Performance of carbon fibre-reinforced pervious concrete (CFRPC) subjected to static, cyclic and impact loads

ABSTRACT

This study focuses on determining the performance of carbon fibre-reinforced pervious concrete (CFRPC) mixes subjected to static, cyclic and impact loadings. Two single-sized coarse aggregates, namely, 12.5 and 20 mm were used with aggregate to cement ratio and water to cement ratio of 3.54 and 0.35, respectively. The volume fraction of carbon fibre (CF) was varied from 0 to 0.4% at 0.1% intervals. The optimum volume fraction of CF was determined as 0.2% for both aggregate sizes. Slab specimen with 0.2% of CF was found to outperform the conventional pervious concrete slab under static, cyclic and impact loading.
