Influence of Crack Width on Percentage of Chloride Absorption in Concrete

An experimental study was carried out to investigate the effect of crack widths on chloride content due to the penetration of salty water through the crack by using an immersion test that consists of salty water with a concentration of 5%. Eighteen reinforced concrete beams with dimensions (10cm *10cm * 90cm) were made and reinforced with a mild steel bar of 6mm in diameter at the top and the bottom. These specimens were cracked in the bottom due to a pure bending moment in the middle of their span. The results show that chloride content for the cracked specimens increased and overcame the allowable accepted ratio at the Egyptian Code.
