Preparation method of activating agent for increasing mixing amount of steel slag powder in common concrete
The invention discloses a preparation method of an activating agent for improving the doping amount of steel slag powder in common concrete, the activating agent is prepared from ethylene glycol monovinyl polyglycol ether, isomeric acid pentaerythritol ester, sodium hypophosphite, calcium nitrate, sodium silicate and the like, and the activating agent is added in concrete production to solve the problems that the doping amount of the steel slag powder is small in application in concrete; the problem that the steel slag powder is only used in non-structural concrete is solved, it is guaranteed that the concrete with the high-content steel slag powder meets the construction performance and the strength and meets the quality requirement, and the concrete can be applied to a common building structure.
本发明公开了用于提高普通混凝土中钢渣粉掺量的活化剂的制备方法，利用乙二醇单乙烯基聚乙二醇醚、异构酸季戊四醇酯、次磷酸钠、硝酸钙、硅酸钠等制备活化剂，在混凝土生产中加入该活化剂解决钢渣粉在混凝土中应用中掺量少，泌水、离析以及仅用在非结构混凝土中的问题，保证高掺量钢渣粉的混凝土满足施工性能和强度满足质量要求，该混凝土能够应用于普通建筑结构中。
