摘要: Industrial by-products generated in the steel manufacturing are successfully used as raw materials production of construction materials. However, slags, due to their nature and composition, can cause undesirable side-effects mortars concretes. The reactive components LFS EAFS affect stability cement matrix. This situation may be prevented by an adequate pre-treatment slag stabilization a study possible reactions within its mineralogical components, ensure over time. In this work, experimental process is shown evaluate behaviour under adverse environmental conditions when aggregates manufacture for masonry, such presence humidity, high temperatures (80°C) alkali-silica alkali-silicate reactions. results show acceptable normal (20°C). formation crystalline acicular structures were observed which degraded internal structure manufactured with LFS.
