在混凝土中掺用高效能减水剂是制备高强混凝土的一项重要技术途径,为此我们在实验室利用萘系高效能减水剂进行800～1000号高强混凝土的研制工作。试验中所掺用的减水剂为淮南矿务局合成材料厂所产的NF萘系高效能减水剂(下简称为“NF”);水泥为柳州、广州、南京等地所产的“五羊”牌600号硅酸盐水泥(下分别简称为“柳州五羊”、“广州五羊”、“南京五羊”)。配制1000号混凝土时需将南京五羊再磨细至6000厘米~2/克(实际活性为800公
The use of high-efficiency water-reducing agent in concrete is an important technical approach for the preparation of high-strength concrete. For this reason, we used the naphthalene-based high-performance water-reducing agent to develop high-strength concrete No. 800-1000 in the laboratory. The water-reducing agent used in the test was the NF naphthalene-based high-efficiency water-reducing agent (hereinafter referred to as “NF”) produced by the Huainan Mining Bureau’s synthetic material plant; cement was produced in Liuzhou, Guangzhou, and Nanjing. “Wuyang” brand No. 600 Portland cement (hereinafter referred to as “Liuzhou Wuyang”, “Guangzhou Wuyang”, “Nanjing Wuyang”). When preparing No. 1000 concrete, it is necessary to re-smoke Nanjing Wuyang to 6000 cm~2/g (the actual activity is 800
