The abundance of tile waste is used as a material innovation in the manufacture of concrete and paving. However, the results of research done by new researchers mostly only as filler material. The paving block which was added as a cement powder substitution material decreased compressive strength along with the tile waste percentage addition (Ridwan, 2017). Thus, researchers try to optimize tile waste treatment before being used in the paving blocks with raise the fuel temperature up to 900°C to obtain more amorphous pozzoland. Waste tile contains SiO2, CaAl2Si2O8, Fe2O3 and Mg2 (SiO 4) on the testing of XRD so compliant as pozzoland material. This research used powder waste as a material of cement substitution with 0%, 5%, 7%, and 10% of cement weight with variation of fuel temperature 750 oC, 800 oC, 850 oC and 900oC. The results showed that by increasing the fuel temperature up to 900°C compressive strength increased by 5.9% and water absorption decreased by 14.5%. However, by increasing the percentage of tile waste, compressive strength decreased up to 7.2%. Testing is supported by the SEM results wich indicate that the greater percentage used then the paving surface is also more hollow.
