EARLY HIGH-STRENGTH CONCRETE FOR PRESTRESSING

THE TECHNIQUES ARE DISCUSSED WHICH ARE PRESENTLY AVAILABLE FOR PRODUCING EARLY HIGH-STRENGTH CONCRETES. THE EFFECTS OF MIX PROPORTIONS, WATER-CEMENT RATIO, AND METHOD OF COMPACTION ARE DISCUSSED. THE INFLUENCE OF CURING CONDITIONS, THE ADVANTAGE OF PONDING LOW WATER-CEMENT RATIO CONCRETE, AND THE USE OF HIGHER TEMPERATURES EITHER BY RETAINING THE HEAT OF HYDRATION IN THE CONCRETE PRODUCT OR BY CURING WITH SATURATED STEAM ARE DISCUSSED. THE INFLUENCE OF TYPE AND AMOUNT OF CEMENT, ACCELERATORS, COMPACTION, AND AGGREGATE CHARACTERISTICS ARE DESCRIBED. DATA ON OTHER PROPERTIES SUCH AS ELASTICITY, CREEP, DRYING SHRINKAGE, BOND TO STEEL, AND DURABILITY ARE PRESENTED. /PCA/
