Influence of Coal Ash on Strength Behavior of Silty Sand
Keywords:
Coal ash, Unconfined compressive strength (UCS) and California bearing ratio (CBR)Abstract
The present study intends to improve the properties of local soil by mixing it with waste material coal ash. This coal ash is a byproduct generated from combustion of coal in thermal power plants. Finding worthwhile applications in the fields of construction makes effective use of this pollutant - coal ash. The present investigation describes the behavioral aspect of silty sand mixed with coal ash thereby improves the load bearing capacity of the soil. Investigation of results revealed that as the percentage of coal ash was increased from 10 % to 50 % there was improvement in UCS and CBR strength of subgrade soil thus improving it for bearing more load in foundation structures of pavements.
