摘要
利用内蒙古河套灌区粉质粘土拌制水泥土,通过对水泥土试块进行无侧限抗压强度试验,定量分析了水泥掺量和龄期对水泥土强度的影响,并获取了材料应力-应变全过程曲线,探讨了该地区水泥土的变形特性,以期获得适合内蒙古河套地区土质的水泥土配比。试验表明,水泥土的无侧限抗压强度随着龄期的增长呈增大的趋势,养护龄期7~21 d时无侧限抗压强度增长较快;水泥的加入可以有效的改善土体性能,且随水泥掺量的增长呈总体增长趋势。
The main purpose of this study was conducted to quantitatively analyze the effect of cement content and cement age on the strength of cement soil to obtain the material stress-strain curves when the soil cement was made from cement and silty clay in Hetao Irrigation District,Inner Mongolia in order to obtain the cement soil combination suitable for Hetao Irrigation District,Inner Mongolia to provide experimental basis for practical engineerings.Experiment shows that the unconfined compressive strength of cement soil increases with increasing of cement age,and the uncoufined compressive strength increased rapidly from 7 to 21 days;cement can effectively reinforce soil to improve mechanical properties of soil mass,and the intensity increased with the increase of cement content.
