INFLUENCE OF LIME AND WASTE STONE POWDER ON THE PH VALUES AND ATTERBERG LIMITS OF CLAYEY SOIL.

This paper reports an investigation of the influence of waste stone powder and lime on the geotechnical properties of clayey soil. The plasticity and changes in the chemical properties of the soil with pH test when mixed with varying proportions of waste stone powder and lime were investigated. The results show significant reduction in plasticity and increasing in the pH value of clayey soil with increasing amount of waste stone powder and lime. Also there is a decrease in liquid limit and increase in plastic limit with increasing waste stone powder and lime content. The behavior of the geotechnical properties of the clayey soil when blended with waste stone powder and lime indicates that these materials are a good modifier for this soil. [ABSTRACT FROM AUTHOR]
