Abstract:
Over 300 million tones of industrial wastes are being produced per annum by chemical and agricultural process in India. These materials pose problems of disposal and health hazards. The wastes like phosphogypsum, fluorogypsum and red mud contain obnoxious impurities which adversely affect the strength and other properties of building materials based on them. Paper making generally produces a large amount of solid waste. Paper fibers can be recycled only a limited number of times before they become too short or weak to make high quality paper. This paper mill sludge consumes a large percentage of local landfill space for each and every year. Fiber reinforced concrete becomes an option whenever durability (limited crack widths) or safety considerations are design criteria. They improve the performance (strength and toughness) of brittle cement-based materials by bridging cracks, transmitting stress across a crack and counteracting the crack growth .The steel fiber is the most common fiber type in the building industry; plastic, glass and carbon fibers contribute to a smaller part to the market. To reduce disposal and pollution problems emanating from these industrial wastes, it is most essential to develop profitable building materials from them. Keeping this in view, in this study low cost Self Compacting Concrete with steel fiber reinforcement incorporating lime sludge waste as partial replacement to cement is being done. The replacement level of lime sludge with cement is from 5% to 25%. The variation of steel fiber is from 0.5% to 2 %.
