Preparation of Graphite Gangue Wall Body Materials By Solidifying Technique

摘要

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 percent 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 reaction to produce pastes and intensive framework.
