Here’s why steel slag aggregate is an ideal solution for building road

14 Mar 2022 CW Team

Steel Slag is one of the major solid wastes of steel making processes in an integrated steel plant. During steel making through furnace route where carbon rich molten pig iron is converted in to steel, all the unwanted impurities are removed through various fluxing agents as steel slag so that the maximum recovery of iron through lowering the carbon content in the alloy can be achieved. According to Indian Mineral Book 2018, steel slag output is approximately 20-30 per cent by mass of the crude steel production in the country, which yields around a total 18.5 million tonne of solid steel slag production annually in the country. This quantity is slated to increase to 30 million tonne by 2030 with a likely increase in the production of steel as per the National Steel Policy 2017. A majority of steel slag after metal recovery ends as waste dump or as land fill material. Among all the solid/liquid wastes, slags generated at iron making and steel making units are in such a large quantity that management of slag has become a critical component of steel production. With increasing capacities, the mechanism for disposal of large quantities of slag that get generated have gained traction as the environmental issues that it could evoke can become critical for steel makers.

In India, a huge quantity of good quality natural aggregates are required every year for the construction of new roads and for the maintenance of distressed road networks. Steel slag, which is rich in iron content…
