| Abstract |
The rate of deterioration in reinforced concrete structures built with Portland cement has increased over the period caused by various factors such as sea wind and environmental pollution. These environmental factors accelerate the corrosion of the reinforcement and the products that formed from the corrosion process generate expansive pressure within the concrete that cause the cracks or delamination on the surface of the concrete. The accelerated corrosion of the reinforcement cause problems in durability of the reinforced concrete by reducing effective cross section of the concrete, reducing cross section of the reinforcement which results in reduced mechanical efficiency of the reinforcement, and reducing internal forces which is caused by reduced rebar/concrete adhesive forces. This research studies the durability of the seven testing samples with variable strength of the concrete and level of corrosion of the reinforcement for reinforced concrete column member and summarizes the results to provide the fundamental basis for evaluating the durability. |
