TEMPERATURE AND CONCRETE

ABSTRACTS OF THE 13 PAPERS CONSTITUTING THE BOOK "TEMPERATURE AND CONCRETE" ARE GIVEN. THE PAPERS DEAL WITH THE FOLLOWING TOPICS: (1) A LITERATURE REVIEW OF SUSTAINED HIGH TEMPERATURES, EMPLOYING 61 SOURCES FROM 8 COUNTRIES; (2) THE EFFECT OF TEMPERATURES UP TO 1600 DEG F ON COMPRESSIVE STRENGTH OF STRESSED AND UNSTRESSED CONCRETE, TO PROVIDE ADDITIONAL INFORMATION ON THE EFFECT OF FIRES ON CONCRETE; (3) THE EFFECTS OF APPLIED TEMPERATURES OF 35--775 DEG F ON PCC, PLAIN CONCRETE, AND MORTAR, PARTICULARLY CHANGES IN COMPRESSIVE AND FLEXURAL STRENGTH, MODULUS OF ELASTICITY, MOISTURE CHANGE,SHRINKAGE, CREEP, CREEP RATE, AND CREEP RECOVERY UNDER VARIOUS TEMPERATURES AND MECHANICAL LOADS, ALL WITH REFERENCE TO THE DESIGN OF PRESTRESSED CONCRETE REACTOR VESSELS; (4) THE EFFECT ON THE ABOVE PROPERTIES OF A 70-113 DEG F RANGE, WITH REFERENCE TO THE DESIGN OF MASS CONCRETE DAMS; (2) LABORATORY AND FIELD STUDIES OF THE EFFECT OF TEMPERATURE DIFFERENTIALS ON SLABS, THE FIRST RELATING THE POTENTIAL TEMPERATURE EXPANSION OF WATER, CEMENT, AGGREGATE, REINFORCING STEEL, AND STEEL BEAMS TO STRESS IN CONTINUOUS SPAN BRIDGES IN THE 40-100 DEG F RANGE, AND THE SECOND CALCULATING THE STRESSES PRODUCED BY THE TEMPERATURES OBSERVED IN FIELD PAVEMENTS; (6) THE CURING PROCESS, WITH ATTENTION TO (A) VOLUME CHANGE AND STRENGTH MEASUREMENTS UNDER TEMPERATURES UP TO 200 DEG F AND DIFFERENT PRECURING TIMES, AND (B) CONCRETE CONSTRUCTION IN HOT CLIMATES, WITH REFERENCE TO CASTING AND CURING TEMPERATURE AND THE TYPE OF CEMENT; (7) LABORATORY MEASUREMENT OF THE EFFECT OF WATER-REDUCING ADMIXTURES ON THE TEMPERATURE RISE OF MASS CONCRETE; AND (8) A NOVEL PROCEDURE FOR APPLYING TEMPERATURE CHANGES TO MECHANICALLY LOADED STRUCTURAL MODELS OF CONCRETE STRUCTURES BY THE USE OF THERMOELECTRIC MODULES.
