Highlights steel slag tech in road construction
Union Minister of State for Steel Mr. Faggan Singh Kulaste, has emphasized on the imminent use of steel slag technology.
Speaking at a recent industry meeting organized under the ‘One Week One Lab’ program of the Council of Scientific & Industrial Research (CSIR)-Central Road Research Institute (CRRI), the minister said that the Steel Slag Road technology of CSIR-CRRI is playing an important role in realizing the Prime Minister Mr. Narendra Modi’s mission of ‘Waste to Wealth’.
Mr. Kulaste informed that India is the second largest steel-producing country in the world and about 19 million tonnes of steel slag is generated in the country as solid waste, which will increase to 60 million tonnes by the year 2030.
It is estimated that about 200 kg of steel slag is generated in one tonne of steel production.
Due to the non-availability of efficient disposal methods for steel slag, huge piles of steel slag have come up around the steel plants, which have become a major source of water, air, and land pollution.
The 1st road made with steel slag road interpretation technology in Surat, Gujarat, has become famous for its technological excellence at national and International levels.
About one lakh tonnes of steel slag aggregate has been used in its construction, under the technical guidance of CRRI at the Hazira plant of ArcelorMittal Nippon Steel. No natural ballast of any kind has been used in the construction of this road.
Border Roads Organization has also constructed a steel slag road in Arunachal Pradesh along with CRRI and Tata Steel on the India-China border, having a much longer life than the conventional road.
Similarly, the National Highways Authority of India (NHAI) has also successfully used this technology in road construction on National Highway-66 (Mumbai-Goa) in collaboration with JSW Steel, under the technical guidance of CRRI.
The Minister also highlighted that the Steel Ministry is working with the Ministry of Science and Technology and the Ministry of Road Transport and Highways, Government of India, for the usage of steel slag road technology throughout the country.
