Full-machine-made sand waterproof cement-based self-leveling mortar and preparation method thereof
The invention belongs to the field of building materials, and particularly relates to full-machine-made sand waterproof cement-based self-leveling mortar and a preparation method thereof. The all-machine-made sand waterproof cement-based self-leveling mortar is prepared from the following raw materials: Portland cement, sulphoaluminate cement, anhydrite, ground calcium carbonate, machine-made sand, redispersible latex powder, a water reducing agent, a water repellent, an early strength agent, a retarder, cellulose ether, polypropylene fibers, a defoaming agent and a suspension stabilizer. The all-machine-made sand waterproof cement-based self-leveling mortar is scientific and reasonable in raw material and dosage ratio, and after repeated verification, the selected raw materials and dosage enable the self-leveling mortar to achieve excellent effects in indexes such as initial fluidity, 20min fluidity, fluidity loss rate, flexural and compressive strength, waterproof performance and the like; the construction and mechanical property requirements can be met.
本发明属于建筑材料领域，具体涉及一种全机制砂防水型水泥基自流平砂浆及其制备方法。所述全机制砂防水型水泥基自流平砂浆包括如下原料：硅酸盐水泥、硫铝酸盐水泥、硬石膏、重钙、机制砂、再分散乳胶粉、减水剂、憎水剂、早强剂、缓凝剂、纤维素醚、聚丙烯纤维、消泡剂和悬浮稳定剂。本发明所述的全机制砂防水型水泥基自流平砂浆，各原料及用量配比科学合理，经反复验证后，所选原料及用量能使自流平砂浆在初始流动度、20min流动度、流动度损失率、抗折抗压强度、防水性能等指标达到优异的效果，能够满足施工与力学性能要求。
