Determination of Geotechnical Properties and Stability of Expansive Soil using Fly Ash

This study was conducted to have a detailed analysis of the geotechnical properties expansive soil and fly ash from Sipat thermal power plant. It reported findings laboratory studies on certain common physical properties. The chemical morphology black cotton (BCS) is also determined using scanning electron microscopy X-ray diffraction test. test includes determining specific gravity, particle size distribution, moisture content, standard proctor test, free swell index, Atterberg’s limit. different compositions with ash, yellow soil, moorum, sand are studied. BCS evaluated sand, moorum ash. analyzed details results tests samples. showed that strength inversely proportional; as increases, decreases, vice versa. Fly added 20 80 % by replacing weight. indicated can be stabilized addition limit 10 %.
