Abstract - Concrete is a superior building material created
ensuring that prosperity is accessible to future generations. In the sphere of construction, researchers have been working on innovative technologies that provide an environmentally beneficial technique [2]. In the modern age, the primary application of waste as a substitute is in the construction sector. Multiple wastes, such as crushed glass, brick waste products, sugarcane bagasse ash waste, palm shells, and a wide variety of other wastes, are used as partial alternatives in the construction sector. One of the most frequently utilized wastes is coconut shells. As an alternative to natural coarse aggregates, coconut shell is used. Nowadays, coconut shell is an actual waste removal challenge all over the world. It releases dangerous compounds like atmospheric carbon dioxide and methane whenever we consume it, which has a significant negative influence on our ecology. Today, coconut shell is a popular choice for coarse aggregate. Prior studies have demonstrated that coconut shells can be utilized as an aggregate that is lightweight and can save on construction material prices [3].
from natural aggregate. In emerging nations like India, the use of natural resources is continuously declining due to rising construction. There is a great demand right now for substitute materials for manufacturing concrete. Limitations on natural and local sources of trash disposal, as well as environmental issues, are becoming more and more significant. Coarse aggregate is a crucial element of the concrete mix for several building projects involving the building of homes and the development of infrastructure. The use of conventional aggregate must be reduced, and we must find alternative building materials such as recycled aggregate, recycled rubber tyres, ceramic waste, granite waste, coconut shell, palm kernel shell, e-plastic waste, palm kernel shell, waste glasses, etc. Coconut shell waste has the potential to be utilized as a coarse material in concrete. Coconut shell is an agricultural and industrial waste that presents significant management and disposal issues. This has raised serious concerns about environmental damage. Natural coarse aggregate can be substituted with waste from the coconut industry. Coconut shells could be used as a substitute for coarse aggregate to help with the issue of a lack of readily available resources because it is also cost-effective and environmentally beneficial. Making use of such materials also helps with disposal problems. The primary objective of this review study is to determine whether using coconut shells as a substitute for coarse aggregate in the production of light-weight concrete is feasible.
2. WASTE COCONUT SHELL Coconut shell is a palm-related agricultural trash that may be acquired from various temples and coconut oil producers. Coconut is cultivated in over 90 nations. They are widely available in Asia, Africa, and America. The first coconuts are thought to have appeared in Southeast Asia [4]. In addition to the fact that it is a widely accessible agricultural waste from nearby coconut enterprises, it also causes significant disposal concerns for the local ecosystem. In less developed nations where there is an excess of rubbish made from coconut shells, the waste from those shells could be used as a viable replacement material in the construction sector. In addition to bringing down the price of construction materials, this will also serve as a way of disposing of trash [5].
Key Words: Concrete, Coarse Aggregate, Coconut Shell, Lightweight Concrete.
1. INTRODUCTION Any improvement to a structure must include concrete. Aggregate, which will be little, is one of the real pieces employed in the significant manufacture of concrete. Find alternatives to natural aggregate to help the development movement. Many investigations are being conducted to develop alternative materials for the manufacturing of concrete. On the other hand, the issue of strong garbage is gradually expanding, while the issue of removal is also expanding as a direct result of the lack of dump site transparency [1]. A huge number of natural resources are used in the production of concrete. It is crucial to implement engineering approaches that concentrate on the preservation of natural assets and energies as a step to

3. COCONUT SHELL UTILIZED AS A COARSE AGGREGATE Coconuts are readily available in the environment, and since their shells do not decompose, they can be simply used in concrete, allowing them to meet almost every one of the properties of the initial kind of concrete. The construction sectors in affluent countries have recognized several Lightweight aggregates, which are manmade and natural materials that have substituted traditional aggregates,
