Cement - blast furnace slag 35-70% (cement production - blast furnace slag 35-70%)

Emissions generated by the activity within the product supply chain as described in ecoinvent v3.8. The product "cement, blast furnace slag 35-70%" represents Portland blast-furnace slag cement (CP III). It has between 35% to 70% of blast-furnace slag in mass composition. Granulated blast furnace slag is a byproduct 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.
