Effects of Salt Corrosion and Freeze-Thaw Cycle on Rubberized Cement-Soil
In order to improve salt corrosion and frost resistance of cement-soil, the waste tire rubber powder was mixed into cement-soil to form rubberized cement-soil. In the salt corrosion and freeze - thaw cycle (SCFT) conditions, compressive strength of rubberized cement-soil increases first and then decreases with rubber content increasing. The more numbers of SCFT cycles, the more strength slip increases. But in high concentration conditions, the strength of rubberized cement-soil with 5%-10% rubber content reduces. With the solution concentration or SCFT cycles number increasing, peak stress of rubberized cement-soil and common cement-soil gradually reduces, but strength slip of rubberized cement-soil is lower than of cement-soil. Studies indicate that the performance of rubberized cement-soil surpasses common cement-soil decided by the relationship between rubberized cement-soil skeleton elastic behavior and coupling expansive force.
