This paper aims to study the effect of using synthetic zeolite on chloride resistance and compressive strength of concrete. In this paper, Portland cement type I and synthetic zeolite were used as cementitious materials. The binder content in concrete was replaced by synthetic zeolite at 0.01, 0.03, 0.05 and 0.10 of synthetic zeolite to binder ratios. Water to binder ratios were kept at 0.50 and 0.60. The rapid chloride penetration and compressive strength of concrete were performed at 7, 28, 56 and 91 days of curing time. Chloride penetration by bulk diffusion was tested after 28 days of water curing and immersed in 5.0% chloride concentration for 28 days. The study results showed that concretes with synthetic zeolite had better chloride resistance than cement-only concrete at all water to binder ratios. Concrete with 0.03 of synthetic zeolite to binder ratio had the best chloride resistance. This property is because silica and alumina of synthetic zeolite can react with calcium hydroxide to form CSH and CAH, and the small particles of synthetic zeolite can fill the void in concrete. But, concretes with synthetic zeolite had lower compressive strength than cement-only concrete because cement content was reduced by using synthetic zeolite in concrete, resulting in decreased compressive strength. Moreover, concrete with 0.50 of water to binder ratio had higher chloride resistance and compressive strength than concrete with 0.60 of water to binder ratio.
