Abstract

This project aims to investigate the effect of bentonite and spent bleaching earth (SBE) addition on the sintered mechanical properties of glass waste composite. The bottle glass waste was used as main raw and spent bleaching earth and borate are used as fillers. The bottles were crushed using a hammer to get pieces of glass with a size of 2-3 mm. The glass pieces were grounded using the planetary ball grinding machine. Powder glass that formed was sieved using 75 μm siever. The glass powder was mixed with SBE and bentonite at compositions of 65:30:5, 65:25:10, 65:20:15 and 65:15:20 weight percentage. The mixed powder was compacted using a manual uniaxial hand press. After that, the samples were sintered in the furnace for 15 minutes at 8500C with heating and cooling rate 2oC/min. The microstructure of the samples were scanned using scanning electron microscope (SEM), the phases were examined using X-ray diffraction (XRD), hardness of the samples were tested using Vickers hardness and density of the samples were analyzed using densimeter. From XRD results, 65:25:10 composition shows carneigeit only and gave highest hardness reading. However, hardness of 65:15:20 and 65:20:15 compositions show only slight differences with only 2.5Hv. On the other hand, 65:15:20 composition shows lowest porosity based on SEM pictures and highest density with 2.33 g/cm3. The results suggest that the 65:15:20 composition is more suitable to be used in industrial application especially in tiles production based on hardness test’s result.
