Slag from iron and steel metallurgy can be divided into the blast furnace slag and ladle slag (ladle slag are divided into furnace slag and ladle slag). Slag is a by product of the metallurgical industry and it is the subject of several research. Slag can´t be considered as waste material. Slag is a valuable resource because it has a suitable raw material composition. Most of the produced slag is currently utilized material. However a significant proportion of slag is still land filled. Currently, there are several ways of utilization blast furnace slag and steel slag. Utilization of granulated blast furnace slag is satisfactory. Blast furnace slag is used in the production of cement or concrete. Use of steel slag is difficult and its applications bring a lower value. Slag from steel furnaces is usually processed in less valuable stones. For a specific application slag is besides her origin critical chemical and phase composition, method of processing but also other factors such as its time of land filling. This article focuses causes of instability slag volume. Next article will be also paid attention blast furnace slag, ladle slag and used periklas (MgO).Keywords: volume stability, ladle slag, blast furnace slag, sand bath, use periklas (MgO)
