Study of Engineering Properties of Expansive Soil Stabilized with Quarry Dust and Fly Ash
The expansive soils are problematic as a foundation soil and due to high swelling and shrinkage, these soils poses lots of problems for the structures found on them. In reference to that the fly ash is a waste product from thermal plant, which uses coal as fuel and quarry dust is a by-product of crusher units used for stone cutting, etc., and when mixed with expansive soil separately they found to have improved the swelling and shrinking behavior of the soil. The present paper describes a study carried out to check the improvements in the properties of expansive soil with mixing of both fly ash and stone quarry in equal proportion and varying the overall percentage. There are some conclusions established based on the experimental observation, such as (a) the liquid limit and plastic limit values go on increasing with increase in percentage of fly ash–quarry dust mix, (b) the optimum moisture content (OMC) goes on decreasing with an increase in percentage of the mix, (c) the California bearing ratio (CBR) values increases with increase in percentage mix, although percentagewise it is quite significant, and (d) the free swell index (FSI) decreases with increase in mix from 10 to 50%, by 20%.
