Cement CP III (cement production CP III)

Emissions generated by the activity within the product supply chain as described in ecoinvent v3.10. 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 cut-off classification is allocatable product. The activity type is ordinary transforming activity. The reference product amount is 1.
