Palm Oil Clinker as Coarse and Fine Aggregates in Lightweight Concrete

This study presents the investigation of the properties of lightweight concrete (LWC) with the palm oil clinker (POC) as the lightweight aggregates. The investigation began with the characterization of the properties of the POC to ensure its suitability in the production of LWC. The fresh state and mechanical strength of concrete was then compared between normal concrete (NC) and LWC. In comparison with NC, LWC had a maximum decrement of about 25%, 37%, and 22% for compressive, splitting, and flexural tensile strengths, respectively. It has been demonstrated that the properties of the aggregates used in concrete production have a direct influence on the workability and strength of concrete.
