1983年以来,上海市住宅建设总公司在所属的混凝土制品二厂、四厂的蒸养混凝土生产中,采用浙江省瑞安市桐溪建筑材料厂生产的ST-2复合型糖蜜减水剂(简称糖蜜减水剂),取得了明显的经济效益。生产试用表明,掺入糖蜜减水剂后不仅能减少用水量,节约水泥,改善混凝土和易性,且蒸养后混凝土的早期强度也有明显提高。这对加快预制构件生产周转、降低能耗很有好处。在四年生产实践的基础上,上海市住宅建设总公
Since 1983, Shanghai Housing Construction Corporation adopted ST-2 compound molasses water reducing agent produced by Tongxi Building Material Factory of Rui’an City, Zhejiang Province, in the production of steam curing concrete for the second and fourth concrete plants. Molasses water reducer) has achieved significant economic benefits. Production trials have shown that the addition of molasses water reducer can not only reduce water consumption, save cement, improve concrete workability, but also improve the early strength of concrete after steaming. This is beneficial to speed up production cycle of prefabricated components and reduce energy consumption. Based on the four-year production practice, the general manager of Shanghai Municipal Housing Construction
