ENZYME ENHANCED STABILIZATION OF SOIL AND FLY ASH
The purpose of this research was to determine if enzymes could be utilised to increase the strength and stability of soil mixed with fly ash. Samples were prepared with and without the enzyme by varying the percentages of fly ash in the soil-fly ash mixture and subjected to unconfined compression test, freeze thaw test and compaction test. The results indicated that addition of very small amount of enzyme (about 5%) increased the unconfined compression strength significantly. The UC strengths of enzyme stabilized soil-fly ash mixture was found to be higher than the UC strengths of lime stabilized soil and gained higher strengths earlier. Enzyme stabilized soil-fly ash mixture was found to be as stable as the lime stabilized soil-fly ash mixture under freeze- thaw cycles. No change in the compaction characteristics of soil-fly ash mixture was observed because of the enzyme. For the covering abstract see IRRD 863991.
