Investigation on Fly Ash-Lime-Gypsum Mix Mixed with Stone Dust

Stone Quarry dust is a kind of solid waste material that is generated from stone crushing site which is abundantly available. It is estimated that there are over 12000 stone crusher units in India (Central Pollution Control Board Parivesh Bhawan East Arjun Nagar, Shahdara Delhi). Disposal of such wastes poses lots of environmental problems such as air pollution, health and environmental hazards. The best way to eliminate these problems is to make use of such waste. The research aims to utilize the bye-products of stone quarries i. e. stone dust and thermal power plants i. e. fly-ash by investigating their basic properties when combined together which can help to enhance the strength of composite materials. Keeping this in view an experimental study was conducted on locally available stone dust by mixing it with fly ash-lime-gypsum mix. The compressive strength of composite of fly ash-lime-gypsum-stone dust was found to increase after Burlap method of curing
