This EPD reports environmental transparency information for General Use (GU, Type I/II), High Sulphate (HS, Type V), General Use Limestone (GUL, Type IL), High Sulphate Limestone (HSL, Type IL – HS), High Early (HE, Type III), and Oil Well G (OWG) cements produced by Lafarge at its Exshaw, AB 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 Exshaw cements are sold in bulk
