Fig.2. Boxplots of compressive strength for different humidity levels

Concerning to the humidity, there are no major differences in the compressive strength, although it should be noted that the highest values of resistance correspond to cases of 25% and 75% humidity.

Fig.3. Boxplots of compressive strength for the interaction between ashes percentage and humidity

Concerning to the interaction, Fig. 3, shows differences in terms of the variability of the data, most pronounced in the greater percentage of ashes. Furthermore, the greatest median values are achieved with greater percentage of ashes
