This paper presents an experimental investigation on the behavior of binary and ternary blended cements self-compacting concretes exposed to different acid environments, namely, sulfuric acid and hydrochloric acid solutions for different periods. Two types of mineral additives were used in this investigation; silica fume and fly ash. The percentage of addition of silica fume and fly ash were determined to obtain self-compacting concrete with the highest 28-day compressive strength. Compressive strength, weight change and water absorption of concrete were determined after exposure to acidic environments and compared with those of the specimens immersed in tap water. The scanning electron microscope test was carried out to determine the effect of acidic environments on the microstructure of the concrete. The investigation indicated that in general the ternary blended concrete had better acid resistance than the plain and binary blended cement concretes.
