Influence of Freeze–Thaw Cycles on Physical and Mechanical Properties of Cement-Treated Silty Sand

The problem of weak ground conditions is currently great interest, as with the rapid development infrastructure, researchers are trying to cope improvement problematic soil properties build structures on it. In cold regions, soils further exacerbated by freeze–thaw cycling. For properties, stabilization method using ordinary Portland Cement (OPC) commonly applied, but it produces a significant amount carbon dioxide emissions. Therefore, purpose this research study present laboratory testing results for evaluation treatment Calcium Sulfoaluminate (CSA) cement that has lesser footprint. On stabilized specimens cured 3, 7, and 14 days subjected cycles, unconfined compressive strength (UCS) ultrasonic pulse velocity (UPV) were performed. Samples prepared at optimum moisture content different content, 3%, 5%, 7%. Applying from UCS test, loss/gain resilient modulus treated obtained. test show values decreased increase cycles. However, in performance can be observed content. Overall, use CSA stabilizer silty sand would useful achieve sufficient subgrade.
