　　Calcium fluoride can be used as mineralizer in the manufacturing of Portland cement clinker in order to decrease the temperature of clinkerization and/or increase the alite content of clinker.Also, by-products with fluorides could be valorized as mineralizers, for example by-products of the primary aluminum industry.But it is necessary to evaluate and understand the influence of these additions on the composition of the cement phases.
