Protection of concrete
1) Newly placed concrete shall be protected from rain, sun and wind by approved means viz: Hessian cloth, plastic sheets etc.
2) Concrete placed below the ground level shall be protected against contamination from falling earth, during placing.
3) The area in and around the actual place of the concreting shall be kept sufficiently dry, by constructing sufficiently watertight forms / cofferdam around the area to be concreted, to prevent loss of mortar through walls.
4) Continuously dewatering the area through out the period of concreting and till initial set of concrete occurs with the help of dewatering pumps shall not be resorted to.
