description The invention provides a mineral preservative for inhibiting corrosion to concrete and a use method of the mineral preservative. According to the mineral preservative, SiO2 and Al2O3 which serve as main components react with Ca(OH)2 generated after cement hydration, and a hydraulic substance is generated. Superfine powder of the mineral preservative is adopted to replace part of cement, the content of system alkali is reduced, and an alkali-aggregate reaction is inhibited. Besides, the extremely narrow particle size distribution of the superfine powder of the mineral preservative can fill gaps among other cementing materials better, the grading of the cementing materials is improved, the cementing material system is more compact, the compactness of set cement is improved, and the corrosion resistance of the concrete is higher. In the actual preparation process of the concrete, a mineral admixture of the superfine powder of the mineral preservative and fly ash replaces a part of cement in the cementing materia
