Experimental study on effect of ground granulated blast furnace slag of strength and durability of sand concrete

Abstract

Concrete used for building structures in the marine environment requires a high level of durability, and as such an effective method to improve the level is the use of ground granulated blast furnace slag (GGBFS). The paper presents an experimental study on the effect of the replacement cement by 20%, 30%, 40%, 50% GGBFS on workability, mechanical properties and durability of sand concrete (SC). The results show SC containing 20% GGBFS had the highest compressive strength, splitting tensile strength, elastic modulus and abrasion resistance. The lowest chloride penetration corresponded to SC containing 30% GGBFS.
