Abstract

Admixture compositions for hydraulic cement compositions are disclosed which comprise a borate ester of a polyhydroxy compound and a hydraulic cement binder. 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.
