(PDF) Effect of Sawdust as Fine Aggregate in Concrete,
Sawdust can be used as alternative substitute for fine aggregate in concrete production [8, 10]. Sawdust should be washed and cleaned before use as concrete constituent because of large amount of bark which can affect setting and hydration of cement. Concrete obtained from sawdust is a mixture of sawdust, gravel with certain percentage of water to entrance the workability and full hydration of the cement which help in bonding of the concrete.

Like all light weight aggregate, concrete made from shell may be useful for thermal insulation, in the making of pre-stressed concrete (Anthony, 2000). Sawdust as an aggregate in concrete: Sawdust can be used as alternative substitute for fine aggregate in concrete production. SawdustEffect of Replacement of Fine and Coarse Aggregate by,,Sawdust was used to replace fine aggregates from 0% to 50% in steps of 10%. Concrete cubes measuring 150 x 150 x 150mm were cast and their compressive strengths evaluated at 7, 14, 21 and 28 days. Increase in percentage of sawdust in concrete cubes led to a corresponding reduction in compressive strength values. From the results, the optimum sawdust content was obtained at 10%
