| dc.description.abstract | 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. | en_US |
