Abstract: Blast furnace slag (BFS), a by-product of the steel manufacturing industry, being used as an effective partial cement replacement material, has already been proven to improve several performance characteristics of concrete. The reactivity of BFS has been found to depend on the properties of BFS, which varies with the source of BFS, type of raw material used, method and the rate of cooling. In this paper cement replacement level were selected to study the effects of BFS on compressive strength, hydrochloric acid and sulfate resistance in concretes. The number of tests was used to determine the resistance of BFS concrete to sulfate attack. These tests involved immersion in 10% of hydrochloric acid and 15% sodium sulfate solutions.
Furthermore, compressive strength of concrete mixtures that keep in water, hydrochloric acid and sodium sulfate were determined at ages up to 56 and 90 days respectively. The experimental results show that at later ages BFS concrete that keeps in water got closer compressive strength to control concrete.
Keywords: Blast furnace slag; flexural strength; compressive strength; concrete.
