UTILISATION OF SUGERCANE BAGASSE ASH AND COAL FIRED BOILER ASH IN CONCRETE

Energy is the foremost backbone of modern society of the world and the electric power from thermal power stations is a major source of energy, in the form of electricity. India stands sixth in energy demand and depends on thermal power plants for its major energy needs. About 70% of energy consumption is from the thermal power plants, which in turn produces coal combustion products (CCP) as by-products, as they burn coal for energy production. Coal ash consist of fly ash and bottom ash. Bottom ash establishes 20% of total coal fed in the boiler. There have been numerous investigations on the use of fly ash as construction materials but when it comes to bottom ash, it is very few.It is now a global concern, to find a social, economical and environmental friendly solution to sustain a cleaner and greener environment. Today Study has been conducted to recycle valuable material and reduce the volume of hazardous solid waste and other pollutants, which is harmful for living organisms. The use of Coal Fired Bottom ash and Sugarcane Bagasse Ash can improve various properties in fresh and hardened state of concrete and also decreases the cost of construction.
