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.

Nilesh Narwekar, CEO, JSW Cement, highlighted that the expansion aligns with the company’s strategy to tap into rapidly growing northern markets driven by infrastructure development. He noted that the company remains focused on delivering high-quality, eco-friendly cement solutions while progressing towards its long-term capacity goal of 60 MTPA.

The Nagaur plant has been designed with sustainability features, including co-processing of alternative fuels and a 7 km overland belt conveyor for limestone transport to reduce road emissions. The facility will also incorporate a 16 MW Waste Heat Recovery System to improve energy efficiency and lower its carbon footprint.

JSW Cement, part of the JSW Group, operates across the building materials value chain and currently has eight plants across India, along with a clinker unit in the UAE through its joint venture.

Cement Prices Likely To Rise As Petcoke Costs Increase

Nuvama warns input costs may lift prices by early April 2026

A report by Nuvama Wealth Management said cement prices in India could rise by the end of March or early April 2026 as producers face higher input costs linked to crude oil. The report identified rising petroleum coke and packaging material costs as principal drivers of upward pressure on production expenses. Petroleum coke, a fuel used in cement manufacturing, rose by about 13 per tonne (t) in US dollar terms in February 2026, a change that could be passed on to buyers. Producers may adjust prices later in the quarter to protect margins.

Cement demand remained stable during February and March 2026, supported by ongoing construction and infrastructure activity, and earlier price increases on non-trade sales were largely reversed by the end of February. Retail prices remained broadly steady through March in most regions. The persistence of demand may allow firms to manage price adjustments rather than apply uniform increases. Market responses will vary by region and logistical cost pressures.

Nuvama said that stock performance of cement companies will likely be influenced by the path of cement prices and petroleum coke costs in the coming weeks. Rising input costs including crude linked fuels and packaging may squeeze profit margins and prompt firms to monitor pricing and demand closely. The balance between input inflation and end demand will determine whether companies absorb costs or transfer them to customers. Analysts will watch forthcoming quarterly results for evidence of margin pressure or successful cost pass through.

Government capital expenditure showed moderation, with overall capex declining 24 per cent year-on-year to around Rs 2 trillion (Rs 2 tn) in January 2026 and cumulative capex from April 2025 to January 2026 at about Rs 20 trillion (Rs 20 tn), up eight per cent year-on-year. The report noted that real estate launches fell 44 per cent year-on-year in January 2026, and overall healthy demand could still be offset by rising crude linked input costs that may push cement prices higher by late March or early April 2026.
