Acid Attack | Concrete Experts International
What is Acid Attack? Concrete is susceptible to acid attack because of its alkaline nature. The components of the cement paste break down during contact with acids. Most pronounced is the dissolution of calcium hydroxide which occurs according to the following reaction: 2 HX + Ca (OH)2 -> CaX2 + 2 H2O . (X is the negative ion of the acid)
