Note. Similar lowercase letters in the same rows across groups indicate no significant differences (ANOVA, post hoc Tukey test at a significant threshold of ). Similar uppercase letters in columns show that aging within the groups has no significant effect on values from day one. CS, compressive strength; FS, flexural strength; SD, standard deviation.
