Using Coconut Shells to Replace Some of the Coarse Aggregate

Abstract

Massive buildings are being made as part of the urbanization and development process as it grows daily. In terms of stress, steel is superior to concrete because it is lighter. Even yet, using steel alone to build a structure is not recommended. Concrete is less expensive than steel. Thus, concrete is the material of choice for construction. Cement, fine aggregate, coarse aggregate, and water are the ingredients required to build concrete. More coarse aggregate is used than other ingredients in the creation of the concrete mix. Better and stronger aggregates are obtained by deeper excavation. Because the parent rock from which coarse aggregates are extracted determines their strength. Thus, the price of coarse aggregate is rising quickly. Coconut shells are used as a partial substitute for coarse aggregates in order to lower the expense and deeper excavation required. Using coconut shells as aggregates minimizes the agricultural waste that is generated from the shells. Because these materials are lightweight, light weight concrete is produced. The cost of building materials is increasing daily these days due to the rising use of concrete. One of the most crucial components of concrete is coarse aggregate. Because coarse aggregate requires deeper excavations, their cost rises. Thus, coconut shells from agricultural waste are chosen to replace some of the coarse aggregate. The amount of waste material made from coconut shells grows daily. When these are used as aggregates, they become less waste. Concrete made from coconut shell is lightweight since it is a lightweight material. In place of coconut shells, coarse aggregate makes up 0%, 5%, 10%, 15%, 20%, and 25% of the mixture. The coconut shells that are utilized in this measure less than 20 mm. Cubes are created in different sizes. After seven, fourteen, and twenty-eight days, specimens are tested.
