The use of fluid catalytic cracking catalyst residue (FC3R) as a cement replacement material has been studied. Four FC3R-blended cements were prepared by the replacement of Portland cement by FC3R in the 6-20% range by mass. Chemical, physical and mechanical properties of the FC3R-blended cements were compared to those of ordinary Portland cement (OPC). Chemical and mechanical tests suggested important pozzolanic activity of FC3R-replacing material. An increase in the compressive strength of the FC3R-blended cements was observed, yielding equal or greater compressive strength than mortars prepared with OPC. (C) 2001 Elsevier Science Ltd.
