Effect of Fly Ash on Properties of Black Cotton Soil

In India regarding fifty one.8 million hectares of the area unita|acreage|area|expanse|surface area} are lined with Expansive soils (black cotton soil). The Black cotton soils square measure terribly laborious once dry, however lose its strength fully once in wet condition. Expansive soils square measure a worldwide downside that poses many challenges for civil Engineers. Varied ways square measure tailored to enhance the engineering characteristics of expansive soils. The problematic soils square measure either removed and replaced by smart and higher quality material or treated victimization additive. This paper deals with the properties of expansive soils of geographical region, Bharat at varied locations. During this study, black cotton was stable victimization ash (obtained from koradi thermal power plant). Expansive soils were stable with varied proportion of ash i.e. at 0, 10, 20 30, 40 & 50%. Ash possesses no malleability. Malleability index of clay ash mixes decreases with increase in ash content. Therefore addition of ash makes expansive soil less plastic and will increase its workability by mixture reaction and dynamical its grain size. The cosmic radiation values of clay with ash mixes, tested underneath unsoaked & soaked conditions & there results were ascertained, with associate degreealysis of results it's found that the ash features a smart potential to be used as an additive for up the engineering properties of expansive soils.
