^aThe value of compression modulus, and compressive strength were expressed as mean ± SD of 3 samples (n = 3). The use of superscripts on each column represent the statistical significant differences between groups. The groups with the same superscripts within each column indicate that the values are considered not significantly different (p > 0.05).
