Figure 4. Flexural strength comparisons between Control group (C) and experimental groups (S1, S2, S3). The calculated mean flexural strength values with standard deviation error bars are expressed.

Figure 5. Compressive strength comparisons between Control group (C) and experimental groups (S1, S2, S3). The calculated mean compressive strength values with standard deviation error bars are expressed.

Figure 6. Graphical presentation of mean percent mass change (%) of group C and experimental groups (S1. S2, S3), after 1 day., 3 days, 7 days, and 10 days. The calculated mean % mass change values along with standard deviation error bars are expressed for group C and experimental groups (S1, S2, S3).
