Abstract: In order to explore the mechanical properties of the coal gangue-steel slag-ore powder mixture without alkali initiator, the solid waste materials coal gangue, steel slag and mineral powder produced in Handan Area were taken as the research objects, and the mechanical properties of the mixture were studied, and the test showed that the mixture had good mechanical properties and high engineering application value. The regression analysis model is established by Minitab to obtain the relative content and the regression equation between the admixtures, which can effectively reveal the relationship between the target strength value and the relative adhesion, and can provide the mixture ratio according to the actual project. XRD and SEM test methods were used to analyze the strength formation mechanism of the mixture in the alkali-free stimulant environment, and the phase composition and microstructure of the sample were analyzed and studied, and the results showed that the three admixtures of the mixture could generate a large number of overlapped and densely structured gel materials, so that the mixture had good mechanical properties.
