    摘要: Hydraulic cement set-accelerating admixture compositions; cement compositions containing such admixtures; and methods for preparing said cement compositions. The admixture compositions comprise one or more nitroalcohols present in an amount effective to increase the set acceleration of a hydraulic cement composition. The invention further relates to a method of making a hydraulic cement composition comprising adding to a cement composition comprising a hydraulic cement binder, a nitroalcohol component in an amount effective to increase the set-acceleration of the binder, and to a cement composition comprising a hydraulic cement binder and a nitroalcohol set-accelerating agent.
