A new-age self-compacting, self-levelling concrete, Agilia – recommended by Nuvoco Vistas Corp (formerly Lafarge India Limited) – was used for constructing a state-of-the-art Oncology Radiation Chamber in Kiran Multi Specialty Hospital in Surat; making it the first-of-its-kind in Gujarat.

The scope of work involved construction of three bunkers of 256 sq m (2,754 sq ft) as per the Atomic Energy Regulatory Board (AERB) regulations. These require the density of concrete to be uniform throughout the structure, with minimum density being more than 2,400 kg/m3. It bears pointing out that AERB has non-negotiable and stringent guidelines, and does not permit commissioning of a facility unless those specifications are met.

Nuvoco’s Construction Development and Innovation Centre (CDIC) team provided method statement for placement of concrete; evaluation report of performance of different mix-designs to fulfil the requirements of the job-site, and designing of proper shuttering for better performance of Agilia. With proper planning and execution, the team was able to complete the project and hand it over to the hospital team an entire month before schedule, thereby saving considerable costs. Nuvoco supplied 800 m3 of M30 Agilia with temperature control for this project.

Agilia is an ideal solution for structures with complex configurations or requirements. In this case, Agilia was used to achieve the desired density and to minimise voids within the concrete by more than 50 per cent as compared to normal concrete. One of the challenges faced during execution was that the structure was approximately 5 m below ground level. The laying and changing of the pipeline was critical to maintain a cohesive mix and to avoid pump choking. This was done by maintaining the maximum core temperature below 70?C and a temperature gradient less than 20?C by using higher Pozzolana materials in concrete.

Frederic Guimbal, Chief of RMX and Aggregates, said,’We were sure Agilia would be the answer since it offers better packing density and cohesiveness over regular concrete. Due to its self-consolidating nature, Agilia drastically reduces voids, thereby minimising the risk of radiation leakage.’

UltraTech Cement reported record financial performance for Q4 and FY26, supported by strong volumes, higher profitability and improved cost efficiency. Consolidated net sales for Q4 FY26 rose 12 per cent year-on-year to Rs 254.67 billion, while PBIDT increased 20 per cent to Rs 56.88 billion. PAT, excluding exceptional items, grew 21 per cent to Rs 30.11 billion.

For FY26, consolidated net sales stood at Rs 873.84 billion, up 17 per cent from Rs 749.36 billion in FY25. PBIDT rose 32 per cent to Rs 175.98 billion, while PAT increased 36 per cent to Rs 83.05 billion, crossing the Rs 80 billion mark for the first time.

India grey cement volumes reached 42.41 million tonnes in Q4 FY26, up 9.3 per cent year-on-year, with capacity utilisation at 89 per cent. Full-year India grey cement volumes stood at 145 million tonnes. Energy costs declined 3 per cent, aided by a higher green power mix of 43 per cent in Q4.

The company’s domestic grey cement capacity has crossed 200 MTPA, reaching 200.1 MTPA, while global capacity stands at 205.5 MTPA. UltraTech also recommended a special dividend of Rs 2.40 billion per share value basis equivalent to Rs 240.

Towards Mega Batching

Optimised batching can drive overall efficiencies in large projects.

India’s pace of infrastructure development is pushing the construction sector to work at a significantly higher scale than previously. Tight deadlines necessitate eliminating concreting delays, especially in large and mega projects, which, in turn, imply installing the right batching plant and ensuring batching is efficient. CW explores these steps as well as the gaps in India’s batching plant market.

Choose well

Large-scale infrastructure and building projects typically involve concrete consumption exceeding 30,000-50,000 cum per annum or demand continuous, high-volume pours within compressed timelines, according to Rahul R Wadhai, DGM – Quality, Tata Projects.

Considering the daily need for concrete, “large-scale concreting involves pouring more than 1,000–2,000 cum per day while mega projects involve more than 3,000 cum per day,” says Satish R Vachhani, Advanced Concrete & Construction Consultant…

Andhra Offers Discom Licences To Private Firms Outside Power Sector

Policy allows firms over 300 MW to seek distribution licences

The Andhra Pradesh government will allow private firms that require more than 300 megawatt (MW) of power to apply for distribution licences, making the state the first to extend such licences beyond the power sector. The policy targets information technology, pharmaceuticals, steel and data centres and aims to reduce reliance on state utilities as demand rises for artificial intelligence infrastructure.

Approved applicants will be able to procure electricity directly from generators through power purchase agreements, a change officials said will create more competitive tariffs and reduce supply risk. Licence holders will use the Andhra Pradesh Transmission Company (APTRANSCO) network on payment of charges and will not need a separate distribution network initially.

Licences will be granted under the Electricity Act, 2003 framework, with the Central and State electricity regulators retaining authority over terms and approvals. The recent Electricity (Amendment) Bill, 2025 sought to lower entry barriers, enable network sharing and encourage competition, while the state commission will set floor and ceiling tariffs where multiple discoms operate.

Industry players and original equipment manufacturers welcomed the policy, saying competitive supply is vital for large data centre investments. Major projects and partnerships such as those involving Adani and Google, Brookfield and Reliance, and Meta and Sify Technologies are expected to benefit as capacity expands in the state.

Analysts noted India’s data centre capacity is forecast to reach 10 gigawatts (GW) by 2030 and cited International Energy Agency estimates that global data centre electricity consumption could approach 945 terawatt hours by the same year. A one GW data centre needs an equivalent power allocation and one point five times the water, which authorities equated to 150 billion litres (150 bn litres).

Advisers warned that distribution licences will require close regulation and monitoring to prevent misuse and to ensure tariffs and supply obligations are met. Officials said the policy aims to balance investor requirements with regulatory oversight and could serve as a model for other states.
