| Soil improvement involves a variety of approaches. Among them, addition of specific materials has been widely adopted in the literature. Colossal numbers of worn tires are released in the environment every year. It will cause serious environmental issues. Moreover, cement production process causes detrimental consequences for environment, but it still is considered as one of the main options in construction projects. So, the main purpose of this research is to find suitable alternative methods to decrease cement usage. In this paper the effect of adding zeolite and waste rubber powder on unconfined compression strength (UCS) of soil were investigated. Two types of sandy soil were adopted in this study, SP and SW soil. In order to improve these two types of soils, 4% by weight cement, 0, 0.25, 0.5 and 0.75% rubber powder and 0, 10, 30 and 50% zeolite replacement with cement during curing period of 7, 14 and 28 days were considered. According to the compaction test results, by increasing the percentage of rubber powder, the maximum dry density and the optimal moisture content of both type of soils decreases. However, with zeolite addition, the maximum dry density of both type of soils has decreased and value of optimum moisture has increased. The optimum percentage of zeolite and rubber powder in SW soil was 30% and 0.5% respectively, while in SP soil these amounts were 10% and 0.25% respectively. | ||
