Steel corrosion is an important factor in the degradation of reinforced concrete buildings. ASTM C 876-91 is a standard test method that can be used in both field and laboratory settings to measure the half-cell potentials of uncoated reinforcing steel in concrete. This measurement can help determine the level of corrosion activity in the steel. By using electrical circuitry and potential difference, this test method can provide insight into the rate of corrosion and the overall durability of reinforced concrete. As per this research, we focus to evaluate the impact of acid exposure in the durability of the reinforced concrete (RCC) through experimental analysis. Our approach involves the preparation of concrete cubes with dimensions of 70.5mm x 70.5mm x 70.5mm using M30 grade concrete as per the mix design. A total of 24 cubes are cast for testing purposes. To initiate the experimentation, these cubes are initially cured by immersing them in water for a period of 28 days. Subsequently, the cured cubes are subjected to immersion and spraying with various concentrations of acids, namely hydrochloric acid, sulfuric acid, and sodium chloride, each at a 3% concentration. This exposure lasts for 56 days, allowing for the evaluation of the effects of acid exposure on the durability of the RCC structures. To determine the durability of the RCC structure, the cured cubes are tested using a Half-Cell Potentiometer apparatus. This apparatus measures the potential differences and provides insights into the corrosion resistance of the concrete. A comparative analysis is conducted between concrete made from Portland Pozzolanic Cement (PPC) and Ordinary Portland Cement (OPC) of Grade 43(both). Based on our findings, it is evident that the PPC-made concrete exhibits higher durability and superior resistance against corrosion compared to concrete made with OPC. This research underscores the importance of durability and highlights the significant role of various factors such as hydrochloric acid, sulfuric acid, sodium chloride, and corrosion.
