ABSTRACT
The samples were divided into four groups, coded as A, B, C and D. Group A was the control blend of limestone only. Group B had 30% bottom ash and 70% limestone. Group C had 50% of each of IBAA and limestone and group D had 80% IBAA. The replacement of limestone with IBAA in the various blends followed a simple approach based on matching particle size distributions and is explained elsewhere (Hassan & Khalid, 2007).
