Dry mortars consisting of Portland BL I 52.5 R cement (14%), dolomite and CaCO3 sands (85,8%) and organic additives (0.2%) were studied. Three types of dolomite sands with mean grain size >1.0 mm, 0.0–1.0 mm and 0.0–0.5 mm range were used. The mortars were prepared from variable amounts of each raw material (dolomite and CaCO3 sands) and in variable W/C ratios. The particle size distribution curves for the overall mixed raw materials were used for anticipating the microstructure and mechanical properties of cement based mortars.
► We prepare cement based mortars with variable amounts of dolomite and CaCO3 sands.
► The PSD curves for the overall mixed raw materials were obtained.
► The PSD curves served for anticipating the microstructure and mechanical properties.
► Manufacturers can use PSD curves as key tool in the preparation of specific mortars.
