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.
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。
The results show that composite inhibitors have excellent corrosion inhibition efficiency and won't give bad effect on cement setting time , flexural strength and compressive strength.
结果表明，三元复合缓蚀剂具有良好的缓蚀效果且不会对水泥凝结时间和强度产生不良影响。
The need for cement retardation increases with depth due to the greater time required to complete the cementing operation and the effect of increased temperature on the cement-setting process.
深度越大，为完成注水泥作业所需的时间越长，而且由于升高的温度对水泥浆凝固过程的影响，因而对水泥浆缓凝的需求也越高。
