Abstract:
Presents information about various chemical admixtures, based on an extensive literature survey and on results from an on-going laboratory test program, that can be used to decrease the freezing point of water while permitting cement to hydrate. At 20, -5, and -10 C, concrete made using an aqueous solution of sodium nitrite/calcium nitrite and concrete made using a solution of sodium nitrite/potassium carbonate performed well in strength tests.
