Production of the recycled coarse aggregate from concrete scraps

Japan, the recycling ratio of concrete scraps has been kept over 95% after the Law for the Recycling of Construction Materials was enforced in 2000. On the other hand, it is predicted to be difficult to keep this higher recycling ratio in the near future because concrete scraps increase rapidly. Therefore, new way to reuse concrete scraps must be developed. In this paper, a new method for recycling coarse aggregate from concrete scraps has been developed and demonstrated. The system includes a Marx generator and a point to hemisphere mesh electrode immersed in water.
