Concrete is a very wide issue in the civil engineering area. Modification of concrete is very essential for eco-friendly environment for present scenario. So using agricultural waste in concrete to modify the concrete and to reduce problems of waste disposal and land use to waste. The agricultural wastes which are employed in this project are Coconut shell and 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 C content. Concrete using Coconut Shell aggregates resulted in acceptable strength required for structural concrete. Coconut Shell may offer it as a coarse aggregate as well as a potential building material in the area of construction industries and this would solve the environmental problem of thinning out the generation of solid wastes simultaneously. The Coconut Shell-cement composite is compatible and no pre-treatment is demanded. Coconut Shell concrete has better workability because of the smooth surface on single position of the scales. The impact resistance of Coconut Shell concrete is high when compared with conventional concrete. Moisture retaining and water taking up 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 measure of cement content may be more when Coconut Shell is applied as an conglomeration in the production of concrete compared to conventional aggregate concrete. Thus cement can also be substituted by rice husk ash, which is an agricultural waste to cause it a low cost material. Rice husk ash (RHA) is a byproduct from the combustion of rice straw. This husk contains about 75 % organic volatile matter and the balance 25 % of the weightiness of this husk is converted into ash during the dismissal 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 dimensions. Then the concrete specimen is compared with testing on 7th, 14th, and the 28th day with water cement ratio of 0.5. Compressive strength, tensile strength, workability, etc. Will be shown in the event. Granting to the results of RHA molds and coconut shell molds the ratios are formed from using RHA and coconut shell together in concrete. This concrete can be used in roads, embankments, garden flooring, etc.
