Cementing material and preparation method thereof
The invention belongs to the technical field of building corrosion prevention, and particularly relates to a cementing material and a preparation method thereof.The cementing material comprises a carbon nanomaterial and Portland cement, the carbon nanomaterial comprises at least one of carbon dots and carbon dot modified graphene oxide, and the carbon dots, the carbon dot modified graphene oxide and the Portland cement are compounded to form the cementing material. Compared with ordinary Portland cement, the cement provided by the invention has the advantages that the chloride ion curing rate of the cementing material is greatly improved by more than 5 times, the corrosion resistance of the cementing material is greatly enhanced, and the service life of the cementing material after curing is prolonged.
本申请属于建筑防腐技术领域，尤其涉及一种胶凝材料及其制备方法，上述胶凝材料包括碳纳米材料和硅酸盐水泥，所述碳纳米材料包括碳点、碳点改性氧化石墨烯中的至少一种，将碳点、碳点改性氧化石墨烯与硅酸盐水泥复合，不需要额外添加分散剂或者其他添加剂，大大提高了胶凝材料的氯离子固化率，与普通硅酸盐水泥相比，其氯离子固化率可提高5倍以上，大大增强了胶凝材料的防腐性能，延长了胶凝材料固化后的使用寿命。
