【摘要】 在分析水泥水化作用理论需水量的基础上,采用室内试验方法,研究了水泥土拌合水量对水泥土力学性能的影响规律,研究了拌合水量与水泥土无侧限抗压强度及其抗剪强度指标内摩擦角、粘聚力之间的相互关系,获得了水泥掺入比为20%、28d龄期水泥土最优拌合水量。对于湖南衡阳的饱和软粘土,水泥掺入比为20%、28d龄期水泥土最优拌合水量约为28%。实际工程中应采取措施将水泥土拌合时的水量控制在最优拌合水量附近,以提高水泥土加固的经济技术效益。更多还原

【Abstract】 Based on the study of the theoretical water requirement about cement hydration,indoor test methods were adopted.The relation of the cement-soil mixing-water amount with the mechanical properties of the cement-soil and the impact of the mixing-water amount on the unconfined compressive strength and shear strength of the cement-soil were studied,and the optimal mixing-water amount of the cement-soil was achieved when its cement blend ratio is 20% and its age is 28 days.As to the saturated soft clay in Hengyang,Hunan,its optimal mixing-water amount of cement-soil is about 28% when its cement blend ratio is 20% and its age is 28 days.In actual project,in order to enhance the economic and technological benefits of the cement-soil reinforcement,measures should be taken to control the mixing-water amount near its optimal mixing-water amount.更多还原
