  • Corrosion inhibiting hydraulic cement additives and compositions containing same
    Patent number: 4946506
    Abstract: An additive combination for hydraulic cement compositions is provided which advantageously provides corrosion inhibition and set acceleration, in combination with a high level of fluidity and retention of fluidity over a desired period of time. The cement additive combination comprises an alkali or alkaline earth metal nitrite and a graft copolymer plasticizer comprising a polyether backbone and side chain polymers formed by polymerization of ethylenically unsaturated monomers.Fluid hydraulic cement compositions are further provided comprising these additive combinations.
