EFFECTS OF ABSORBED MOISTURE IN AGGREGATES ON CONCRETE DURABILITY

216 CONCRETE SPECIMENS WERE MANUFACTURED FROM THREE AGGREGATE TYPES - LIMESTONE, GRAVEL, AND SLAG - THAT HAD 3 SIGNIFICANTLY DIFFERENT PORE SIZES AT 95% PROBABILITY LEVEL. THE AGGREGATES WERE SUBJECTED TO TWO DIFFERENT LEVELS OF SATURATION, SATURATED AND OVEN DRIED. THE CONCRETE SPECIMENS WERE CURED USING TWO DIFFERENT CURING PROCEDURES CONSISTING OF 1 DAY IN THE MOLD, 27 DAYS OF WET CURING AND 1 DAY IN THE MOLD, 13 DAYS OF WET CURING, 7 DAYS OF DRY CURING, AND 7 DAYS OF WET CURING. MOISUTRE MIGRATION STUDIES WERE MADE USING NUCLEAR TRACK EMULSION. THE STUDY REVEALED THAT PORE SIZE, CURING CONDITIONS, AND SATURATION CONDITIONS DID SIGNIFICANTLY EFFECT THE DURABILITY OF CONCRETE FOR SOME AGGREGATE TYPES ONLY. MOISTURE MIGRATED OUT OF THE SATURATED SLAG SPECIMENS DURING THE FREEZING AND THAWING PROCESS.
