Behaviour Analysis of Light Weight Concrete with Coconut Shell as a Partial Replacement of Coarse Aggregate

Abstract

Abstract: Concrete is the most widely used material in the world for construction, more than any other commodity. It is also the second-most used material after water in the world. In concrete, aggregates are the most abundant component by volume and are naturally low in carbon, and the demand for natural coarse aggregate is increasing in construction activities. Using light aggregate materials as coarse aggregates can help reduce the environmental impact of construction projects. Lightweight aggregates in concrete have a low density, which gives it several other properties like low self-weight and good thermal and acoustic insulation. Coconut shells can also be used as a lightweight aggregate in concrete. Coconut shell, a natural by-product of the coconut industry and a renewable resource, is one potential lightweight aggregate. In this experimental investigation, coconut shells were used as a partial replacement for coarse aggregate in lightweight concrete at 0%, 10%, 20%, 30%, and 40% of the concrete mixes, whereas this paper presents practical work on mechanical properties such as compressive strength and split tensile strength in the concrete.
