From previous research works it is found that cow-dung ash and sugarcane bagasse ash are rich source of silica and they possess pozzolanic activity in cement concrete when used in certain proportion. Cow-dung is a byproduct of dairy farming industry it is commonly used as manure in agricultural fields. Sugarcane bagasse ash is a waste product of sugar industry and it is thrown as waste or used as fuel, the resulting ash will be dumped into landfills causing environmental pollution. Egg shell is a rich source of calcium as it is made up of 95% CaCo 3 compounds, so it contains around 50% of CaO which is a main ingredient of ordinary portland cement. This work involves the use of cow-dung ash, sugarcane bagasse ash and egg shell powder as partial replacement of cement in concrete production and also determination of properties of concrete like workability, compressive strength, split tensile strength, and flexural strength. Cow-dung ash and sugarcane bagasse ash mixture is varied up to 30% (0%, 5%, 10%, 15%, 20%, 25%,and 30%) and egg shell powder is added to the optimum cow-dung ash and sugarcane bagasse ash content cement concrete from 0 to 12.5% (0%, 2.5%, 5%, 7.5%, 10% and 12.5%). Key Words: Cow-dung Ash (CDA), Sugarcane Bagasse Ash (SCBA), Egg Shell Powder (ESP), Compressive Strength, Split Tensile Strength, Flexural Strength 1. INTRODUCTION Cement is a material which contains various constituents in it, mainly Calcium oxide and Silica. Many research scholars have discovered the Calcium and Silica containing materials and efforts are made to experimentally investigate the behavior of concrete with partial replacement of cement by those materials. Surprisingly, the strength characteristics of concrete were increased with the partial replacement of cement in concrete as compared to the conventional concrete. There are many advantages by the use of cement replacement materials in concrete, the major one is reduction in the usage of cement quantity required for the concrete production. Decreased cement requirement in the production results in the less release of main green house gas i.e. carbon-di-oxide into the atmosphere which is very hazardous to the environment, it increases the atmospheric temperature contributing to so called global warming. Use of alternative materials for cement may reduce the amount of CO 2 release to the environment due to decreased cement production, this is possible when the cement replacement materials in concrete are used in wide range. It is the emerging trend to use the cement replacement materials in combination with one another, this enables the use of waste materials in relatively larger quantities. In this work the category of waste materials used are Agricultural and Poultry waste namely Cow-dung Ash, Bagasse Ash and Egg Shell Powder. Among these wastes except cow-dung ash, other two wastes causes nuisance in the environment when they are not properly disposed off, and pollutes the landfill sites. 1.1 Cow dung ash Cow-dung is cattle excreta which can be used as manure for agricultural fields, recent research works have found that ash obtained from cow-dung is rich source of Silicon dioxide. Experimental investigation on cow-dung ash mixed cement mortar and concrete has been carried out to determine the behavior of fresh and hardened concrete. The result shows that cow-dung ash can be effectively used as a partial replacement of cement.

Sugar producing industries generates million tons of waste as bagasse. After processing the sugarcane to extract sugarcane juice it generates around 26% bagasse by weight of sugarcane. Bagasse thus generated is often used as fuel for sugar mills, and other small scale industries to produce heat energy for their
