Asbestos is a mineral fiber that has been used commonly in a variety of building construction materials for insulation and as a fire-retardant. Asbestos has been used for a wide range of manufactured goods, because of its fiber strength and heat resistant properties. Nevertheless harmful of asbestos is quite serious. Exposure to airborne friable asbestos may result in a potential health risk because persons breathing the air may breathe in asbestos fibers. To melt asbestos is required very high melting temperature more than 1,520℃ and specially asbestos cement slate need more energy for melting than that of pure asbestos because of cement contents. Therefore, to lower melting temperatures, or to control the basicity is inevitable to use the additives. In this paper, the waste glass was used to control basicity as additives. And we fulfilled about properties of asbestos cements slate, melting characteristics on the additives ratio and temperature, analysis of slag(SEM and XRD) etc. It is passible to lower melting temperature as a result suitable mixing the asbestos cement slate and waste glass. The result of basicity analysis, the optimal temperature is 1,400℃ and the ratio of additives is 67% condition. The results of this study will be suggested as a preliminary data for commercial plant.
