The crushed groundnut shell is partially replaced for fine aggregate as sand. As the eggshell also contains calcium and has same chemical composition they can be used as a partial alternative material for cement as anyhow they get disposed as poultry waste.As eggshell are utilized in different percentage combinations(0 -15%) to find out the possibility of using them as a material which can replace cement, Crushed groundnut shell is replaced partially with fixed percentage(3%) as an alternate to sand and in addition 1% of nylon fibre has been added along with these combinations. Crushed Groundnut Shell and eggshell contributes towards Waste management and also helps in reducing the cost of construction as it reduces the quantity of natural sand and cement to a certain limit. In this experimental research we study various strength parameters like Standard Compressive strength, Standard Flexural strength, Standard Split Tensile strength. KEYWORDS: Concrete, Nylon Fibre, Crushed Groundnut shell, Eggshell powder, Cement, Fine Aggregate. I. INTRODUCTION Concrete is a material which is a conglomerate of three elements, comprising of cement, aggregate (fine aggregate and coarse aggregate) and water along with admixtures and fibres. In the making of concrete, cement, sand (fine aggregate), coarse aggregate (gravel, rock) are fused together with water in a certain percentage to attain the desired strength. It has been seen over the past few years concrete technology have seen a rapid growth and its improvement in strength and other structural properties through the use of steel reinforcements. Due to increase in demand and consumption of more natural sand (fine aggregate) and cement, made us to inspect alternative substance(material) for “Cement” and “Sand”. So in our experimental study, cement will be partiall y replaced by eggshell powder and fine aggregate will be partially replaced with constant percentage of crushed groundnut shell along with the addition of nylon fibre which contributes towards waste management and also to lessen the cost of construction and environmental pollution .As building industry develops, increasingly specialized and more durable materials or products are in a great demand which is why fibre reinforcement took an important role in modern construction techniques. II. Objective: Our main objective is to:  To find out or investigate the pre-eminent mix proportion for the partial replacement of ESP for cement , constant percentage replacement of CGS for fine aggregate along with the addition of nylon fiber in concrete.
