Abstract: The concrete with different water cement ratio was prepared with slag as binder material and coal gangue as fine aggregate. The effects of water binder ratio, slag content and coal gangue content on the compressive strength and frost resistance of concrete was studied through orthogonal experiments, and the influence of microscopic mechanism on the mechanical properties was discussed. Results showed that the water binder ratio and slag content had a significant effect on the compressive strength, and the effect of coal gangue as fine aggregate was small. The slag and coal gangue content had a significant effect on the frost resistance of concrete, and the effect of water binder ratio was small. In order to improve the compressive strength and frost resistance comprehensively, the optimal mix proportion was water binder ratio as 0.4—0.45, 30% slag content, and 30% coal gangue as fine aggregate. Moreover, the fractal dimension of the scanning electric morphology (SEM) was calcula-ted based on fractal theory. Results showed that the fractal dimension of coal gangue/slag concrete was negatively related to the strength.
