Cement - general use limestone (GUL) (cement production - average)

The activity generating the emissions is cement production, general use limestone (GUL), average. The Reference Product is cement, general use limestone (GUL). The product cement, general use limestone (GUL) represents General Use Limestone (GUL) cement according to CSA A3001. It is a finely ground inorganic powder that acts as a binding agent when mixed with water. This hydration reaction causes the cement to harden and set, making it essential for bonding materials like stones, bricks, and aggregates in the construction industry. GUL cement is produced primarily from calcareous rocks such as limestone, which undergo pyroprocessing at high temperatures to form clinker. The clinker is then finely ground with gypsum and a small amount of limestone to produce GUL cement. Unlike General Use (GU) cement, GUL cement can contain up to 15% limestone. This cement is regulated under CSA A3001 in Canada and is designed for a wide range of applications, including concrete, mortars, plasters, and grouts. With about 5% gypsum/anhydrite and up to 15% limestone, GUL cement also meets the ASTM C595 standard for Type IL cement in the United States and the EN 197-1 standard for CEM II cements in Europe." The Reference Product amount is 1. The cut-off classification is allocatable product. The activity type is ordinary transforming activity.
