SLAG TYPES AND UTILIZATION AREAS

The utilization of slag in Turkey is behind of developed countries. The resulting slag mountains occupy space and cause environmental problems. Environmental problems such as air, soil and water pollution affect human health and plant growth. Increasing the use of slag is an important way to solve these problems. Metallurgical smelting slag is not only considered as waste, but it can also be considered as a valuable secondary raw material that can be used both in metallurgical processes and in other industrial applications. Blast furnace slag and steel slag constitute a significant portion of the total slag. Although iron-containing slags are usually used as a secondary building material, other non-iron slags are less frequently used due to their toxic character and environmental risks. Replacement of some or all of the natural aggregates with slag byproducts may provide significant environmental and economic benefits by protection raw materials and reducing waste materials. In this paper, slag types and their utilization areas were discussed
