Key Words: Compressive strength, Concrete, Sawdust, Light weight concrete, Fine Aggregate. 1. INTRODUCTION Concrete is a mixture of cement, fine and coarse aggregates and water, which are mixed in a specific proportion to get a particular strength. Both cement and water react together chemically to form a paste, which binds the aggregate

concrete and to find the saw dust content required to attain maximum compressive strength. Adding saw dust to the mix by partially replacing fine aggregate to cast concrete specimens. The saw dust have to add by 10, 20 & 30 percentage of weight of the fine aggregates to compare with conventional 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.

Fine aggregates are essentially any natural sand particles won from the land through the mining process. Fine aggregates consist of natural sand or any crushed stone particles that are ¼" or smaller.This product is often referred to as 1/4'" minus as it refers to the size, or grading, of this particular aggregate.
