Effect of acidic environments on cement concrete degradation

Joanna Julia Sokołowska , Piotr Paweł Woyciechowski


The paper presents assessment of the chemical resis tance of five concretes containing different binders, including common normal and high early strength cements CEM I ÷ CEM IV and mix of Portland cement and siliceous fly ash , treated with hydrochloric acid. Concrete compositions fulfilled conformity with sta ndard EN 206-1 for the most stringent chemical exposition class XA3. Due to the lack of the commonly used standard procedures for testing concrete exposed to environment of low pH, tests were performed following the own procedure assuming treatment of different durat ion and with different concentrations of HCl. Assessment of concrete ability to resist the chemical attack was based on its change of mass, compressive and tensile strength. Specimens exposed to acid aggression showed significant mass loss and mechanical properties decrease. It was statistically confirmed that aggressive environment parameters have a significan t effect on the chemical resistance of tested concretes.
