3. Results and conclusions
Figure 1 presents the mechanical strength values of 4x4x16 cm measured mortars. The results show that the compressive and flexural strength values are significant important compared with a traditional OPC mortar. The flexural values present close to 10 MPa at 7 days and increasing to 12 MPa at 6 months. The compressive strength of the samples had close to 75MPa at 7 days and also increasing this value towards 85-90 MPa of strength, this is a very significative compressive strength compared with the OPC. The total porosity determined was 12%. The XRD mineralogical study shows the formation of hexagonal phases at this stage – CAH10 and C2AH8 phases.
