The impact of the OPC on the environment is important as its production generates a large amount of CO2. In order to reduce the use of pure raw materials as resources, the use of industrial waste or secondary materials in construction sites for the production of cement and concrete has been encouraged. The volume of wastes generated worldwide has increased over the years due to the population, social and economic performance and social development. One of the most attractive options for waste management is to minimize waste and reuse the possibility of recycling. The cost of cement used in concrete works is increasing and unsatisfactory, but the demand for this material and other housing needs is rising, so it is important to find alternatives that can be used alone or in a partial replacement.Today, green building is an essential part of ensuring sustainability, and concrete composites with siliceous fly ash (FA), coconut shell ash and ground nut ash. It results in sustainable and green concrete. In order to minimize the environmental threats caused by FA, coconut shell and ground nut waste disposal has been reduced cement consumption, it is necessary to effectively promote green concrete containing ash. In this paper, Fly ash, coconut ash, ground nut ash is generated by burning and grinding coal, coconut shell and groundnut shell respectively. The ash is mixed with cement in different proportion and the sample of cube and beam is prepared. The samples are then cured in water for 7 days and 28 days respectively. The tests such as compressive strength is measured on the cube, whereas, the flexural strength is measured on beam. Other tests such as Rebound Hammer, water absorption test and Ultrasonic Pulse Velocity Test are conducted. From the experiment, it has been analyzed that the percentage increase in the compressive strength after adding the ashes compared to the normal concrete of 8.19 % is obtained.
