Cement compound is an important component of building materials. Its microstructure and physical and mechanical properties are affected by admixture. Taking cement compound as the object of study, this study explores the effect of cement compound on the microstructure of cement concrete by adding different contents of coal gangue fine aggregates, as well as reveals the action mechanism of active coal gangue on cement concrete. When the content of coal gangue fine aggregate is 20%, the microstructure is compact. The relationship between compressive strength and axial compressive strength of coal gangue cement concrete is established by testing the compressive property of coal gangue cement compound (CGCC). The stress-strain curve of spontaneous combustion and non-spontaneous combustion of CGCC is obtained, and the compression constitutive model of CGCC is proposed.
