Zusammenfassung: | The invention relates to the field of cement materials, and particularly discloses a chromium reducing agent and a cement-based mixture using the chromium reducing agent. The chromium reducing agent comprises the following raw materials in parts by mass: 17-26 parts of a component A and 6-8 parts of sodium nitrite, wherein the component A is one or two of 3-methylamino-1, 2-propylene glycol and 3-diethylamino-1, 2-propylene glycol. The chromium reducing agent is good in chromium reducing effect and good in environmental oxidation resistance.
