sawdust concrete. 2. Current Trends and Limitations The experimental study of the partial and full replacement of fine aggregates by sawdust dates back to the 1980s' [7]. The experimental studies have incorporated the use of sawdust in concrete composition [13, 14, 15] to sawdust concrete block [16], and pavement material modification [17].
The concrete blocks are using coarse aggregate, fine aggregate, cement, water and sawdust to mix it. Using some percentage of sawdust in place of sand in concrete for example replaces 10%, 15%, 20% of sawdust instead of sand and remaining is same.
