The feasibility of producing graphite gangue wall body materials was discussed by the experiments of four kinds of hardeners solidifying graphite gangue . The result demonstrates that the physical performances of graphite gangue solidified brick samples with 8% hardener D reach the senior grade or the special grade in JC422 - 91. The study of solidification mechanism indicates that the hardeners produced pastes while being hydrated. In addition , they can activate the mineral compositions in clay to join in the reacttion to produce pastes and intensive framework.
