Abstract
Today, the use of fiber and nanoscale materials in soil stabilization has been considered according to positive effects on problematic soils. For this purpose, the effect of carbon fiber, nanoclay and lime separately and their mixture (with equal ratio) on the behavior of gypsum clay soils have been investigated in this study. In order to accurately determine the effect of additives on the soil, suitable tests were performed such as atberberg tests, density, direct shear test and consolidation on the soil with mixed percentages of 2, 4, 6, 8% fibers, nanoclay and lime at the duration of treatment 7 and 28 days old. According to the results of the research, the optimum percentage of lime, fiber and mixture of fiber lime were 6% and for nono clay was 4%, and the duration of treatment had significant effect on the behavior of improved soils with these additives. Also, the results show that with adding lime and carbon fiber separately to the native soil, consolidation settlement decreased. But the settlement increases up to 2% of nanoclay and also, mixture of carbon fiber, lime and nanoclay and with increasing of these materials more than 2 percent, decreasing trend is observed.
