Effect of Mechanical Properties On Light Weight Sustainable Concrete With The Use of Waste Coconut Shell As Replacement For Coarse Aggregate

Abstract

Abstract Concrete is one of the most important material that is used in the construction industry all around the world. A larger part of the capacity in concrete is generally employed by the coarse aggregate. Due to the tremendous use of coarse aggregate in the construction industry the material is getting degraded. In order to preserve the natural material, we are in search of an alternate material that can be used in concrete instead of the original one. So in this research work a try has been attempted to study the mechanical behaviour of light weight concrete when we use coarse aggregate as waste coconut shell inside concrete. To improve the strength of concrete we also use the sisal fibers in various proportions ranging between 1% to 5% in accordance to the binder weight. After the mechanical properties tests such as the compression test, spilt tensile strength, flexural test, modulus of elasticity test, impact resistant test were conducted finally it was concluded that there was increment in the compression strength up to 5%, tensile strength was increased to 17% elastic modulus to 7% when the fiber content used was 3%. Thus with the use of these waste materials it was found that the concrete's strength gets increased and it leads to the formation of sustainable concrete thus reducing the pollution in the environment.
