BOF slag is the by-product of steel manufacture. Accoording to the process, theby-product includes Blast-Furnace Slag (BF) and Blast Oxygen Furnace (BOF) Slag. The Blast Oxygen Furnace is east to be swell, so it’s usually used on the filler. At this experiment the characteristic of Blast Oxygen Furnace because of contents a lot of iron, so it may have the potential to used on electromagnetic shilding, this is also the keynote of the test. Experiment contains three parts, one is to use different proportions of Blast Oxygen Furnace slag powder, with replaceing with cement weights (0%、10%、20%、30%), and the second one is to use three kinds of thickness(3mm、4mm、5mm), the third one is use two kinds of water-cement ratio, to measure the effectiveness of electrom agnetic shilding, and to probe into whether cement mortar with Blast Oxygen Furnace slag powder ingredient can shild electtomagnetic or not. After researching on cement mortar with Blast Oxygen Furnace slag it can be use in Electromagnetic protection、military use、medical purposes. And I expect this material can be used to domestic architecture, for protecting the health of our life.
