During the manufacturing process the materials are heated in a blast furnace to a molten state. Hardened cement composites constituted of cement, ground granulated blast furnace slag powder and blast slag furnace sand as fine aggregate are excellent sulfuric acid resistance because of forming white colored protective film based on calcium sulfate. Slag cement will provide lighter concrete with higher reflectivity than plain portland cement concrete. Slag cement is a hydraulic cement formed when granulated blast furnace slag (GGBFS) is ground to suitable fineness and is used to replace a portion of portland cement. These three types of materials have been extensively considered in the last 10 years. Evaluation of calcium silicate slag cement as partial replacement of cement.
