Abstract—This paper presents the effect of sodium chloride (NaCl) on Steel Fibre Reinforced Blended Cement Concrete (SFRBCC). The SFRBCC was prepared with NaCl concentrations of 0.5, 2, 4, 6, 8, 10, 12, 14, 16 and 20 g/l by adding in deionised water. In addition to this, control specimen was prepared with deionised water (without NaCl) for the purpose of comparison. The setting times and compressive strength were evaluated for 28 and 90 days apart from studying rapid chloride ion permeability. The results show that, as NaCl concentration increases, there is acceleration in initial and final setting of Blended Cement (BC). The compressive strength of SFRBCC increases as the concentration of NaCl goes up at both 28 and 90 days. Compressive strengths of SFRBCC show a significant increase at 12 g/l when compared with the control specimens. It was also observed that chloride ion permeability has decreased with an increase in the concentration of the NaCl. 

Index Terms—NaCl, setting time, SFRBCC, compressive strength, chloride ion permeability
