TEN YEAR REPORT ON THE LONG-TIME STUDY OF CEMENT PERFORMANCE IN CONCRETE

NO CONSISTENT RELATION WAS FOUND BETWEEN THE COMPOSITION AND FINENESS OF THE CEMENTS AND THE BEHAVIOR OF CONCRETE EXPOSED TO FREEZING AND THAWING. DIFFERENCES IN MANUFACTURE DID NOT SIGNIFICANTLY AFFECT THE DURABILITY OF THE CONCRETE. RESISTANCE TO SULFATE ATTACK WAS INCREASED BY REDUCTION OF THE POTENTIAL TRICALCIUM ALUMINATE CONTENT OF THE CEMENT. SUBSTANTIATING OTHER STUDIES, THE EVIDENCE WAS STRONG THAT AIR ENTRAINMENT GREATLY INCREASES THE ABILITY OF CONCRETE TO ENDURE FREEZING AND THAWING WITHOUT DETERIORATION AND WAS PARTICULARLY EFFECTIVE IN PREVENTING SCALING WHEN CHLORIDES ARE USED FOR ICE CONTROL ON CONCRETE PAVEMENTS. /PCA/
