In developing countries, abundant agricultural and industrial wastes are discharged; these wastes can be used as potential materials or replacement materials in the construction industry. Malaysia is the world’s largest producer of palm oil in the industry. Since palm oil clinker is abundant, lots of attempt have been made to investigate the possible use of this material, especially in the field of construction more so, as concrete is one of the most versatile construction materials. This agricultural waste, being referred to as Palm Oil Clinker Incinerated By-products (OPIB), can totally replace the stone aggregate in concrete mixtures. In this research, the focus is on the strength development of OPIB concrete. Tests have been conducted to investigate the effect of using OPIB aggregate, on the engineering properties of concrete in order to determine the optimum mix proportion of lightweight concrete, using different OPIB of aggregate size. In the tests, the aggregate is graded and then, the mix proportion of this lightweight concrete is determined by a trial of the mix. Finally, the properties of fresh and hardened concrete tests were determined.
