A SURVEY ON UTILIZATION OF SUGARCANE BAGASSE ASH AND COAL-FIRED BOILER ASH

Portland cement is the most important ingredient of concrete and is a versatile and relatively high cost material. Large scale production of cement is causing environmental problems on one hand and depletion of natural resources on other hand. This threat to ecology has led to researchers to use industrial by products as supplementary cementations material in making concrete. A number of studies are going on in India as well as abroad to study the impact of use of these pozzolanic materials like Sugarcane Bagasse Ash and Coal fired boiler bottom Ash as a cement replacements and the results are encouraging. Addition of these materials to concrete has many advantages like high strength, durability and reduction in cement production. Due to increasing construction activities, there has been a huge environmental impact especially the risks related to depletion of river bed and its consequent effect on the aquatic life, natural water table and over all ecology of the system. Various replacements of sand is a hot research topic worldwide. Thermal power plant coal bottom ash is a waste material if used as construction material will contribute to sustainability. Advantages of using coal bottom ash are that, it will give us an eco-friendly concrete and cost of dumping these waste material also decreased, thus serving the need of the hour.
