A global problem of concern is the growing waste generation. Many waste, whether industrial or urban sites, often end up polluting the environment, causing storage problems of certain materials. Furthermore, alternative materials from these waste may be cheaper, often presenting better performance characteristics than conventional materials. Steelmakers, worldwide, are facing a common problem, which is what to do with all of the slag generated in the production of steel. This paper aims to point out the applicability of the use of slag in the construction industry through studies on tecnoligias developed for the slag that is used as addition to ordinary Portland cement and applications in other areas of construction with BENEFITS or not reuse. Studies have been conducted concerning matters that use or may use scrap additions blast furnace to the cement industry. After the study it was found that recycling blast furnace slag in Brazil is practically limited by their recycling in ordinary Portland cement industry. The environmental contribution of this type of recycling is significant. However, several new applications can be developed to better use this waste.
