Check the offer Blast furnace slag As the name suggests, it is produced in a blast furnace during the reduction of metallic iron. Its properties are roughness, roughness, and the color can be from light gray to gray. The habit of the slag is dense to cavernous, fine crystalline or amorphous. After crumbling, it is characterized by numerous sharp edges. Blast furnace slag is lighter than natural aggregates. Its feature is fire resistance and low insulating properties. Due to its cavity, water absorption is higher than for natural materials. Due to the closed porosity, the slag is frost resistant. Converter slag It is produced as a result of steel smelting in a converter, which converts pig iron into steel. Steel slag is processed into grit or road aggregate useful in the production of asphalt mixtures. Converter slag is usually dark gray in color and is a very compact material - similar to basalt. It has a high bulk and specific density. It has high compressive strength, high roughness and low water absorption. Metallurgical slag obtained from various sources has been tested many times in order to demonstrate the level of radioactivity. Research has shown that metallurgical slag can be used in road and building construction without restrictions. Studies of water extracts indicate that metallurgical slag can be discharged into surface waters and soil, except for which the pH is highly alkaline.
