Method for preparing concrete micro-aggregate from high-titanium blast furnace slag
The invention provides a method for preparing concrete micro-aggregate from high-titanium blast furnace slag, and relates to the technical field of blast furnace ironmaking. The high-titanium blast furnace slag comprises high-titanium blast furnace slag micro-powder, the particle size of the blast furnace slag micro-powder is smaller than 5 microns, preferably, the high-titanium blast furnace slag is adopted in the method for preparing the concrete micro-aggregate through the high-titanium blast furnace slag, and the high-titanium blast furnace slag is adopted in the method for preparing the concrete micro-aggregate through the high-titanium blast furnace slag. Comprising the following steps: S1, crushing, screening and deironing the high-titanium blast furnace slag to obtain coarse-particle blast furnace slag with the particle size of less than 40mm; the high-titanium blast furnace slag micro-powder with the particle size smaller than 5 microns can be prepared by adopting a method that high-titanium blast furnace slag is subjected to traditional crushing and airflow grinding, and the high-titanium blast furnace slag micro-powder serves as concrete micro-aggregate, improves the concrete strength and can also serve as filler of high polymer materials such as plastic, rubber and paint, so that the economic value of the high-titanium blast furnace slag is obviously improved, and the economic value of the high-titanium blast furnace slag is increased. And the field of comprehensive utilization of the high-titanium blast furnace slag is widened.
本发明提供一种高钛型高炉渣制备混凝土微骨料的方法，涉及高炉炼铁技术领域。该一种高钛型高炉渣，包括高钛型高炉渣微粉，所述高炉渣微粉的粒径小于5μm，优选的，一种高钛型高炉渣制备混凝土微骨料的方法，采用权利要求1所述的一种高钛型高炉渣，包括以下制作流程：S1、将高钛型高炉渣经破碎、筛分、除铁后得到粒径小于40mm的粗颗粒高炉渣。通过采用将高钛型高炉渣进行传统破碎配合气流研磨的方法，可以制备粒径小于5微米的高钛型高炉渣微粉，作为混凝土微骨料，提高了混凝土强度，也可以作为塑料、橡胶及涂料等高分子材料的填料，使高钛型高炉渣的经济价值明显提高，拓宽了高钛型高炉渣综合利用的领域。
