people to use.
本发明公开了一种高抗裂强度聚合物水泥砂浆的制备方法。本发明中，所述高抗裂强度聚合物水泥砂浆的制备方法包括：石英砂、复合煤灰、水泥、废橡胶粉、橡胶粉改性剂、三叶型聚丙烯纤维、玄武岩短纤维、渗透结晶型外加剂、有机硅防水剂、粘接剂、保水剂，玄武岩纤维具有导热系数小、弹性模量高、拉伸强度大、分散性好；加入的三叶型聚丙烯纤维、增加了水泥抗拉强度，能够分散和传递砂浆受到的应力，从而提高砂浆的抗拉强度和抗冲击韧性，同时加入的玄武岩短纤维在砂浆中分布均匀，增加了砂浆的密实性，增加了该水泥砂浆的抗裂能力，使得该方法制得的水泥砂浆更适合人们使用。
