Cover Story: The study focuses to the production of cement mortars using upgraded recycled concrete sand (Figure 1a) for total natural sand replacement and thermally activated recycled concrete fines as a partial cement substitution material. The combined usage of upgraded recycled concrete sand for total primary crushed sand (Figure 1b) replacement and recycled concrete fines as partial cement replacement material is a promising option to produce cement mortars.
