摘　　要：通过选用柠檬酸、白糖、葡萄糖酸钠为矿渣硅酸盐水泥的缓凝剂,测定了不同温度下水泥的凝结时间,分析了温度对混凝土缓凝剂最优掺量的影响规律。通过选用木质素磺酸钙为矿渣硅酸盐水泥减水剂,讨论了减水剂掺量对减水率的影响。The cement setting time at different temperatures has been measured through choosing citric acid, sugar and sodium gluconate as the retarders of iron portland cement. And the influence rule of temperature to the optimal amount of concrete retarder has been analyzed. Then, calcium lignosulfonate has been selected for water-reducing agent of iron portland cement and the impact of the amount to water-reducing rate has also been discussed in this paper.
