ABSTRACT:
Admixture compositions for hydraulic cement compositions are disclosed which comprise a borate ester of a polyhydroxy compound. The admixtures are effective water-reducing agents at relatively low dosages in hydraulic cements. They generally provide water reduction levels equal to or greater than those provided by the corresponding non-esterified polyhydroxy compound with a lesser degree of set retardation.
