Pervious concrete, or "porous concrete," is characterized by its sand-free mixture. Therefore, it is classified as a type of lightweight concrete. Due to the trend towards using sustainable materials to preserve the environment by getting rid of waste and reducing carbon dioxide production, four mixtures were prepared in this research. The first mixture was used to control the mixture. Second, 30 % of the volume of coarse aggregate was replaced with brick waste aggregate. After that, 10% of the Cement was replaced by metakaoline. Finally, carbon fibre was added by 1% of the weight of the Cement. Compressive strength, Density, and flexural strength tests were conducted. The results of the tests demonstrated that the previous concrete mixture, including 30% crushed brick, 10% metakaolin, and 1% carbon fibres, had greater compressive strength at 7 and 28 days of curing than a mix containing 30% brick waste. The Density of pervious concrete, which contains waste, decreased compared to that of the original concrete. Adding carbon fibres led to a slight improvement in compressive strength and a good improvement in the flexural and splitting tests compared with the mixture containing brick waste and Metakaolin. |
