Alternatives For Sand As Fine Aggregate

Two sets of mixture with six samples of each for a total of 12 samples were prepared and tested. Findings of the study revealed that the concrete mixture using sawdust is comparable to the compressive strength of concrete mixture using sand as fine aggregate. Thus, the sawdust can be considered as an alternative for sand as fine aggregate.
