Chloride ion-resistant magnesium oxide-based cementing material and preparation method thereof
The invention discloses an anti-chloride-ion magnesium oxide-based cementing material and a preparation method thereof, magnesium hydroxide, ferrous chloride and ferric chloride are stirred in water to enable the components to contain nano magnetic ferroferric oxide, and then the anti-chloride-ion magnesium oxide-based cementing material is obtained through calcination in a protective atmosphere. A compact hydrate is formed during hydration, and the magnetic nano ferroferric oxide is gathered on the surface of steel to form a protective film, so that a steel part in the concrete is prevented from being corroded by chloride ions.
本发明公布了一种抗氯离子氧化镁基胶凝材料及制备方法，将氢氧化镁，氯化亚铁和氯化铁，在水中搅拌使组分中含有纳米磁性四氧化三铁，再通过保护气氛煅烧得到抗氯离子氧化镁基胶凝材料。水合时形成致密的水合物，磁性纳米四氧化三铁集聚在钢铁表面形成保护膜，防止混凝土中的钢铁件被氯离子腐蚀。
