Abstract

As we know that the construction Industry is the most important industry for any country. It plays significant role in national economy. To develop the any country the major infrastructures required are  schools, hospitals, offices, power system and other buildings, water supply, sewerage, drainage, railways, roads, airports, ports, irrigation system, etc. The consumption of Concrete is approximately thirty Billion tons per year that leads to high consumption of cement. As the concrete is the mixture of cement, aggregate (fine aggregate and coarse aggregate) and water & cement is the main ingredient of conventional concrete. The generation of cement causes major amount of air pollutants, which adversely affects the environment and is responsible for a major amount of greenhouse gases such as carbon-dioxide emission in the atmosphere. So, to reduce the emission of greenhouse gases in production of concrete, various types of modern sustainable concrete  using  industrial waste like rice husk ash,  slag, silica fume, blast furnace slag  fly ash. By Re-using these waste materials the harm to the environment can be decreased. In the present study partial replacement of Ordinary Portland Cement with Sugarcane Bagasse Ash in concrete will be done. The primary objective of this study is to determine properties of

concrete in fresh (green) stage and in hardened stage.  The concrete cubes (samples) of concrete (Cubes) were made for M30 (using IS codes 10262:2009 and 2016) with different mix Percentages of Sugarcane Bagasse Ash (i.e. 5%, 10%, and 15%) with this a normal mix of M30 concrete was also made. The innovation in the present study is to find replacement dose of Sugarcane Bagasse Ash for M30 grade of concrete by comparing the results of normal mixed concrete with SBA mixed concrete. By using of waste material will help the Society by providing pollution free environment and decreasing the problem of landfills for waste materials. Comparative results are satisfactory in case of fresh properties of concrete. However the Compressive Strength Test for M30 grade concrete the value of SBA percentage that can be added without adversely affecting the strength of concrete is only up to 5%.
