Effects of Cement and Additive on Strength of Soil-cement with High Salt

Three types of cements, which were used to reinforce soft soil with high salt at Lianyungang area, were mixed with soft soil to research their adaptability for reinforcing soft soil with high salt, and the effects on soil cement£§s strength were analyzed through the change of cement ratio and additive. According to the requirement, the corresponding soil-cement samples were obtained, and their unconfined compressive strength of the samples at 7 d, 28 d and 90 d curing age were tested through laboratory orthogonal test. The research results can account for the effects of cement-type, cement ratio and additive on the strength of soil-cement with high salt, which provides a beneficial reference for solving the crucial technical problem caused by soft ground with high salt when reinforced by soil-cement.
