All excess water and laitance shall be removed removed from the surface of the concrete by scraping. Bleeding water shall not be mixed into the concrete.
-
The surface of the concrete shall be sloped, grooved and carefully finished to prevent future pounding use suitable tools/equipment.
f.
Slope of road surface shall refer to engineering drawing for road and pavement section.
Curing -
Curing shall commence immediately immediatel y after the concrete surface is finished. Concrete surface, including the vertical sides, shall be completely covered with curing material.
-
Burlap shall be kept continually moistened during the curing period. Polyethylene Polyet hylene sheeting or waterproof paper shall be overlapped to prevent moisture loss from concrete. A curing compound may be applied after approval by CLIENT.
-
Curing shall be continued for at least 5 days when the temperature temperatu re is 21°C or higher or for at least 7 days when the temperature is less than 21°C. If the concrete contains high early strength Portland cement, the curing period shall be reduced to at least 3 days.
-
The finished pavement shall be closed to pedestrian traffic for a minimum of 3 days and strictly prohibited to vehicular traffic until the concrete has attained its designed compressive strength.
