AIR-ENTRAINING ADMIXTURES

AIR ENTRAINMENT ENHANCES THE ABILITY OF CONCRETE TO RESIST THE POTENTIALLY DESTRUCTIVE EFFECT OF FREEZING AND THAWING AND CHEMICAL DE-ICERS. THE REPORT DISCUSSES: MATERIALS USED AS AIR ENTRAINING ADMIXTURES, FUNCTION OF ENTRAINED AIR, EFFECT OF MAXIMUM SIZE AGGREGATE ON REQUIRED AIR CONTENT OF THE CONCRETE, BUBBLE-SPACING FACTORS, FACTORS INFLUENCING AMOUNT AND CHARACTER OF ENTRAINED AIR, METHODS FOR DETERMINING AIR VOID CHARACTERISTICS IN BOTH FRESHLY MIXED AND HARDENED CONCRETE, AND CURRENT SPECIFICATIONS FOR AIR ENTRAINING ADMIXTURE. /PCA/
