India’s largest aluminium manufacturer, Vedanta Aluminium, has delivered its first rake of 4,000 tonnes of fly-ash from its Jharsuguda facility to one of Holcim India’s ACC Cement Chaibasa Cement Works for the manufacturing of low-carbon cement.

This programme is one of Vedanta Jharsuguda’s waste-to-wealth imperatives, and it guarantees that an industrial by-product like fly-ash is used profitably in circular economy channels.

Fly-ash is a by-product of coal-fired thermal power generation and is used to meet the energy needs of Vedanta’s Jharsuguda aluminium smelters.

Fly-intrinsic ash’s properties may be used to improve product quality while also conserving energy, water, and other critical resources and lowering the industry’s carbon impact.

It offers considerable cost and energy savings as a large-scale industrial waste. Every tonne of fly-ash used in cement production may help save 700 kg to 800 kg of carbon emissions, 4.2 million kilojoules of energy, and 341 litres of water.

To identify new methods to use this industrial byproduct, the company holds workshops around the country with international specialists to raise awareness about the advantages of employing fly-ash in a cement building.

Vedanta has been supplying fly-ash to several cement firms in the Jharsuguda area. Vedanta Jharsuguda delivered 190,000 tonnes of fly-ash to local cement factories and 60,000 tonnes to local brick-making Micro, Small & Medium Enterprises (MSMEs) in fiscal year (FY) 2022.

In addition, the firm has formed a long-term relationship with India’s National Highways Authority (NHAI) to develop greener roads using fly-ash. The company has achieved the greatest ever fly-ash usage this year as a result of its consistent efforts in this regard.

The decision to ship fly ash via rail is to the company’s ambition of meeting its environmental sustainability goals, with the ultimate goal of becoming carbon neutral by 2050.

Niraj Kumar Bansal, Vice President and Head-India Raw Materials & Inward Logistics ? Supply Chain; ACC & Ambuja Cements Ltd (Holcim-India), told the media that Holcim India’s (ACC & Ambuja) partnership with Vedanta for fly ash evacuation is in line with their organisation’s endeavours to promote a circular economy, bringing in sustainable growth.

He said that the cement industry uses fly-ash for blending purposes, and it offers several advantages in terms of cost, quality, and workability, as well as increased strength.

Bansal said that the cement industry should be keen on the prospect of using this industrial byproduct to its benefit.

The need of present time is stronger buildings, industrial or common utility buildings, such as Malls, Railway stations, hospitals, offices, bridges etc. For this, there is need of long durable, tough and stable concrete, which could stand under normal and seismic conditions. Tough railway bridges are required for bullet trains to pass without any damage. Railway tunnels, sea-links, coastal roads, bridges and multistorey buildings, are the need of the hour. The question comes, is the normal cement called OPC is sufficient to take care of such requirements or better combination of cements and sand mixtures is required?

Introduction

A good stable building structure can be made with a good quality of cement+sand+water system. Its quality can be enhanced by keeping the density of admixture higher (varies from 30 in normal buildings to bridges etc to 80). Further enhancement in the properties of various cements admixtures is made by adding several additives which give additional strength, waterproofing, flexibility etc. These are called construction chemicals…

The National Council for Cement and Building Materials (NCB) has signed a memorandum of understanding with a leading cement manufacturer to strengthen skill development and capacity building in the construction sector. The agreement was formalised at NCB premises in Ballabgarh and was signed by the Director General of NCB, Dr L. P. Singh, and the head of technical services at UltraTech Cement Limited, Er Rahul Goel. The collaboration seeks to bring institutional resources and industry expertise into a structured national training effort.

The partnership will deliver structured training and certification programmes across the country aimed at enhancing the capabilities of civil engineers, ready?mix concrete (RMC) professionals, contractors, construction workers and masons. Programme curricula will cover material quality testing, concrete mix proportioning, durability assessment and sustainable construction practices to support improved construction outcomes. Emphasis is to be placed on standardised assessment and certification to raise practice levels across diverse construction roles.

Practical learning elements will include workshops, site demonstrations, technical seminars and exposure visits to plants and RMC facilities to strengthen applied skills and on?site decision making. The Director General indicated confidence that a large number of professionals and workers would be trained over the next three to five years under the initiative. The partnership is designed to complement flagship government schemes such as the Skill India Mission and to align training outputs with national infrastructure priorities.

By combining the council’s technical mandate with industry experience, the initiative aims to develop a more skilled and quality?conscious workforce capable of meeting rising demand in infrastructure and housing. NCB will continue to coordinate programme delivery and quality assurance while industry partners provide practical exposure and technical inputs. The collaboration is expected to support long?term capacity building and more sustainable construction practices nationwide.

JSW Cement has strengthened its national presence by commencing production at its greenfield integrated cement plant in Nagaur, Rajasthan, marking its entry into the north Indian market.

With this commissioning, the company’s installed grinding capacity has increased to 24.1 MTPA, while total clinker capacity, including its joint venture operations, stands at 9.74 MTPA.

The Nagaur facility comprises a 3.30 MTPA clinkerisation unit and a 2.50 MTPA cement grinding unit, with an additional 1.00 MTPA grinding capacity currently under development. Strategically located, the plant is positioned to serve high-growth markets across Rajasthan, Haryana, Punjab and the NCR.

The project has been funded through a mix of equity and long-term debt, with Rs 800 crore allocated from IPO proceeds towards part-financing the unit.

Parth Jindal, Managing Director, JSW Cement, stated that the commissioning marks a key milestone in the company’s ambition to become a pan-India player. He added that the project was completed within 21 months and positions the company to achieve its targeted capacity of 41.85 MTPA by FY29.
