WATER RETENTION EFFICIENTY OF MEMBRANE CURING COMPOUNDS

THE WATER LOSS FROM THE SURFACE OF FRESH CONCRETE PROTECTED BY A MEMBRANE CURING COMPOUND IS INFLUENCED BY A NUMBER OF FACTORS ORGINATING IN THE ENVIRONMENT, THE CONCRETE, AND THE CURING COMPOUND ITSELF. A CHANGE IN WIND SPEED FROM 0 TO 4 MPH CAN MORE THAN DOUBLE THE WATER LOSS OVER A 72-HOUR PERIOD. OTHER FACTORS FOUND TO HAVE SIGNIFICANT EFFECTS INCLUDE AIR AND SURFACE TEMPERATURE, RELATIVE HUMIDITY, SURFACE TEXTURE, AND RATE OF COMPOUND APPLICATION. THE FORMULATION OF A TEST METHOD TO EVALUATE THE RELATIVE EFFECTIVENESS OF CURING COMPOUNDS MUST EXERCISE CLOSE CONTROL OVER THESE VARIABLES. /AUTHOR/
