| 摘 要： | 本研究通过对掺加混凝土外加剂的水泥土试件进行凝结时间试验、流动度试验，测定混凝土外加剂对水泥土凝结时间及和易性的影响。通过试件立方体抗压强度试验，确定混凝土外加剂对水泥土试件强度的影响。研究表明适当的混凝土外加剂能显著增加水泥土的凝结时间及和易性，且基本对强度没有影响。

| Abstract: | Based on coagulation time and fluidity experiment on cement soil mixed will concrete admixture,the action of concrete admixture to the placeability of cement soil with be proposed.Through non-confined compressive strength experiment on cement soil mixed with concrete dmixture,the affection of the concrete admixture to cement soil strength will be produced.The results indicate that the proper admixture kind could observably improve placeability of cement soil and doesn't influence strength of cement soil. |
