QUALITY CONTROL IN CONCRETE ROAD CONSTRUCTION /IN FRENCH/

THE CONDITIONS NECESSARY TO ENSURE THE PRODUCTION OF HIGH-QUALITY CONCRETE ARE: PRELIMINARY CONTROL OF INGREDIENTS AND CONTINUOUS CONTROL DURING MANUFACTURE BY RECORDING PRODUCTION PARAMETERS. RECENT TESTS ON CONSTRUCTION SITES SHOW THAT IT IS POSSIBLE TO RECORD THE TEMPERATURE OF CEMENT AND WATER, TO RECORD THE WEIGHT OF AGGREGATES, CEMENT AND WATER IN A BATCH, AND TO EVALUATE THE CONSISTENCY OF CONCRETE AND REGUALRITY OF PRODUCTION BY RECORDING THE ENERGY CONSUPTION OF THE MIXER. RESULTS SHOW THAT IF CARE IS TAKEN IN OPERATING AND MAINTAINING THE EQUIPMENT, IT IS POSSIBLE TO OBTAIN A HIGH DEGREE OF REGUALRITY IN PRODUCTION. TESTS CARRIED OUT ON SAMPLES SHOW A WIDE DISPERSION IN MEASUREMENTS ON FRESH CONCRETE. THIS DISPERSION DECREASES FOR RESULTS OF MECHANICAL TESTS ON HARDENED CONCRETE. /LCPC(A)/RRL/
