Enhancing the Clay Soil Characteristics using Copper Slag Stabilization
Journal Title: JOURNAL OF ADVANCES IN CHEMISTRY - Year 2016, Vol 12, Issue 26
Abstract
This paper investigates the feasibility of utilizing the industrial by-product copper slag as a stabilizer in the expansion soil where swelling characteristics are higher and causes severe damage to the structure and road pavement. The study has been extended to identify the adequate percentage of copper slag additive in the strength enhancement of clay soil. Three different fractions were experimented in the current process of stabilization viz. 10%, 20% and 30% of copper slag and accordingly the results of Maximum Dry Density (MDD), Optimum Moisture Content (OMC) and California Bearing Ratio (CBR) are compared with the ASTM and Indian standards for the design requirements of sub-grade for the flexible pavement. The results show that the combination of 70% clay soil and 30% copper slag is the compatible stabilization ratio which increases all the desirable characteristics of sub-grade requirements.
