ABSTRACT
Concrete made from ordinary Portland cement continues to be used as the main construction materials because of its durability and strength characteristics in service life. But the contrary becomes the case when such concrete is exposed to aggressive environment created by the prevalence of chloride ions that are common in marine/coastal environment characterized by temperature extremes, that is peculiar to Nigeria. Hot marine and coastal environment, constitute an aggressive environment that has been found to be deleterious to the strength and durability characteristics of concrete, thus causing premature deterioration of concrete structures. Research works to reverse this trend go on continuously. This paper presents one of such works which investigates the effect of partial replacement of cement with slag on chloride permeability of concrete cured at elevated temperatures. It was found out that partial replacement of cement with slag increases the resistance of concrete to chloride penetration
