Effect on mechanical properties of lightweight sustainable concrete with the use of waste coconut shell as replacement for coarse aggregate

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 bers 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, exural test, modulus of elasticity test, impact resistant test were conducted nally 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 ber 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.

Sustainable Reinforcement: Exploring Hypo Sludge and Sisal Fiber Integration in M25 Grade Concrete for Eco-Friendly Solutions and Assessing Environmental Impact

“…The positive outcomes of this study encourage further exploration of sustainable alternatives, urging stakeholders in the construction industry to consider the ecological impact of their materials and practices. Then, collectively striving for a more sustainable future, the integration of hyposludge and novel sisal fiber into concrete stands as a promising and impactful endeavor, promoting a harmonious balance between construction advancements and environmental responsibility (Natarajan et al 2022;Silva et al 2020).…”

Influence of Chemical and Thermal Treatment Methods on the Mechanical and Micro-Structural Characteristics of Coconut Shell based Concrete

“…From the thorough literature review carried out in the past (Bari et al, 2021;Sukontasukkul et al, 2019;Prakash et al, 2021;Natarajan et al, 2022;Liu et al, 2023), it can be seen that no previous studies have worked on identifying the efficiency of different treatment methods for coconut shell aggregates to be used for the development of light weight aggregate concrete. Moreover, the previous study on the quality improvement of CSC shows lack of information regarding the influence of heat treatment on the properties and strength of CSC.…”
