Self-igniting gangue concrete from C15 to C40 was successfully produced with fine and coarse aggregate of coal gangue through mix design method of lightweight aggregate concrete. It concluded that Self-igniting gangue concrete with reasonable grading can reach to the target strength. The basic properties of Self-igniting gangue concrete between Coal Gangue Portland cement and Portland cement were investigated, and mechanism was analysis. The coal gangue content was from 705 to 80% in the concrete. The technology can not only relief the scarcity of natural aggregate, but also employed the solid waste, and it was suitable for sustainable development in 21 century.
