The concrete technology has been growing significantly since years ago especially in Indonesia’s construction. Therefore, Indonesia needs new innovation of concrete technology to solve the problem for the availability of concrete material. Indonesia is known as the largest producer of crude palm oil (CPO) in the world. Oil palm shell (OPS) is one of the solid wastes produced in crude palm oil industry that can be used as concrete materials. This paper presents the experimental results of a research project to produce structural lightweight concrete using oil palm shell (OPS), as a coarse aggregate. This experimental was investigating the effects of adding silica fume, fly ash, and superplasticizer for the compressive strength and flexural strength of the OPS lightweight concrete. It was found that OPS lightweight concrete has compressive strength up to 23.90 MPa in 28-days and flexural strength up to 2.54 MPa in 28-days. This experimental concluded that OPS lightweight concrete has a good potential as a lightweight coarse aggregate and low-cost housing construction in Indonesia.
