Abstract
AbstractThis study presents the use of sawdust ash as a substitute in the production of sustainable building materials. Inappropriate dispose of wood-waste causes serious environmental problems as it results in atmospheric degradation, emissions of greenhouse gases and the destruction of aquatic and organic products. This review article combines research results from past studies into the usage of sawdust as an alternative for essential elements in construction composites. The result of this study shows that structural concrete can be manufactured with compressive strengths more than 20 MPa by replacing moderately 5–17% of the sand with sawdust or 5–15% of the cement with sawdust ash. By partially substituting sawdust that ranges between 10 and 30% of sand used in the production of blocks and bricks, sawdust blocks and bricks having compressive strengths greater than 3 MPa can be created. According to the findings of this study, sawdust has the potential to make construction composites that are strong, absorb water, and have an elastic modulus that meet international standards. The study concludes that sawdust composites are intriguing due to having hushed heat conductivity, a prominent sound absorption, as well as efficient sound wadding. From the findings, it is demonstrated that an increase in the utilization of sawdust for construction purposes will reduce the possibility of sawdust as a pollution to the environment, and will also ease the costs of disposal.
