Limestone calcined clay cements LC3 raw material

Limestone calcined clay cements LC3 are blended cements that combine clinker limestone calcined clay and gypsum The availability of the materials required to produce LC3 and the good performance that it achieves makes LC3 suitable as a sustainable replacement of Portland cement Significant advances have been made to assess the properties of LC3 compare it to other common blended
