Resumen:
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 >1.0mm, 0.0¿1.0mm and 0.0-0.5mm 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.
