Abstract

ADMIXTURE COMPOSITIONS FOR HYDRAULIC CEMENT COMPOSITIONS ARE DISCLOSED WHICH COMPRISE A BORATE ESTER OF A POLYHYDROXY COMPOUND AND A HYDRAULIC CEMENT WATER-REDUCING AGENT. THE NEW ADMIXTURES PROVIDE INCREASED SLUMP RETENTION IN HYDRAULIC CEMENT COMPOSITIONS WHILE CAUSING ONLY A RELATIVELY MINIMAL INCREASE IN THE INITIAL AND FINAL SETTING TIMES OF THE CEMENT MIX. ALSO DISCLOSED ARE ADMIXTURE COMPOSITIONS FOR HYDRAULIC CEMENT COMPOSITIONS WHICH COMPRISE A BORATE ESTER OF A POLYHYDROXY COMPOUND AND A HYDRAULIC CEMENT WATER-REDUCING AGENT. THESE ARE PREFERRED ADMIXTURES WHICH PROVIDE INCREASED SLUMP RETENTION IN HYDRAULIC CEMENT COMPOSITIONS WHILE CAUSING ONLY A RELATIVELY MINIMAL INCREASE IN THE INITIAL AND FINAL SETTING TIMES OF THE CEMENT MIX.
