When Volumes Matter

Published

The fourth quarter of the last financial year was a washout for the cement sector as prices dipped across the country. From a drop of Rs.5 per bag in central India to a drastic cut of Rs.10 per bag in Gujarat, the flat trend of the last few months can be attributed to unseasonal rains and low labour availability affecting construction activities. Volume push, fall in demand and increased discount offerings are other factors that have affected attempts of price hikes. But fast recovery is expected in the June quarter as demand picks up amid seasonal recovery.

Another reason for the cement sector to recover on the price front is the upcoming elections. With elections scheduled in 2024, the government is accelerating all of its housing and infrastructure initiatives, thereby spurring the demand for cement. Cement companies are definitely bullish about growth and the Indian cement industry is likely to witness a fresh capacity increase of 145 MT-155 MT amounting to a capex of Rs.1.2 lakh crore by FY27. A report by CRISIL confirms that demand for cement will remain buoyed at a CAGR of 6-7 per cent over the forecast period. The addition of 145 MT-155 MT to the already existing capacity of 570 MT will further consolidate India’s position as the second largest cement producer in the world.

Cement is an important component of revenue for the state governments and this point has been underscored by the recent impasse in Himachal Pradesh where the Ambuja and ACC plants had been shut down for over two months over the disagreement over freight charged by the 6,500 truckers. The state government was losing Rs.60 cr to Rs.80 cr per day in electricity, VAT and GST. A GST cut from 28 per cent to 18 per cent would reduce GST revenues by Rs.13,000 cr annually. However, if this reduction in price is passed on to the consumers, a higher demand could reduce the reduction in revenue. Finally, the impasse was resolved with the intervention of Himachal Pradesh Chief Minister Sukhvinder Singh Sukhu. Himachal Pradesh truckers, agreed to a lower freight rate after the company assured them of additional volumes from neighbouring states.

Another trend that is emerging with regards to adding fresh capacity is the logistics-oriented approach. Many cement companies are preferring to install their new grinding units near the distribution centres for freight cost rationalisation. This will also boost the attempts to decarbonise cement. Further, initiatives such as the launch of LNG trucks by Dalmia Cement (Bharat) for transportation of raw materials and bagged cement is helping build a green supply chain for cement. Decarbonisation is taking place in every step of the supply chain, and India is definitely a trailblazer in green initiatives in the cement sector.

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.
