Mean, standard deviation, minimum, and maximum of the modulus of elasticity (MOE) and flexural strength (MOR) of all test samples, moisture content (m.c.) = 8.42%, n = 6 (a and b values with the same letter are not significantly different: ANOVA, Post-Hoc Tukey HSD, α = 0.05), values are significantly different to the control (epoxy) (ANOVA; p < 0.05).
