EXPANSIVE CEMENT CONCRETE - PRESENT STATE OF KNOWLEDGE

THIS STATE-OF-THE ART REPORT OUTLINES THE HISTORIC BACKGROUND OF THE DEVELOPMENT OF EXPANSIVE CEMENT CONCRETES ABROAD AND IN THIS COUNTRY, PRESENTS THE RELEVANT NOMENCLATURE, AND SUMMARIZES THE CURRENT STATUS OF EXPANSIVE CEMENTS IN THE UNITED STATES. THE HYDRATION CHEMISTRY OF EXPANSIVE CEMENTS IS DESCRIBED AND VARIOUS FACTORS ARE DISCUSSED WHICH INFLUENCE THE RATE AND AMOUNT OF EXPANSION OF ALL THREE TYPES OF EXPANSIVE CEMENT CONCRETES. FIELD PERFORMANCE OF SHRINKAGE-COMPENSATING CONCRETE IS SUMMARIZED. THE INFLUENCES OF RESTRAINT, AGGREGATES, ADDITIVES, AMBIENT TEMPERATURES, FORMS, CONSISTENCY, FINISHING, AND CURING ARE DISCUSSED. FIVE HIGHWAY INSTALLATIONS ARE DESCRIBED, INCLUDING VARIOUS SPACINGS OF CONTRACTION JOINTS, CONTINUOUSLY REINFORCED PAVEMENT AS WELL AS AN UNREINFORCED ONE, AN APPLICATION OF SELF-STRESSING CONCRETE, AND THE USE OF TWO BRIDGE DECKS. /AUTHOR/
