Description
Summary:Due to the growing extent of the sources of aggressive media, the concrete structures may be exposed to the action of organic species. The paper presents the results of the long-term study on the action of various organic substances on the cement-based material. The results obtained show the different aggressivity of the solutions of phenols, carboxylic acids and sulphonic compounds. Petroleum and mineral oil have been shown as unaggressive media. Observed increased expansions followed by crack propagation at the action of some media were adjudged to the cooperation of the mechanism of acidic attack and dispersive effect of surface activity of organic substances.
