In order to rationalize the consumption of graphite tailing sand and reduce its pollution environment—with sodium silicate being a commonly used activator for improving strength concrete composites—in this study, joint effects (SS) tail (GT) on frost resistance high-performance mortar (GT-HPM) were investigated. Experiments conducted evaluate bulk density, water absorption, compressive strength, speed sound, working performance status GT-HPM before after freezing thawing at different SS dosages GT substitution rates. The microstructural properties also analyzed by X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM/EDS). results showed that 4% doping improved more obviously. Moreover, with an increase in rate, mechanical increased firstly then decreased, best was obtained when rate 20%. At 6% doping, gradually decreased rate. FT-IR testing there no significant change type hydration products used, Si–O–T absorption peak average bond length GT-4 largest. promoted generation products. Microstructural analysis reaction; addition, appropriate amount pore structure HPM, resistance, provided fundamental insights subsequent comprehensive utilization sand.
