High belite sulphoaluminate cement concrete admixture
The invention relates to a high belite sulphoaluminate cement concrete admixture. The high-belite sulphoaluminate cement concrete admixture is prepared from the following components in percentage by mass: 20%-50% of a special water reducing agent A for high-belite sulphoaluminate cement concrete, 15%-30% of a retarder, 0-5% of a viscosity regulator, 0-2% of an air entraining agent and 30%-65% of ground stone powder. Wherein the sum of the components is 100%. And drying the special water reducing agent A until the water content is less than or equal to 1%, and uniformly mixing the special waterreducing agent A with a retarder, a viscosity regulator, an air entraining agent and ground stone powder in a mixer. The invention also provides a preparation method of the special water reducing agent A. The method improves the workability of the high-belite sulphoaluminate cement concrete, reduces the slump loss of the concrete, has the composite effects of water reduction, delayed coagulation,early strength and the like, and is simple in process, low in production cost and suitable for industrial production.
一种高贝利特硫铝酸盐水泥混凝土外加剂，它是由高贝利特硫铝酸盐水泥混凝土专用减水剂A、缓凝剂、粘度调节剂、引气剂、磨细石粉制成，各组分质量百分比为：所述专用减水剂A 20％～50％，缓凝剂15％～30％，粘度调节剂0～5％，引气剂0～2％，磨细石粉30％～65％；上述各组分之和为100％；将所述专用减水剂A干燥至含水率≤1％，然后与缓凝剂、粘度调节剂、引气剂、磨细石粉放入混料机内混合均匀即制。本发明还提供了所述专用减水剂A的制备方法。本发明改善了高贝利特硫铝酸盐水泥混凝土的和易性，减少了混凝土坍落度损失，具有减水、缓凝、早强等复合效果，并且工艺简单，生产成本低，适合工业化生产。
