The amount of wastage produced in the construction industry is increases. The revolution making alterations to conventional concrete had been introduced. Industrial wastage such as fly ash, sawdust, and sludge are often used to replace material in the concrete mix, by that, the value of sustainability increase. Reusing waste materials can reduce renewable and non-renewable resources such as sand and water. This study emphasis the mechanical properties of the lightweight concrete regarding the replacement of material, sawdust into the concrete mix by 0% (control sample), 10%, 20% and 40% for grade 30 N/mm2. The objectives for this study are to determine the mechanical behavior of concrete mix with partial replacement of recycled fine aggregates, to determine the concrete properties consolidating recycled tropical wood sawdust, and to identify the optimum percentage partial replacement of recycled tropical wood sawdust in the concrete mix. For fresh concrete, slump test were performed to determine the workability of the concrete while for hardened concrete tests were compressive strength test, water absorption test and density test. The tests were carried out at the age of 7 days and 28 days. The result shown that 10% of sawdust replacement in the concrete mix recorded the highest amount of compressive strength, lowest water absorption and highest density compared to the control sample.
