ABSTRACT
A large amount of marble waste (MW) is being produced by marble industry every year, while coconut fibers (CF)
are abundantly available in tropical regions. These two raw materials can be used as a partial cement replacement
in concrete. In this research, a combination of CF and marble dust (MD) has been investigated. Cubes were formed
for compressive strength and beams were formed for flexure strength tests using different percentages of cement, CF
and MD. It has been found that the combination affects the strength of concrete. It was observed that a total of 5%
replacement of cement with CF and MD produced an increase in strength. More replacement results in a decrease in
strength. Results showed that CF and MD can act as partial cement replacement, when used in specific proportions.
