Efflorescence is white powdery material formed on concrete surface when soluble salts migrate to the surface of concrete. It is produced due to low temperatures, moist conditions, condensation, rain, dew, and water added to the surface of fresh concrete to assist troweling. Certain forms of efflorescence are considerably difficult to remove and chemical agents may […]
