水泥黄土的工程特性探讨

主要探讨了水泥黄土的工程性质与掺合比的关系,以及含水量对强度的影响问题,通过试验表明:水泥黄土的最优含水量随着水泥掺入量的增大而增大;最大干密度随着水泥掺入量的增大而减小,但是变化量均较小,水泥黄土强度随着龄期的增长而增大,在前期含水量对强度的影响不大,但在后期含水量越接近水泥黄土的最优含水量其强度越大,从总体上来说强度的增长是越来越慢的。

Research on the properties of the cement-loess

This paper mainly discusses the properties of cement-loess with different blending ratio and the how water content effects the strength.It comes to some conclusions: the optimum water content of cement-loess enlarges with the enlargement of cement blending ratio,the largest dry density reduces with the enlargement of cement blending ratio,but the charge is not big.What’s more,the strength of cement-loess get higher with the enlargement of maintenance time.During the earlier time of maintenance time,water content has less effect to the strength.The more close to the optimum water content,the higher the cement-loess is,at the later maintenance time.In the whole,the strength enlargement becomes slower and slower.
