India: JSW Cement recorded a market share of 83% in the Indian ground granulated blast furnace slag (GGBS) market in the 2024 financial year, which ended on 31 March 2024. CNBCTV News has reported that JSW Cement sells GBFS produced from slag supplied by fellow JSW Group company JSW Steel, alongside other partners in the steel sector. JSW Steel is presently expanding its refineries in Dolvi, Maharashtra, and Vijayanagar, Karnataka.

JSW Cement’s existing customers include construction firms for the Mumbai Coastal Road, Mumbai Trans-Harbour Sea Link, Bengaluru International Airport and nuclear power plant projects. India’s total national consumption of slag in the reporting period was an estimated 6 – 6.2Mt. Ratings agency CRISIL has forecast composite annual growth of 15 – 16% until the 2029 financial year, to reach 13Mt.

India: The Samruddhi Expressway stretches 701km from Nagpur to Mumbai. This project by the Maharashtra State Road Development Corporation (MSRDC) has been focused on reducing environmental impact by the use of fly ash and blast furnace slag in its concrete.

Anil Gaikwad, managing director of the MSRDC, said "Fly ash and ground granulated blast furnace slag were also used in the concrete,” He continued “Fly ash has been used to the extent of 20% in the concrete."

The project emphasised circularity by reusing and recycling materials. Responsible sourcing of materials was a key component, ensuring vendors complied with environmental standards. Innovative water management strategies were also implemented, including the creation of farm ponds through agreements with local farmers.

India: JSW Cement has appointed Finland-based Coolbrook to install its RotoDynamic Heater electric kiln technology at the Vijayagar steel works and slag and cement grinding plant in Karnataka.

India: Finland-based Betolar introduced its AI-based service for production of reduced-CO₂ concrete using its Geoprime additive at World of Concrete India 2023 on 18 October 2023. Betolar designs recipes and provides a liquid chemical dosing system and post-production services to Geoprime users. Dow Jones Institutional News reports that Betolar has concluded strategic tie-ups in South and West India, and is ‘actively planning’ further expansion.

Managing director Abhishek Bhattacharya said "Interest in our solution is growing fast in India and we have successfully demonstrated that the twin goal of sustainability and performance can be achieved remarkably faster with Betolar’s Geoprime solution.”

India: The Border Roads Organisation (BRO) has been using steel slag as part of construction activity near its border with China. BRO Director General Lt General Rajeev Chaudhry made the comments as part of an inspection tour, according to the Press Trust of India. The BRO and other government agencies have increased activity near the border since 2020. Chaudhry said that around 300 BRO projects worth over US$950m had been completed in recent years. This included 295 road projects, bridges, tunnels and airfields. One notable achievement has been the construction of a vehicle-quality road at Demchok with an altitude of over 5750m, higher than the base camps for Mount Everest.

India: Bokaro Steel Plant has won granulated blast furnace slag (GBFS) supply contracts with ACC and UltraTech Cement. Under the contracts, Bokaro Steel Plant expects to supply 1.3Mt of GBFS from its facilities in Jharkhand for use in cement production in the state. The Pioneer newspaper has reported that the contracts will run until August 2026.

Europe/India: Finland-based Betolar has secured EU-wide and Indian patents for a new waste-based alternative concrete produced without cement and capable of storing energy. Betolar said that the material, which is already patented in Finland, is especially suited for use in renewable energy infrastructure, where it can provide a storage solution for dealing with short-term peaks. Chief commercial officer Ville Voipio said that the company will now seek to establish a partnership for commercialisation of its new alternative building material.

Betolar produces and markets the Geoprime additive used to produce cement-free concrete from supplementary cementitious materials, including ground granulated blast furnace slag (GGBFS), in regions that include India and the EU.

India: Construction is underway on a section of National Highway 66 in Maharashtra which is being built of concrete made from ground granulated blast furnace slag (GGBFS) and slag cement. India Today News has reported that the Central Road Research Institute developed the technology, in partnership with the National Institute for Transforming India Aayog and the Council of Scientific and Industrial Research.

India: The Border Roads Organisation (BRO) has used steel slag to construct a 1km section of National Highway 713 that connects Arunachal Pradesh's Kurung Kumey district to the Chinese border. The slag material was donated by Tata Steel and transported from Jamshedpur to Arunachal Pradesh by Indian Railways free of charge, according to the Press Trust of India. The project was an initiative of BRO Director General Lt Gen Rajeev Chaudhry to introduce sustainable new technologies with the help of Central Road Research Institute-Council for Scientific & Industrial Research (CRRI-CSIR) and Tata Steel.

India: Finland-based Betolar has launched its first concrete products manufactured using Geoprime on the Indian market. Geoprime is an additive designed for use in cement-free concrete production with ash and ground granulated blast furnace slag (GGBFS). The new concrete product range consists of precast blocks, paving slabs and tiles, and is currently on display at World of Concrete India in Mumbai, Maharashtra.

Betolar's India managing director Abhishek Bhattacharya said "We are happy to introduce our first products to our customers for the Indian markets. We have now moved from laboratory tests into the production phase, and can show concretely how well this solution works. It is great to hear the feedback from the concrete industry in the region to our sustainable solution. Decarbonisation of the concrete industry is a very current and important topic."
