| چکیده | ||
| In this article, the effect of liquid Polyester Resin on the strength parameters of clayey sand (SC) was studied. For this purpose, the soil was first characterized and then uniaxial compressive strength and direct shear tests were performed on the specimens without additives and those consolidated with different percentages of polymeric resin at different curing times. In this study, 0.5, 1, 2, 3, and 4 percent of Polyester Resin was added to the clayey sand and the soil properties were studied immediately after mixing and after 1, 3, 7, and 14 days of curing. The changes in the soil strength parameters at different percentages of the polymeric additive were determined at different curing times. Based on the results, the optimum percentage of Polyester Resin was 3% so that further increase in the additive did not increase the soil strength parameters. The effect of curing time in the presence of the polymeric additive indicated that the maximum strength was obtained after 7 days of curing. Increasing Rezin content and curing time led to enhancements in the uniaxial compressive strength, shear strength, cohesion and internal friction of the consolidated specimens. | ||
