EPD: Portland-limestone cement, GUL-Type IL (Lafarge, Bath plant)

This EPD reports environmental transparency information for General Use (GU, Type I/II), General Use Limestone (GUL, Type IL) and High Early (HE, Type III) cements produced by Lafarge at its Bath, ON plant. Cements are hydraulic binders and are manufactured by grinding cement clinker and other main or minor constituents into a finely ground, usually grey colored mineral powder. When mixed with water, cement acts as a glue to bind together the sand, gravel, or crushed stone to form concrete, one of the most durable, resilient, and widely used construction materials in the world. The Table below sets out each cement type constituents and applicable standards. All Bath cements are sold in bulk.
