Research on the Comprehensive Utilization of CPFL in Concrete Moisture Curing

Abstract:

Controlled Permeable Formwork Lining (CPFL) has particular water-storaging capacity, the mixing water remained in the CPFL can provide moisture curing for the surface layer concrete for a period time. In this paper, the water storage was tested, the appearance quality, rebound hardness and durability of the surface concrete were studied. Results shown that CPFL can significantly improved the appearance quality, early age rebound hardness, carbonation resistance, chloride ion penetration resistance and freezing-thawing resistance of the surface concrete; the coating age of anti-corrosion coating was shortened to 18 days, the cofferdam turnover rate was speeded up, the engineering cost was reduced; the coating adhesion was significantly improved and the thickness of dry coating film and adhesion of discrete were reduced. The benefit of using CPFL technology is remarkable, and it is worth promoting.
