Preparation method of modified superfine granulated blast-furnace slag micropowder
The invention relates to the technical field of building materials, in particular to a preparation method of modified superfine granulated blast-furnace slag micropowder, which comprises the following steps: drying granulated blast-furnace slag, grinding the granulated blast-furnace slag in a vertical mill, grinding the ground granulated blast-furnace slag in a horizontal ball mill, spraying a composite slag grinding aid and a composite slag exciting agent in the grinding process, and uniformly mixing the ground granulated blast-furnace slag and the composite slag exciting agent to obtain the modified superfine granulated blast-furnace slag micropowder. And finally, the modified superfine granulated blast-furnace slag micro powder is obtained, two mills are selected for grinding, and meanwhile, the composite slag grinding aid and the composite slag exciting agent are added, so that the prepared modified superfine granulated blast-furnace slag micro powder is larger in specific surface area and higher in activity index, and the potential activity of the modified superfine granulated blast-furnace slag micro powder can be brought into full play.
本发明涉及建筑材料技术领域，具体涉及一种改性超细粒化高炉矿渣微粉制备方法，首先对粒化高炉矿渣进行烘干，然后将其放入立式磨机中进行粉磨，再放入卧式球磨中进行粉磨，并在粉磨过程中喷入复合矿渣助磨剂和复合矿渣激发剂，最后获得改性超细粒化高炉矿渣微粉，选用两种磨机进行粉磨，同时添加复合矿渣助磨剂和复合矿渣激发剂，使得制备而成的改性超细粒化高炉矿渣微粉比表面积更大，活性指数更高，使得它的潜在活性能充分发挥。
