ABSTRACT
This project aimed to investigate the potential of using wood powder and quarry fines as
partial replacements for fine aggregates in cement bricks. The study included a
comparative analysis of the mechanical properties and water absorption of cement bricks
made with varying proportions of wood powder and quarry fines. Compressive strength
tests were carried out on the bricks for 7, 14, and 28 days. Water absorption tests were also
conducted on the bricks after 7, 14 and 28 days.
The results of the study indicated that the use of wood powder and quarry fines as partial
replacements for fine aggregates in cement bricks led to a decrease in compressive
strength and an increase in water absorption. However, it was observed that the reduction
in compressive strength was not significant, and the water absorption values were still
within acceptable limits for building materials. Additionally, the cost analysis showed that
the use of wood powder and quarry fines could lead to cost savings in the production of
cement bricks.

CONCLUSION
Both wood powder and quarry fines can be used as partial replacements for fine
aggregates in cement blocks.
 Up to 40% replacement of fine aggregates with wood powder can be made
without significantly compromising the compressive strength of the cement
blocks, while up to 30% replacement of fine aggregates with quarry fines is
possible.

 The cost savings are particularly significant when using wood powder or quarry
fines as a replacement for a higher percentage of fine aggregates, such as 40%.
 The optimal replacement percentage for wood powder and quarry fines appears to
be around 30-40%, as higher percentages can result in reduced strength and
increased water absorption.
 Despite the cost savings, it is important to consider other factors such as strength
and water absorption when deciding on the optimal percentage of replacement for
wood powder or quarry fines.
