| Summary: | The purpose of this study is to investigate the performance of the concrete pavement contains several percentages of coal bottom ash (CBA). Many power plants produce very large quantity of the coal bottom ash as a waste. The way to get rid of the CBA in very dangerous and could cause hazards to the environment and the surroundings. As using of coal bottom ash can help in solving environmental problems, thus this study is to investigate the possibility of using it as a replacement of fine aggregate in improving the performance of concrete pavement. Concrete specimens prepared containing 0%, 10%, 20%, 30% and 40% of coal bottom ash as a replacement of fine aggregates. This study performed on compressive strength, Porosity, permeability, density and skid resistance. It has been found that the compressive strength decreases with the increase of the coal bottom ash content at early ages. Also, the percentage of the absorption increases as the percentage of CBA content increase. Same as the volume of permeable pore spaces (voids), it also increases with the increase of the CBA content. On the other hand, the density decreases with the increase of the CBA content. Results also show that the British pendulum number increases with the increase of content of the CBA. |
