**6. Future Research Directions**

This study employed the use of fired clay solid bricks to prepare the crushed brick aggregates. The density of these bricks is very low, i.e., 120 kg/m<sup>3</sup> . In actual practices, there are different types of bricks with varying densities. Future studies are recommended to consider crushed brick aggregates with higher densities to further investigate the role of LC-GFRP composites to enhance the strength of confined concrete.
