Compressive strength characteristics of mortar containing waste pottery fine powder were investigated in this study. The experimental variables selected were 5, 10, and 15 percent replacements of cement with waste pottery fine powder. The findings are summarized as follows: (1) compared with the strength of the control specimens with no replacement rate, compressive strength of the mortar at 7days decreased by 3% and 9.3%, respectively at 5% and 10% replacement rate of cement with waste pottery fine powder, but (2) compressive strength of the mortar at 28days increased by 5.9% and 6.9%.
