Stabilization of Lateritic Silty Clays with Common Stabilizing Agents
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 3, Issue 4
Abstract
Local common stabilizing agents such as ordinary Portland cement, fly ash and lime were used to stabilize a lateritic silty clay for improved strength and plasticity behaviour of the clay. Various percentage cement content, lime content and fly ash content were studied. Specimens were cured for 7 days; and thereafter unconfined compressive strength (UCS) determined. Test results show that about 8% of Portland cement gave UCS of about 29kg/cm3 which is satisfactory for road use under Nigerian climatic conditions. 8% lime content gave the 7 days peak strength, while the 7 days strength of fly ash contents were significantly more than that without fly ash for fly ash content exceeding 1.5%.
