IMPROVED AIR-ENTRAINING ADMIXTURES FOR CONCRETE

TEST DATA COVERING IMPROVED, SYNTHETICALLY DERIVED AIR- ENTRAINING ADMIXTURES FOR CONCRETE ARE PRESENTED. THE TEST DATA INDICATE THAT IMPROVED AIR-ENTRAINING ADMIXTURES CAN BE FORMULATED THAT OVERCOME THE LOSS IN COMPRESSIVE STRENGTH USUALLY ASSOCIATED WITH THE INCORPORATION OF AIR INTO HYDRAULIC CEMENT MIXES. DATA COMPARING THE MOST PROMISING OF THE MATERIALS TESTED WITH TWO ESTABLISHED COMMERCIAL PRODUCTS ARE PRESENTED AND SHOW THAT THE VALUABLE COMPRESSIVE STRENGTH PROPERTIES ARE RETAINED EVEN IN THE PRESENCE OF GROSSLY EXCESSIVE AMOUNTS OF ADMIXTURE. IT IS EXPECTED THAT PRODUCTS BASED ON THIS NEW MATERIAL WILL BE GENERALLY AVAILABLE TO THE CONCRETE INDUSTRY IN THE NEAR FUTURE. /AUTHOR/ /AUTHOR/
