Engineering properties of coconut shell lightweight concrete: A comparative study

Alireza Javadi Pordesari, Payam Shafigh, Zainah Ibrahim and Muhammad Aslam

Abstract

A vast amount of natural resources are required to produce concretes due to industrialisation and urbanisation, indicating that large quantities of raw materials are being utilised worldwide. The use of industrial wastes as an aggregate in concrete is highly recommended to promote sustainable development by reducing the consumption of natural resources. Agricultural wastes are available in large amounts, thereby making them an acceptable and reliable solution for aggregate in concrete. In this study, natural aggregates, such as coconut shell and oil palm shell, were replaced with normal coarse aggregate. The properties of concrete, such as workability, density, compressive strength in different curing regimes, splitting tensile strength, Young

Key Words

agricultural waste; curing; drying shrinkage; mechanical properties; structural lightweight aggregate concrete
