Early-strength Portland cement-based self-leveling mortar and preparation method thereof
The invention discloses early-strength Portland cement-based self-leveling mortar which is characterized by comprising a liquid component A and a powder component B, the mass ratio of the liquid component A to the powder component B is (0.012-0.018); the liquid component A comprises the following components: 1.2 to 1.5 percent of water reducing agent, 1.0 to 3.2 per mill of defoaming agent and 8 to 16 per mill of polymer emulsion; the powder component B is prepared from the following components: 25 to 35 percent of ordinary Portland cement, 4 to 10 percent of superfine Portland cement, 5 to 12 percent of fine-grained slag powder, 1 to 5 percent of gypsum, 50 to 60 percent of fine aggregate, 10 to 15 percent of 400-mesh heavy calcium powder, 0.05 to 1.85 percent of a water-retaining agent, 0.8 to 1.8 percent of an early strength agent, 0.05 to 1.25 percent of a shrinkage reducing agent and 1.5 to 5.0 percent of an expanding agent. The prepared flat mortar is smooth and flat in surface, good in uniformity and stable in performance.
本发明公开了一种早强型硅酸盐水泥基自流平砂浆，其特征在于，包括液体组分A和粉料组分B；所述液体组分A和粉体组分B的质量比为：0.012~0.018；所述液体组分A包括以下成分：减水剂1.2~1.5%、消泡剂1.0~3.2‰、聚合物乳液8~16‰；所述粉体组分B包括以下成分组分：普通硅酸盐水泥25~35%、超细硅酸盐水泥4~10%、细粒度矿渣粉5~12%、石膏1~5%、细集料50~60%、400目重钙粉10~15%、保水剂0.5~1.85‰、早强剂0.8~1.8%、减缩剂0.5~1.25‰、膨胀剂1.5~5.0%。本发明所制成的平砂浆，表面光滑平整，均匀性好，性能稳定。
