Determining the content of steel furnace slag in asphalt
Steel furnace slag is mainly composed of a CaO(MgO)-Al 2 O 3 (Fe 2 O 3)-SiO 2 ternary system composed of elements such as calcium, magnesium, aluminum, iron, and silicon. The properties of the main chemical components are as follows [11], [12]:. 1. Fe 2 O 3 accounts for 10–20 % of the overall content. It is often an indispensable element in 12.1. Introduction. Blast furnace slag (BFS) which is defined “as the non-metallic product consisting essentially of silicates and alumina silicates of calcium and other bases, that is developed in a molten condition simultaneously with iron in a blast furnace” by ASTM C 125-16 (2016) has been widely used in construction industry for more than 80 Blast-furnace slag ScienceDirect

The use of waste is rapidly becoming a supra-disciplinary field in most parts of the world where the use of industrial wastes like fly ash, granulated steel slag, silica fume, and waste fibers in construction has become very popular since the last half of the 20 th century. Other forms of industrial wastes are also re-used even for more sensitive After the accumulation in recent years, the current number of waste blast furnace slag in China is huge. By 2020, the total amount of industrial solid waste in China will reach 3.787 billion tons, The Lhasa method (RASA) water granulated slag treat-ment system was developed by Nippon Steel Pipe and the British trading company RASA Comprehensive utilisation of blast furnace slag Taylor

Minerals Free Full-Text Blast Furnace Slag, Post-Industrial Waste
Blast Furnace Slag is a post-industrial material and is exported in tanks to heaps as a waste material after smelting in the blast furnace. This material is characterized as containing many minerals, mainly silicates and calcium and magnesium aluminosilicates [ Blast furnace slag (BFS) is a particularly interesting anthropogenic material. This material is a byproduct of steel mills, which is deposited in slag dumps at the end of the process [ 5, 6 ]. The slag cooling technique impacts the type of generated slag, which leads to further dividing of the BFS.Geotechnical and Environmental Assessment of Blast Furnace Slag

A by-product of the production of cast iron in cupola furnaces is cupola slag. Its amount is 40–80 kg per 1 tonne of the produced cast iron, and that is one of the reasons why this material is not as favoured as, for example, the blast-furnace slag.
