Partial Replacement of Fine Aggregate with Sawdust for Concrete: A Research

ABSTRACT Concrete's significance as a building material is growing daily. Sand is a primary fine aggregate that gives concrete strength and greater component adherence. It has been difficult for civil engineers to turn industrial waste into useful building and construction materials because of the high demand on the building material industry, particularly in the last ten years due to population growth, which has resulted in a chronic shortage of building materials. It was found that sawdust-containing concrete compacted more effectively than regular concrete when the specimen was cast to test the concrete's compressive strength. Dry porous sawdust might absorb enough water to serve as an efficient internal curing method, absorb extra water in the mixture, and supply the water needed for the cement to hydrate. Sawdust will lower construction costs and address environmental problems because it is already waste. Without compromising the strength of the concrete, using sawdust to replace sand to a degree of 0 to 25% will help reduce the amount of sawdust waste produced in society.
