Geopolymeric Building Material By Using Synergistic Utilization Of Industrial Waste

Abstract

In present age the industrial waste are generated in huge amount. It mainly affects to environment, health etc. Due to rapid urbanization and industrialization the production of various types of solid wastes which pose serious problem to the environment have been generated. So the disposal and reuse of solid industrial wastes like phosphogypsum, flurogypsum, fly ash, slag and lime sludge, etc. become a big challenge to us .Recycling of such wastes and using them in construction materials is the solution not only to the pollution problem but also an economical option in construction [1]. It is estimated that about 300 million tones of inorganic waste from industrial and mining sectors are generated every year in India. We also see that while manufacturing cement, a huge quantity of CO2 is emitted by industries, it ultimately affect the environment and create a big problem of global warming [2]. Therefore it is necessary to take initiative to reduce the use of such cement [2]. And also the products that causes a major harm to the environment. Synergistic utilization of major industrial wastes generated in India, namely fly ash, blast furnace slag and red mud, has been explored to develop novel building components using geopolymerisation. These include: (a) high strength cements (b) self glazed wall tiles, and(c) pavement tiles. Fly ash was used as main source of silico-aluminate for geopolymerisation. Granulated blast furnace slag (GBFS) and red mud were used individually or in combination with fly ash to harden properties of the developed components. In view of utilization of industrial waste in construction material, the present paper reviews various waste materials at different levels in construction material [1]. The reviewed approach for development of new construction material using industrial waste is useful to provide a potential sustainable source.[1]
