    Compressive Strength of Concrete Using Sawdust as

    2016-9-9  A concrete mix of ratio 1:2:4 by volume was used as control; to which the properties of the other mixes were compared. Sawdust was used to replace sand at percentages of 25%, 50%, 75% and 100% by volume. A water cement ratio of 0.55 was adopted. Concrete was produced by mixing the constituent raw materials in an electric concrete mixer.
