PROTECTION OF FRESH CONCRETE /IN FRENCH/

A COMPARISON IS MADE BETWEEN METHODS USED IN BELGIUM AND ABROAD FOR PROTECTING FRESH CONCRETE. PROTECTION AGAINST DRYING, INCREASE IN CONCRETE TEMPERATURE CAUSED BY SOLAR RADIATION, WASHING OUT BY RAIN AND COOLING DUE TO FROST AND NIGHT RADIATION IS PARTICULARLY IMPORTANT DURING THE FIRST THREE DAYS AFTER CONCRETING. LACK OF PROTECTION CAN CAUSE LOSS OF STRENGTH, SURFACE WEATHERING RESULTING IN THE ELIMINATION OF SURFACE GROOVING, CRACKING AT THE SURFACE OR THROUGHOUT THE THICKNESS OF THE SLAB. THE MOST REASONABLE OF THE COMMONLY USED METHODS OF PROTECTION CONSISTS IN PULVERIZING A WHITE-PIGMENTED CURING COMPOUND; THIS TECHNIQUE HOWEVER REQUIRES FURTHER RESEARCH. UNDER SOME ATMOSPHERIC CONDITIONS (RAIN, INTENSE RADIATION, DRY WIND AND FROST) REINFORCED PROTECTION IS NEEDED AND CAN TAKE THE FORM OF A MOBILE, LIGHTWEIGHT, INSULATING LOW-COST COVERING. /LCPC/FESR/CRIC/RRL/
