ABSTRACT:
An improved cement for making concrete and mortar comprises a blend of ground calcium carbonate or Portland cement kiln dust, or both, and ground, granulated blast furnace slag. While its physical and chemical characteristics differ from Portland cement, it is a functional substitute for Portland cement and may be used in combination with Portland cement in a wide range of proportions. The hardening and other characteristics of this slag-dust cement can be improved by the addition of SO.sub.3, ordinarily by adding ground gypsum and by the use of accelerators and high-range water reducing formaldehyde compounds.
