The invention discloses cement-based self-leveling mortar containing spherical special aggregate and a preparation method of the cement-based self-leveling mortar, relates to the technical field of mortar. The following scheme is provided aiming at the problem of poor working performance of the existing self-leveling mortar, wherein the cement-based self-leveling mortar comprises, by mass, 9.0-14.0% of Portland cement, 18.5-23.5% of aluminate cement, 5.5%-9.5% of gypsum, 29.5%-34.5% of the spherical special aggregate, 14.5%-19.5% of natural aggregate, 11.0%-15.0% of heavy calcium powder and 2.0%-3.5% of an additive. Due to the ball effect of the spherical aggregate and the effect of reducing water consumption, the spherical aggregate has good flowability, volume stability, compression resistance and breaking strength, and can generate the appearance effect of uniform and uniform color.
本发明公开了一种含有球形特种骨料的水泥基自流平砂浆及其制备方法，涉及砂浆技术领域，针对现有的自流平砂浆工作性能不佳的问题，现提出如下方案，其包括以下各组分的质量百分比：硅酸盐水泥：9.0‑14.0％，铝酸盐水泥；18.5‑23.5％，石膏：5.5‑9.5％，球形特种骨料：29.5‑34.5％，天然骨料：14.5‑19.5％，重钙粉：11.0‑15.0％，外加剂2.0％‑3.5％。本发明由于球形骨料的滚珠效应和降低用水量作用，其具有良好的流动性、体积稳定性和抗压、抗折强度，并会产生均匀、统一颜色的表观效果。
