The activity generating the emissions is cement production, CEM IV/B. The Reference Product is cement, CEM IV/B. The product cement, CEM IV/B represents cement (CEM IV/B) according to EN 197-1, also known as pozzolanic cement. CEM IV/B is a blended cement that is made by partially replacing 36-55% of Portland cement with fly ash, which is a waste from power stations, and pozzolana (weight-%). Natural pozzolanas include volcanic ashes, opaline shales, and cherts that contain reactive compounds of silicon and/or aluminium. Fly ash is a synthetic pozzolana. The Reference Product amount is 1. The cut-off classification is allocatable product. The activity type is ordinary transforming activity.
