Study on the strength characteristics of solidified marine clay
A new solidified agent for beach marine clay was designed,and the strength of so-lidified marine clay were studied.The initial proportion of curing agent was designed based on the principle of orthogonal test.Through unconfined compressive strength test and dry-wet cycle test,the effects of curing age,dry and wet cycle times and the proportion of curing agent on the strength of solidified marine clay were studied,and the optimal proportion of curing agent and its curing effect were obtained.It is found that the early strength of solidi-fied marine clay can reach more than 1 MPa,and the long-term strength can reach about 2.6 MPa,and it has good durability against sulfate attack.The curing agent designed in this study can reduce the moisture content and complete the initial hardening of marine clay in a short time.Meanwhile,it also has sufficient long-term strength and the durability to resist sulfate attack and thus can meet the needs of offshore engineering.
