Abstract

Green Innovative Glass (GIG) is a ceramic tile that uses waste glass powder as a part of the composition of the clay mixtures. The basic raw material used for fabricating GIG is soda lime silica glass (SLSG) which were collected from PUM Cullet SDN BHD. located in Johor Bharu as the glass requested are from waste glass containers or bottles. There are two types of formulation of GIG ceramic tiles, which are green and white formulation. The objective of this paper is to conduct mechanical testing for GIG ceramic tiles and to gather information and data for fracture analysis, hence able to correlate the high performance of mechanical properties with the processing parameters, and composition of GIG ceramic tiles compared to the conventional ceramic tiles. This paper will conduct 3 steps of method which is sample identification, the preparation of the ceramic tiles before to the next step which is mechanical testing of GIG ceramic tiles on a three-point bending test, and finally fracture analysis on the surface of fracture. Flexural test results in the unglazed ceramic porcelain results in 33 kN/mm2 while the elongation is 5.74mm while the white GIG results in 36 kN/mm2 and the elongation is 3.6mm. Lastly the green GIG shows the highest stress absorption with 46 kN/mm2 and the elongation is 3.6mm. XRD analysis shows that unglazed ceramic porcelain contains cristobalite and para-wollastonite phase while the white and green GIG contain wollastonite, cristobalite, and fosterite. Fracture analysis shows that the alignment of the crack propagation from the unglazed ceramic porcelain shows that obvious cracks occurs in the material while not in the white GIG as it cracks more disperse and showing less crack with the presence of pores on the fracture surface. Lastly green GIG shows that the deepest cracks as it be able to repel lots of stress with less elongation.
