Impermeable and anti-crack premixed mortar and preparation method thereof
The invention discloses anti-seepage and anti-cracking premixed mortar and a preparation method thereof, and belongs to the technical field of building mortar materials, the anti-seepage and anti-cracking premixed mortar comprises the following raw materials by mass: 40-50 parts of cement, 30-40 parts of river sand, 10-15 parts of composite blast furnace slag, 50-60 parts of basalt gravel, 10-20 parts of fly ash, 8-12 parts of mineral powder, 8-10 parts of an anti-seepage and anti-cracking agent, 1-3 parts of a water reducer and 30-40 parts of water. Pores of the mortar are filled with the polyvinyl alcohol along with the small-size eggshell powder, so that the compactness of the mortar is improved, and the impermeability of the mortar is enhanced; negative charges carried by the sulfonated lignin can be combined with positive charges carried by mortar particles and can be adsorbed on the surfaces of the mortar particles, so that the eggshell powder loaded with polyvinyl alcohol is tightly combined with the mortar, and the compactness of the mortar is improved. And the fish scale powder can improve the energy required by crack propagation, reduce the development of micro-cracks and enhance the crack resistance of the mortar.
本发明公开了一种抗渗抗裂预拌砂浆及其制备方法，属于建筑砂浆材料技术领域，包括以下质量份原料：水泥40‑50份、河沙30‑40份、复合高炉矿渣10‑15份、玄武岩碎石50‑60份、粉煤灰10‑20份、矿粉8‑12份、抗渗、抗裂剂8‑10份、减水剂1‑3份和水30‑40份。聚乙烯醇伴随小尺寸蛋壳粉填充至砂浆的孔隙中，提高砂浆的致密性，从而增强砂浆的抗渗性；磺酸化木质素携带的负电荷能够与砂浆颗粒携带的正电荷结合，能够吸附在砂浆颗粒表面，进而使得负载聚乙烯醇的蛋壳粉与砂浆紧密结合，提高砂浆的密实度。鱼鳞粉可提高裂缝扩展所需能量，减少微裂缝的发展，增强砂浆的抗裂性能。
