Development and Characterization of Charcoal filled Glass-Composite Materials made from SLS Waste Glass

Glass-composite materials were prepared from the soda lime silicate (SLS) waste glass, ball clay and charcoal powder at various carbon content, of 1wt. % C, 5wt.% C and 10 wt.% C, fired to temperature of 850 degrees C as an alternative method for land site disposal method as well as effort for recycling waster glass. The effect of charcoal powder on the porosity, water absorption and hardness properties were studied. Phase analysis studies revealed the present of quartz (ICDD: 00001-0649, 2 theta = 25.6 degrees and 35.6 degrees), cristobalite (ICDD 00004-0379, 2 theta = 22.0 degrees and 38.4 degrees) and wollastonite (ICDD 00002-0689, 2 theta = 30.1 degrees and 26.9 degrees). The results showed that the composite prepared from the mixture of 84 wt.% SLS, 1 wt.% of charcoal and 15 wt.% ball clay containing average pore size of 10 mu m has projected optimized physical and mechanical properties. It is observed this batch has projected lowest water absorption percentage of 0.76 %, lowest porosity percentage of 1.76 %, highest 4.6 GPa for Vickers Microhardness.
