| Abstract |
| Eighteen batch compositions containing varying proportions of blast furnace slag,
bagasse ash and glass cullet were fired in oilfiredfurnace at 1425±25°C for 2 hours,
in order to investigate the possibility of using these waste materials for melting
glasses. Of the eight compositions which gave glasses upon firing, two compositions
containing 50: 50 blast furnace slag and bagasse ash together with 5% Ti02 and 5%
B20 3 respectively, were having superior properties. All the glasses showed better chemical
resistivity than normal container glass, particularly those containing minor addition of
Ti02• The thermal expansion of the latter was qlso comparatively lower. Glasses for
making containers, fibres,Joams etc can be made out of the above waste raw materials
economically. |
