Multitechnique investigation of concrete with coal gangue

Although the research of coal gangue as construction aggregate has been conducted for many years, the fundamental knowledge about the links between the microscopic properties of coal gangue and the macroscopic properties of concrete has not been discovered yet. In this paper, gravel was entirely replaced by coal gangue to improve the utilization rate. The compressive strength, fluidity, and compactness of concrete were studied to explore the...
