Studies have shown that strength and stiffness of PCC bottom ash mixed with sodium bentonite changes with the increase in the curing period. Researchers have concluded that this change is due to the chemical composition of the bottom ash and bentonite. In order to understand the reasons for the change in characteristics of bottom ash-bentonite mixtures with time, the strength and structural characteristics of bottom ash-bentonite mixtures cured for various periods was evaluated. Results of the strength testing showed increase in strength and stiffness of the mixtures with curing period. The results of structural analysis using environmental scanning electron microscopy show development of fibrous elements which may cause increase in the unconfined compressive strength and stiffness of the mixtures with the curing period. Selected results from this study are presented herein.
