Modification of concrete is very essential for eco-friendly environment for present scenario. Show we are using agricultural waste in concrete to modify the concrete and to reduce problems of waste disposal and land utilization for waste. The agricultural wastes which are used in this project: - i). Coconut shell ii). Rise husk ash Coconut shells are by-products of coconut oil production. Coconut shells are used in the production of activated carbon due to hardness and high carbon content. Concrete using Coconut Shell aggregates resulted in acceptable strength required for structural concrete. Coconut Shell may offer itself as a coarse aggregate as well as a potential construction material in the field of construction industries and this would solve the environmental problem of reducing the generation of solid wastes simultaneously. . The impact resistance of Coconut Shell concrete is high when compared with conventional concrete. Moisture retaining and water absorbing capacity of Coconut Shell are more compared to conventional aggregate. Cost reduction of 40% can be achieved if coconut shells are used to replace gravel in concrete. The amount of cement content may be more when Coconut Shell are used as an aggregate in the production of concrete compared to conventional aggregate concrete. Thus cement can also be replaced by rice husk ash which is an agricultural waste to make it low cost material. Rice husk ash (RHA) is a by-product from the burning of rice husk. This husk contains about 75 % organic volatile matter and the balance 25 % of the weight of this husk is converted into ash during the firing process, is known as rice husk ash (RHA). This RHA in turn contains around 85 % - 90 % amorphous silica. Thus Rise husk is replaced partially by cement and Coconut shell is replaced by aggregate in various proportions. Then the concrete specimen is compared by testing on 7th, 14th and 28th day with water cement ratio of 0.5. Compressive strength tensile strength, workability, etc. will be shown in result. According to result of RHA moulds and coconut shell moulds the ratios are formed for using RHA and coconut shell together in concrete.

INTRODUCTION Concrete is the world’s most used construction material. The consumption of concrete has been increasing at a higher rate due to the demand placed by the development of infrastructure in both developing and developed countries. The negative consequences of increasing demand for concrete include depletion of aggregate deposits; environmental degradation and ecological imbalance. The possibility of a complete depletion of aggregate resources has rendered continued use of aggregates for construction unsustainable. In view of this challenge, researchers throughout the world have been investigating ways of replacing aggregates to make construction sustainable and less expensive. Research addressing environmental and sustainability issues in construction has generated lot of interest in the world. While wastes generated by industrial and agricultural processes have created disposal and management problems which pose serious challenges to efforts towards environmental conservation, their use contributes to resource conservation, environmental protection and the reduction of construction costs, since waste materials can be obtained at little or no cost, while making significant contribution to the conservation of natural resources and maintenance of ecological balance. The potential of using agricultural wastes in civil engineering and building construction works have been investigated by various researchers. In today’s scenario everyone looks for economic construction with good strength and durability. Conventi onal concrete is good but not economical where less loading and light weight concrete is required. According to the requirement of construction such as light weight concrete, high strength concrete, low cost concrete etc, we need to modify the concrete by using
