Abstract

M-sand can be used as an inexpensive substitute for river sand due to insufficient natural resources. Reinforcement corrosion is a main factor affecting the durability of concrete. In this paper, the impact of fibers and ground granulator blast furnace slag (GGBFS) on corrosion resistance of concrete with M-Sand as fine aggregate was studied. Based on the experimental observations, the influence of polypropylene fibre added in various percentages in concrete with 40% GGBFS and M-sand on the corrosion resistive properties was systematically analyzed after curing period of 28, 56 and 90 days. It was revealed that the incorporation of M-sand, GGBFS and polypropylene fibres in concrete contributed to a significant improvement in strength and corrosion resistive properties.
