Self-leveling waterproof cement mortar and preparation method thereof
The invention discloses self-leveling waterproof cement mortar. The self-leveling waterproof cement mortar is prepared from the following raw materials in percentage by weight: 30%-50% of limestone machine-made sand, 5%-7% of semi-hydrated gypsum, 13%-14% of heavy calcium powder, 25%-32% of cement and 8%-12% of high-alumina cement, with the balance being an admixture. A preparation method for theself-leveling waterproof cement mortar comprises the following steps: (1) weighing the raw materials; and (2) sequentially mixing the limestone machine-made sand, the cement, the high-alumina cement,the heavy calcium powder, the semi-hydrated gypsum and the additive, and then carrying out stirring at a constant speed to obtain the product. By optimizing the raw material mixing ratio of the mortar, researching the formula of the admixture and replacing quartz sand with the limestone machine-made sand, the produced mortar achieves wear-resistant and floor leveling effects, thereby lowering production cost.
本发明公开了一种自流平水泥防水砂浆，由以下重量百分比的原料制成：石灰石机制砂30％‑50％、半水石膏5％‑7％、重钙粉13％‑14％、水泥25％‑32％、高铝水泥8％‑12％，余量为外加剂；制备方法为：(1)称取各原料；(2)依次将石灰石机制砂、水泥、高铝水泥、重钙粉、半水石膏和外加剂混合，然后匀速搅拌，即得。本发明通过优化砂浆的原料配合比，研究外加剂的配方，使用石灰石机制砂替代石英砂，使产品达到耐磨地平效果，从而降低生产成本。
