This study investigated the effect of sawdust as partial replacement for Fine Aggregate in light weight concrete
production. Sawdust was used to replace Fine Aggregate from 0% to 40% in steps of 5%. 150 x 150 x 150mm concrete
cubes were cast for each replacement level, the concrete was cured and the compressive strengths were determined at
7, 21 and 28days curing period respectively. Increase in percentage of sawdust in concrete led to a constant reduction
in the compressive strength values with a corresponding reduction in weight. From the result obtained, 5% replacement
of Fine Aggregate with sawdust gave a maximum compressive strength 13.11 N/mm2. It was however concluded that
the optimum replacement level of 5% can be used as plain concrete for blinding works.
