Compressive strength
As expected, the compressive strength increased with curing
time [20,21] for all series (Table 6). Also as expected, higher compressive
strength values were obtained in CEM-I mortars than in
CEM II mortars (Fig. 8), due to the presence of limestone filler in
CEM-II. Again as expected, the compressive strength goes down
as the cement content decreases. Fig. 9 shows the relationship
between compressive strength and porosity, according to cement
content.
