Cement - CP III (cement production)

The activity generating the emissions is cement production, CP III. The reference product is cement, CP III. The product cement, CP III represents cement (CP III) according to ABNT NBR 16697, also known as Portland blast-furnace slag cement. CP III has between 35% to 70% of blast-furnace slag (weight-%). Granulated blast furnace slag is a by-product of iron production and, when finely ground, it is also a cementing material with hydraulic properties. Slag hydration alone is too slow to give structural properties to cement, but when the slag is combined with Portland cement, the hydration is accelerated due to the extra amount of calcium hydroxide and gypsum. The reference product amount is 1. The cut-off classification is allocatable product. The activity type is ordinary ordinary transforming activity.
