    CaOH can cause deleterious effects in concrete such as increased porosity and efflorescence -the formation of calcium carbonate crystals on the concrete or mortar surface-. Because fly ash reacts with the calcium hydroxide to form more calcium silicate hydrate -the binder derivative of cement- fly ash actually adds strength to the concrete and helps to remove an agent that may be harmful.
