HIGH EARLY STRENGTH ROAD CONCRETE

STRASSENBETON MIT HOHER FRUEHFESTIGKEIT

FOR REPAIRS AND OTHER CONSTRUCTION MEASURES WHERE A SHORT CLOSURE TIME IS NEEDED, IT IS NECESSARY TO HAVE A CONCRETE WITH HIGH STRENGTH AT AN EARLY STAGE. BY THIS IS MEANT A CONCRETE WHICH HAS DEVELOPED 70 TO 90 PERCENT OF ITS REQUIRED STRENGTH AFTER ABOUT 48 HOURS. THESE CONCRETES CAN NORMALLY ONLY BE PRODUCED USING ADMIXTURES. IN CERTAIN CASES IT IS RECOMMENDED TO MAKE THE NORMALLY STIFF CONSISTENCY OF THE FRESH CONCRETE FLUID FOR THE PERIOD OF INCORPORATION BY MEANS OF PLASTICIZERS. IT IS INTENDED TO OBTAIN INFORMATION ON THE POSSIBILITIES OF PRODUCING AN EARLY HIGH-STRENGTH ROAD CONCRETE HAVING SUFFICIENT VOIDS CONTENT, BOTH IN A NORMAL CONSISTENCY OR IN A SOFT OR POURABLE CONSISTENCY.
