Expansive Soil Stabilization Using Marble Dust and Bagasse Ash

R. Ali [27] | H. Khan [5] | A. A. Shah

Abstract: This research is an attempt to investigate the effect of marble dust and bagasse ash on the stabilization of expansive soils. Expansive soils are always characterized by their high expansion; high moisture content; high compressibility; high shrinkage on drying along with wide polygonal cracks and sufficient swelling on wetting. Expansive soils (problematic soil) are present in different parts of the world and extensively found in many locations particularly in Pakistan. In KPK province we select five different sites and collect soil sample and determine their index properties. While selecting sites we visually inspect the soil and collect soil sample from area having wide cracks in soil in dry condition. From the index properties of all the soil samples; district Bannu soil were classified as expansive soil having liquid limit greater than 50 % and plasticity index greater than 30 %. Currently different techniques are in use for improvements of expansive soil but most of them are uneconomical. For expansive soil improvement we use marble dust and baggase ash which are already burden on our natural environment. Utilizing these wastes for the improvement of expansive soil will be the best alternative. Different lab tests on expansive soil without the addition of these waste and with the addition of these waste were performed and their effect on swelling and other properties were determined. Finally; marble dust and baggase ash can be utilized to treat and stabilize the expansive soil as economical alternative to Portland cement and other (expensive) chemical stabilizers. The use of baggase ash and marble dust for stabilization applications is an economical and environmental solution of the problems associated with its disposal process.
