Investigation of reinforced concrete resistance to chlorides

    Abstract

    Chloride penetration is responsible for deterioration of concrete and the reinforcing steel rods. In this paper the deterioration of concrete due to chloride penetration was studied. As part of durability study, concrete with different water to cement (w/c) ratios were investigated by immersing specimens in natural sea water for periods up to 4 months. Immersed test specimens underwent uniaxial compressive test to ascertain concrete's strength and were inspected under electron microscope to determine the effect of various w/c concrete matrix under chloride attack. Test results indicate that concrete mix with high w/c were subjected to a greater gradient of chloride attack and exhibited the most reduction in compressive strength. Consequently it is recommended that low w/c mixture is required to improve concrete durability as it influences the porosity and pore-size distribution in the concrete.
