摘要
采用室内试验方法,研究了水泥土拌和时的水量对水泥土强度的影响规律,绘制了水泥土无侧限抗压强度与水泥土拌和时的水量关系曲线,获得了水泥掺入比为20%、28 d龄期水泥土无侧抗压强度最优拌合水量。研究表明,拌合水量对水泥土强度的影响是显著的。实际工程中应努力控制水泥土拌合时的水量,以提高水泥土加固的经济技术效益。
By laboratory tests,the effects of mixing-water content on the strength of cement-soil were studied and the curve of unconfined compressive strength of cement-soil has been drawn,and the optimum mixing-water content of cement-soil has been obtained when its cement-admixing-ratio is 20% and its age is 28 d.It is shown that the effects of mixing-water on the strength of cement-soil is significant.So,in actual projects,mixing-water content should be controlled strictly to improve the economic and technological benefits of cement-soil strengthening.
