Water absorption test and compressive strength test were conducted to determine the quality standards of paving blocks. This research was conducted by using a mixture of fly ash, bottom ash and cement. The tests carried out in this study were water absorption test and compressive strength test using 3 compositions of 5%, 8% and 12%. In each composition using 3 samples for testing. Tests were carried out with a vulnerable time between 7 days, 14 days and 28 days. The highest water absorption results in the 8% composition with water absorption of 1.467%. The highest compressive strength results in the 8% composition with a compressive strength of 10.479 Mpa.
