AN INVESTIGATION OF THE DURABILITY OF STEAM CURED CONCRETE, FINAL REPORT

THE DURABILITY OF STEAM CURED CONCRETE UTILIZING SEVERAL DIFFERENT CEMENTS WAS STUDIED THROUGH THE EVALUATION OF RESULTS OF TESTS FOR FREEZING AND THAWING RESISTANCE, SULFATE RESISTANCE, AND VOLUME CHANGE. DATA COLLECTED FROM THE ABOVE TESTS APPEAR TO SUPPORT THE FOLLOWING CONCLUSIONS: (1) STEAM CURING PROCEDURES WHICH PRODUCE OPTIMUM 24-HOUR COMPRESSIVE STRENGTHS ALSO PRODUCE GOOD RESISTANCE TO FREEZING AND THAWING, SULFATE ATTACK, AND VOLUME CHANGES, (2) THE DURABILITY OF STEAM CURED CONCRETE IS INFLUENCED MUCH MORE BY CEMENT COMPOSITION THAN BY VARIATIONS IN STEAMING PROCEDURES, (3) IN COMPARISON WITH MOIST CURING, STEAM CURING AT TEMPERATURES OF 130 AND 160 F TENDS TO ENHANCE THE RESISTANCE OF CONCRETE TO SULFATE ATTACK AND VOLUME CHANGES, WHILE 190 F CURING TENDS TO LESSEN THE RESISTANCE, AND (4) STEAM CURING FOLLOWED BY ONE YEAR OF FIELD CURING PRODUCES COMPRESSIVE STRENGTHS APPROXIMATELY EQUAL TO THOSE OBTAINED FOR NON-STEAM CURED CONCRETES AFTER 28 DAYS OF STANDARD MOIST CURING. /AUTHOR/
