Improvement Some Soil Properties by Using Lime and Cement at Different Percentages

The Treatment of soils using lime and cement is one of the appropriate techniques that provides solutions for poor geotechnical soils used in road construction. The main objective of this study is to improve some soil properties such as (water content, dry denisity, liquid limit, plastic limit) at different additive percents and two types of additive. In this research soil samples were tested in the standard case without additive and with the additive, two types of additives has been used (cement and lime). The test procedure and test results conducted on original soil and treated soil are presented. Soil-lime mixtures and soil-cement mixture were tested with three percentages of each cement and lime (3 %, 6 %, 9 %) from soil dry weight and one of these percentages is the optimum additive content 6 % cement, 6 % lime. From our result we found that 6 %cement was the optimum additive (percent and type).
