## 3 Results  
The specimens were subjected to load application until fracture failure. Table 2 showed mean (\(\pm\)SD) value of maximum load (N) application, flexural strength (MPa), and flexural modulus (GPa). Figures 4 and 5 represent inter-group distribution of flexural strength and flexural modulus respectively by using a Box-Whisker Plot. Specimens from Group 1 showed the least mean values for flexural strength (89.15 \(\pm\) 9.70 MPa) and flexural modulus (4.310 \(\pm\) 0.912 GPa). Whereas, highest mean values for flexural strength (168.04 \(\pm\) 45.95 MPa) and flexural modulus (5.861 \(\pm\) 0.501 GPa) were recorded by group 5 specimens. Table 3 shows the inter-group statistical comparison of mean flexural strength. The distribution of mean flexural strength is significantly lower in Group 1 compared to Groups 2 and 5 (\(P\)-value \(<\) 0.01 for both). The distribution of mean flexural strength on Group 2 is significantly higher when compared to Group 4 (\(P\)-value \(<\) 0.01). The distribution of mean flexural strength is significantly lower in Group 2 as compared to Group 5 (\(P\)-value \(<\) 0.05). The distribution of mean flexural strength is significantly higher in Group 5 as compared to Groups 3 and 4 (\(P\)-value \(<\) 0.001 for both). Table 4 shows the inter-group \begin{table}
