Curing plays an important role on strength development and durability of concrete. Curing takes placeimmediately after concrete placing and finishing, and involves maintenance of desired moisture andtemperature conditions, both at depth and near the surface, for extended periods of time. Properlycured concrete has an adequate amount of moisture for continued hydration and development of strength, volume stability, resistance to freezing and thawing, and abrasion and scaling resistance.
Membrane-forming curing compounds are used to retard or reduce evaporation of moisture fromconcrete. They can be clear or translucent and white pigmented. White-pigmented compounds arerecommended for hot and sunny weather conditions to reflect solar radiation. Curing compoundsshould be applied immediately after final finishing.
