Abstract

This paper presents a study of the compressive strength, chloride penetration and corrosion of self-compacting concrete (SCC) containing original fly ash (FA) and ground calcium carbide residue (CB). CB, FA and Portland cement type 1 (CT) were used as a ternary blends system in producing self-compacting concrete (SCC). Water to binder ratio (W/B) with constant of 0.48 was used in this work. In ternary blend system, strength activity index of concrete is high at 79-96% in comparison with the CT concrete at 28 days. The chloride penetration and corrosion of concrete with 15% of FA+10% of CB, 15% of FA+15% of CB and 15% of FA+20% of CB is high in comparison with the concrete mixes at 15% of FA by weight of cementitious materials.
