Cyclic Undrained Behavior and Liquefaction Potential of Sand Treated with Chemical Grouts and Microfine Cement (MC-500)

Abstract

Abstract The effect of chemical grouting on the response of sand to monotonic and cyclic load is evaluated. Triaxial compression (CD and CU) tests and cyclic triaxial tests are performed to evaluate the effect of chemical grouting on the potential for liquefaction flow failure, initial liquefaction, and 5% cyclic mobility. The influence of selected material parameters and test variables (i.e., grout mixture proportions, grout type and curing time, sand void ratio, cyclic stress ratio, number of cycles) on the behavior of chemically grouted sand is examined. The effect of chemical grouting on the increase in resistance to liquefaction is quantified.
