In this study, the variation of unit weight and unconfined compressive strength were investigated, calcium carbonate, quicklime, portland cement, 19mm length monofilaments and fibrillated fiber were used as reinforcement materials. And calcium chloride was added to cement and calcium carbonate reinforced soil mixture in order to accelerate setting and hardening speed. It appears that unit weight is highest in calcium carbonate reinforced soil mixture with mixing rate of 9%. According to increasing the amount of fiber in soil mixture, the unit weight decreased. It shows that the more the amount of monofilament fiber is added in soil mixture, the higher the compressive strength is, but the compressive strength is decreased in fibrillated fibrillated fiber added soil mixture with more than 1.0% of mixing rate.
