With reference to the steel slag, consider the following statements:1....
Union Steel Minister inaugurated a six-lane highway in Surat made of steel slag -- a first in India.
- The road constructed using 100 per cent steel-processed slag is a real example of converting "waste into wealth" and improving sustainability of steel plants.
- The road has been jointly made by Central Road Research Institute (CRRI) -- a laboratory of Council of Scientific and Industrial Research (CSIR) and ArcelorMittal Nippon Steel (AMNS) India.
- Slag is a by-product which comes out during manufacturing of steel through three processes, namely basic oxygen furnace (BOF) route, electric arc furnace (EAF) and induction furnace (IF).
- This is a breakthrough for the industry as far as utilisation of slag is concerned. Slag was being used only for only landfilling.
- Use of such material in road construction shall not only increase its durability but also help in reducing the cost of construction as slag-based materials have better properties than natural aggregates. The use of steel slag in road construction will also address the shortage of natural aggregates in the country.
Hence both statements are correct.

With reference to the steel slag, consider the following statements:1....
Introduction to Steel Slag
Steel slag is an essential by-product generated during the steel manufacturing process. Understanding its production and applications is crucial for recognizing its significance in various industries, particularly construction.
Statement 1 Explanation
- Steel slag is produced during the steelmaking process through three main routes:
- Basic Oxygen Furnace (BOF): In this method, molten iron is converted into steel by blowing oxygen through it, resulting in slag formation.
- Electric Arc Furnace (EAF): This process uses electric arcs to melt steel scrap, also generating slag as a by-product.
- Induction Furnace (IF): Here, steel is melted using electromagnetic induction, leading to the creation of steel slag.
Thus, Statement 1 is correct.
Statement 2 Explanation
- The use of steel slag in road construction offers several advantages:
- Cost Reduction: Utilizing steel slag can lower material costs since it is often more affordable than natural aggregates.
- Enhanced Properties: Steel slag has superior properties compared to conventional aggregates, such as:
- Higher strength: Provides better durability and load-bearing capacity.
- Improved skid resistance: Enhances safety on road surfaces.
- Better drainage: Helps in effective water management.
These attributes make steel slag a valuable material for road construction. Therefore, Statement 2 is also correct.
Conclusion
In summary, both statements regarding steel slag are accurate. It is produced from various steel manufacturing processes and offers enhanced properties for road construction, leading to cost savings. Thus, the correct answer is option 'C': Both 1 and 2.
