JSW is a prominent cement producer. The company is also adopting various means to become environmentally friendly, and is now marketing slag as a product, says Lopamudra Sengupta – VP, Technical, JSW Cement.

Slag is a byproduct from steel plants, which is obtained from blast furnaces, during the extraction of iron from iron ore. The process of granulating of the slag involves cooling of molten slag through high-pressure water jets. This rapidly quenches the slag and forms granular particles. The resulting granular material comprises around 95 per cent non-crystalline calcium-alumino silicates. The granulated slag is further processed by drying and then grinding in a vertical roller mill or rotating ball mill to a very fine powder, which is called Ground Granulated Blast Furnace Slag or GGBS. The benefits, application and performance of GGBS are same as that of PSC. In case of PSC, predetermined dosage of GGBS is added, whereas GGBS separately combined with OPC, offers the flexibility of using any particular dosage depending on the choice of the user.

Some of the major advantages of GGBS concrete, as compared to pure OPC concrete or fly ash based concrete are given below:

Reduced thermal cracks due to lower heat of hydration;
Reduced shrinkage cracks;
Improved workability and smooth finish;
Improved cohesion;
Better resistance against chemicals such as chlorides, sulphates and carbon dioxide;
Higher long-term strength;
Improved durability;

JSW GGBS also meets the requirements of IS: 12089-1989. It is also an eco-friendly green product. JSW GGBS can be used as a partial replacement to OPC cement in concrete production at RMC batching plants and site batching plants.

JSW Portland Slag Cement (PSC)
JSW PSC is a blended cement, wherein some portion of OPC is replaced with GGBFS, to make the structures long lasting and durable. GGBFS present in PSC helps in secondary hydration, producing more C-S-H gel in the system for improved performance of concrete.

PSC can be used in all types of civil engineering works GCo in both structural and non-structural applications. In fact, it has got a wide spectrum of applications as compared to OPC. OPC is not suitable for works such as mass concrete, industrial structures, marine structures, effluent and sewage treatment plants. PSC is an ideal cement in these works, thus making it a perfect all-purpose cement.

PSC is also a sustainable material. As production of PSC ensures the conservation of natural resource (limestone), generates savings in energy in the production process and limits the emission of carbon dioxide, it is regarded as an eco-friendly cement or green cement.

The properties of PSC have been specified by BIS in IS: 455-2015. CII – IGBC has certified JSW PSC as a green product.

The way ahead
The usage of blended products (PSC & GGBS) ensures a pollution-free environment, and ensures no adverse impacts on the health of nearby communities. Utilisation of slag and other by-products minimises the burden on landfills and reduces virgin material usage, fossil fuel usage, and greenhouse emission reductions. Hence, it has a direct contribution to reversing the effects of global warming and climate change. The products of granulated slag are regarded as environment friendly and durable materials that can protect the environment by limiting the exploitation of natural resources and reducing the amount of energy consumed in the mining of natural resources, helping in sustainable development.

14th RAHSTA (Roads and Highways Sustainable Technologies & Advancement) Expo – India’s biggest road exhibition – will be held as a part 10th India Construction Festival 2024 at Jio Convention Centre, Mumbai, from October 9-10, 2024.

April 10, 2024, Delhi

“The RAHSTA expo will offer extensive information about the latest technology and methods for constructing high-quality roads. Currently, the challenge facing the roads industry is to uphold road quality and execute projects efficiently. RAHSTA will provide opportunities for everyone to learn about the latest worldwide technologies and equipment available, undoubtedly offering valuable insights to those involved in the roads sector,” said Vinod Kumar Yadav, Director – Transport, NCC, and former Chairman, Railway Board, while speaking during the launch of a road show – 14th RAHSTA Expo, which will be held from October 9-10, 2024, at Jio Convention Centre, Mumbai.

RAHSTA, which stands for Roads and Highways Sustainable Technologies & Advancement, is a dedicated event to the world of road construction equipment, technology, and sustainability.

“The Ministry of Road Transport & Highways has constructed 12,349 km of national highways in 2023-24 – the second highest achievement! In 2020-21 a record 13,327 kms had been constructed, the highest so far. The experience of a well-constructed road is no accident but a badly constructed one can cause many,” stated Pratap Padode, Founder, FIRST Construction Council, a pioneering infrastructure-driven council focused on advancing India’s infrastructure development.

Also speaking at the launch, former Managing Director of Ashok Leyland & JCB, Vipin Sondhi, also Chairman of RAHSTA Expo Committee underscored the need for specialised platforms like RAHSTA Expo for the burgeoning road construction industry.

Ashish Kumar Singh, CGM – Finance, National Highway Authority of India; RK Pandey, former NHAI member and Member of RAHSTA Expo Committee; SK Nirmal, Secretary General, Indian Roads Congress and Member of RAHSTA Expo Committee; Prof Satish Pandey, Principal Scientist, CSIR-Central Road Research Institute, Ministry of Science and Technology; Ankit Jain, CFO, Cube Highways Growth Advisors, Vijay Agrawal, Executive Director, Equirus Capital; and Subodh Dixit, Former Executive Director, Shapoorji Pallonji, participated in a round table discussion on the new BOT proposals.

The launch function at PHD Chamber for RAHSTA Expo was attended by who’s who of the infrastructure industry such Lt Gen Harpal Singh, President, International Road Federation and former Engineer-in-Chief, Indian Army; Akhilesh Srivastava, Road Safety Ambassador, International Road Federation; Sandeep Singh, Managing Director, Tata Hitachi Construction Machinery; Rajesh Menon, Director General, Society of Indian Automobile Manufacturers; Raman Kapil, President, Tata Projects; Anand Sundaresan, Director, Ammann India; Dheeraj Panda, Managing Director, Ammann India; Rajan Aiyer, Managing Director, Trimble; Satin Sachdeva, Founder & Secretary General, Construction Equipment Rental Association; Dr Swamy, Chairman, The Institution of Civil Engineers and Dr Ranjeet Mehta, Executive Director of PHDCCI, among others.

Organised by the FIRST Construction Council, the RAHSTA Expo 2024, which will be held as part of 10th India Construction Festival, will bring together industry leaders, innovators, and stakeholders for two days of exploration, collaboration, and transformation.

Besides RAHSTA Expo 2024, the India Construction Festival 2024 will include the following:

Exhibitors can use RAHSTA Expo 2024 to showcase their construction machinery, building material machines, mining machines, and construction vehicles to a targeted audience of industry professionals. RAHSTA Expo will be an ideal platform to connect with key decision-makers, generate leads, and grow business in this rapidly expanding market.
