Abstract: Coal Gangue has become one of the main solid wastes produced in the development of Chinese industry. Massive coal gangue caused serious damage to the ecological environment in China. The conventional treatment of coal gangue is costly and can not effectively reduce the impact on the environment. Based on the previous research of experts and scholars in the industry, this paper carried out a series of mechanical properties and durability tests of concrete to explore the applicability of coal gangue concrete as coarse aggregate in the foundation of transmission tower.
