Comparative Study on Partial Replacement of Fine Aggregates with Wood Powder and Quarry Fines in Cement Blocks

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.
