O Concrete should be dried as quickly as possible, if necessary, using industrial fans. O Concrete should be allowed to dry as quickly as possible in ambient (existing) conditions. O Concrete should always be kept from drying until hydration has fully taken place. Concrete should be prevented from ever drying out by applying a constant source of water. O Concrete is already completely dry at the time it is poured.arrow_forwardcivil engg materialarrow_forward
