I wish that in addition to being a Pro- fessional Engineer I was also a communications expert. My principal task this morning, and yours after this meeting, is to convince a wide variety of individuals that steel industry slags are a high quality material that can be used for many purposes; and that their use can significantly alleviate some of the problems facing engineers, public officials, and the general public in our countries. By actual in- place performance over a long period of time steel industry blast furnace slags have proven that they are as good as the best natural aggregates, and better than some, for any type of construction or purpose for which natural aggregates are used. Steel furnace slags have many unique favorable characteristics and prop- erties when compared to other types of aggre- gate even though they cannot be used for all types of construction. We have the facts, all we have to do is present them to the right people in the proper manner.
