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。

The influence of water content on the strength of cement soil was studied by indoor test. The curves of unconfined compressive strength of cement soil and the water content of cement mixed with soil were drawn. The results showed that the cement incorporation ratio was 20% , 28 d age cement soil unconfined compressive strength of the optimal mixing water. The results show that the influence of mixing amount of water on the strength of cement soil is significant. In the actual project, efforts should be made to control the amount of water during the mixing of cement and soil to improve the economic and technical benefits of cement-soil consolidation.
