摘要:
通过开展一系列水泥固化土的无侧限抗压试验和流动度试验,探讨初始含水率与养护龄期对水泥固化土的强度与流动性的影响规律与作用机理。结果表明:水泥固化土的应力应变关系呈现应变软化特性,固化土的强度随着含水率的增加而减少,随着养护龄期的增加而增大。固化土的流动值随着初始含水率的增大而增加,整体表现为低流动性。
Abstract:
By carrying out a series of unconfined compressive strength and fluidity tests of cement solidified soil, the influence law and mechanism of initial moisture content and curing age on the strength and fluidity of cement solidified soil were discussed. The results show that the stress- strain of cement solidified soil presents strain softening characteristics. The strength of cement solidified soil decreases with the increase of water content and increases with the increase of curing age. The flow value of solidified soil increases with the increase of initial moisture content, and the overall performance is low fluidity.
