| Summary: | This paper presents a study on the strength, chloride penetration and resistance to corrosion of SCC made with ternary blend of Portland cement containing ground bagasse ash (BA) and ground rice husk-bark ash (RB). Portland cement type I (CT) was partially replaced by BA and RB at dosage levels of 0%, 10%, 15%, 20%, 30% and 40% by weight of cementitious materials. Test results reveal that the use of BA and RB produced excellent resistance to chloride penetration. The compressive strength of SCC containing RB was higher than that containing only CT and only BA. The concrete containing ternary blends viz., 15% of BA+15% of RB or 20% of BA+20% of RB were better than those containing only 30% of BA or 40% of BA. The compressive strength is a significant factor as it directly affects the chloride penetration of the self-compacting concrete. |
