Type IS Cement blends slag with Portland cement, cutting clinker content while improving long-term strength, sulfate resistance, and durability. A practical way to produce better concrete and lower its carbon intensity at once. Our Type IS Cement meets ASTM C150 and C595 specifications.
Slag reacts more slowly than Portland cement, and that slower reaction is an advantage in higher temperatures, in mass concrete, or in mix designs requiring higher cement contents. Concrete made with Type IS cement keeps gaining strength well past the ages at which ordinary concrete strength has levelled off, and its refined pore structure resists sulfates and chlorides. Lower heat of hydration also helps in mass pours, where controlling thermal cracking matters.
