Supplementary cementitious materials (market for)

The activity generating the emissions is market for supplementary cementitious materials. The Reference Product is supplementary cementitious materials. Supplementary cementitious materials (SCMs) are materials used to substitute clinker in cement production. SCMs do not usually have an elastic demand as they are mostly produced as by-products. Examples of SCMs are: fly ash, by-product of coal-dired electricity, and blast furnace slag, by-product of iron and steel production. According to Scrivener et al. (2018) clay is the material that could supply an increased demand for SCMs. Scrivener et al. 2018. Calcined clay limestone cements (LC3).
