Experimental Study on Walnut Shell Aggregate on FRC

Abstract

Consumption of Concrete is very high in the construction industry because of its high durability and structural strength. This leads to decrease in natural aggregates and imposed many environmental issues. The urbanization resulted in huge production of waste materials causing pollution to the environment. By using waste material like flyash, sugarcane bagasse ash, human hair, rice husk and walnut shells, pet fibres, etc., in concrete will reduce a cost and environmental impact which leads sustainability. Fibre reinforced concrete (FRC) is the one of the methodologies used by many of the concrete industries to enhance the strength of concrete. Even there are many types of natural and artificial fibres are available in market, the polypropylene fibers are generally used. In this study the strength characteristics of FRC is improved by adding Walnut shell aggregate. The FRC with 1.5% of polypropylene fibre to the volume of concrete is prepared and partial replacement of Walnut Shell Aggregate in 15, 20, 25 and 30% is done to study its effect on strength characteristics. Based on the results, the optimum percentage of WSA is obtained.
