Preparation process of modified steel slag micro powder as well as modified steel slag micro powder and concrete prepared by preparation process
The invention discloses modified steel slag micro powder, which is prepared from steel slag by a hot disintegration process, and is ground by rod milling, ball milling and vertical milling processes.A modifier comprises the following main components: anhydrous calcium sulphoaluminate, hemihydrate gypsum and oxalic acid. The modified steel slag micro powder can equivalently replace S95 mineral powder, so that the working performance and the mechanical performance of the steel slag micro powder concrete are not lower than those of concrete using the S95 mineral powder; compared with common concrete, the concrete adopting the modified steel slag micro powder has the advantages that the dosage of the steel slag micro powder is large, the compactness and the mechanical property of the concreteare improved, meanwhile, the utilization additional value of solid waste is increased, and meanwhile, the environmental protection problem is solved.
本发明公开了一种改性钢渣微粉，所用钢渣为热闷工艺产生，使用棒磨、球磨、立磨工艺研磨；改性剂主要成分为无水硫铝酸钙、半水石膏、草酸。本发明所述的改性钢渣微粉，可以等量取代S95矿粉，使钢渣微粉混凝土工作性能与力学性能均不低于使用S95矿粉的混凝土；采用该改性钢渣微粉的混凝土相较于普通混凝土，钢渣微粉用量较多，在改善了混凝土的密实性与力学性能的同时，也提高了固废的利用附加值，同时解决了环保问题。
