India: Ambuja Cements subsidiary ACC has commissioned a 1.5Mt/yr brownfield grinding unit at its Sindri plant in Jharkhand. The project takes the total installed cement production capacity across Ambuja and ACC to 104.45Mt/yr.

Mozambique: Moçambique Dugongo Cimentos will invest US$35m in a third cement plant in Ancuabe, Cabo Delgado province, according to local press. The plant is presumed to be a grinding facility due to the value of the investment. Project coordinator Anselmo Amurane said that the plant’s design is under development, with community consultations completed and environmental assessments pending. The start date for construction was not disclosed.

Amurane said “We hope to contribute to increasing the overall cement supply and production capacity,” adding that the project would employ 900 construction workers and 135 operational workers.

Moçambique Dugongo Cimentos is a joint venture between Mozambique-based SPI Gestão and China-based West International Holding. The plant operates two plants in the cities of Maputo and Nacala.

Brazil: Votorantim Cimentos has received and begun installing a new cement mill at its Salto de Pirapora plant near São Paulo as part of its US$878m national expansion programme.

The 210t mill took six months to arrive from China via ship, and was then transported by a truck convoy from the Port of Santos to the plant. The mill will increase the plant’s capacity by 1Mt/yr. The unit is part of the Salto-Santa Helena complex, which will see its capacity grow by 20% when the expansion completes in the second half of 2025. Construction began in the first half of 2024.

General manager Rafael Frederico said “We are celebrating a new phase in the expansion project of the Salto de Pirapora plant with the arrival of the mill and all the equipment for assembling the new mill. The operation to transport the equipment from China to our unit was complex and executed with great operational excellence by our multidisciplinary teams and partners.”

Demand for heavy building materials in the UK dropped in the first quarter of 2025, with ready-mix concrete sales reaching a new 60-year low.¹ In an update last week, the UK’s Mineral Products Association (MPA) attributed the decline to existing economic headwinds, compounded by global trade disruptions, reduced investor confidence and renewed inflationary pressures.

Major infrastructure projects – including the HS2 high-speed railway in the English Midlands, the Hinkley Point C nuclear power plant in Somerset and the Sizewell C nuclear power plant in Suffolk – failed to offset delays and cancellations by cash-strapped local councils to roadwork projects. Residential construction, meanwhile, is ‘slowly but steadily’ recovering from historical lows, amid continuing high mortgage rates since late 2024.

The most interesting part of the MPA’s market appraisal was its warning of ‘new risks emerging in the global economy.’ These concern the new tariffs raised by the US against its import partners. The possible consequences, the MPA says, imperil the UK’s supply chains, construction sector and growth.

Of particular immediacy is the threat of imports into the UK from countries that previously focussed on the US market. The MPA said that the industry ‘cannot compete’ against increased low-cost, CO₂-intensive imports. It named Türkiye, which sends around 6.9Mt/yr of cement and clinker to the US, as a key threat. Türkiye became subject to the blanket 10% ‘baseline’ tariff on 2 April 2025.

The MPA probably didn’t have a particular company in mind when it said this. However, it bears noting that Turkish interests gained a share of UK cement capacity in October 2024, when Çimsa acquired 95% of Northern Ireland-based Mannok. Besides the Derrylin cement plant (situated on the border between Fermanagh, UK, and Cavan, Ireland), Mannok operates the Rochester cement storage and distribution facility in Kent, 50km from London. The facility currently supplies cement from Derrylin to Southern England and the Midlands. It could easily serve as a base of operations for processing and distributing imported cement and clinker from further afield.

Meanwhile in South West England, Portugal-based Cimpor is building a €20 – 25m cement import terminal in the Port of Bristol. The company is subject to 20% tariffs on shipments to the US from its home country. Its parent company, Taiwan Cement Corporation, is subject to 32% US tariffs from Taiwan.

But the plot thickens… On 8 May 2025, the UK became the first country to conclude a trade agreement with the US after the erection of the new tariff regime, under which the US$73bn/yr-worth of British goods sold in the US became subject to a 10% tariff.² The latest agreement brought partial relief for an allied sector of UK cement: steel. 180,000t flowed into the US from the UK in 2024.³ In 2024, the UK exported 7120t of cement and clinker to the US, up by a factor of 10 decade-on-decade from just 714t in 2014, all of it into two US customs districts, Philadelphia and New York City.⁴

In what may be one of the first true ‘Brexit benefits,’ UK cement exporters now ‘enjoy’ a US tariff rate half that of their EU competitors, notably those in Greece. Like the UK’s more modest volumes, Greece’s 1.82Mt/yr-worth of cement and clinker exports stateside also enter via the US’ eastern seaports, at New York City, Tampa and Norfolk. Given the overlaps in ownership between the Greek and UK cement sectors, it is conceivable that optimisation of cement export flows across Europe may already be under discussion.

On 6 May 2025, the UK and Indian governments announced a trade deal that will lift customs duties on almost all current Indian exports to the UK. UK MPs are still seeking clarifications as to whether this will include industrial products that might be dumped.⁵ Theoretically, the threat from an oversupplied and fast-growing cement industry like India’s could be existential to the UK cement industry.

As the UK invests heavily in its future, including with the HyNet Consortium, imports pose a major threat. Given enough time, the UK could develop a leading position in the decarbonisation space. Will it have enough time? Existential threats certainly add a sense of jeopardy.

India: UltraTech Cement has increased its production capacity by 1.4Mt/yr through debottlenecking and ‘efficiency improvements’ at multiple sites across India.

It added 0.6Mt/yr of grinding capacity at Nagpur in Maharashtra and 0.8Mt/yr across Panipat and Jhajjar in Haryana. The company’s total domestic grey cement capacity now stands at 184.8Mt/yr, while its global capacity has reached 190.2Mt/yr.

India: Nuvoco Vistas will build a 2Mt/yr grinding unit in Kutch as part of its plan to refurbish and put into operation the recently acquired assets of Vadraj Cement. The project adds US$35m to the US$141m originally allocated to restart Vadraj’s cement assets in Kutch and Surat, bringing the total planned investment to US$177m, phased over 2025 to 2027. Nuvoco aims to commission the grinding unit and start up the existing Vadraj assets by December 2027. These include a 3.5Mt/yr clinker unit in Kutch, a 6Mt/yr grinding unit in Surat and limestone reserves.

Nuvoco’s total production capacity will increase to around 31Mt/yr. The company currently sells 1Mt/yr of cement in Gujarat from its facilities in Rajasthan, but post-commissioning, the Kutch and Surat sites will serve Gujarat and northern Maharashtra and release Rajasthan capacity for northern markets.

India: Shree Cement has commissioned its new grinding unit in Etah, Uttar Pradesh, with an investment of US$917m, funded through internal accruals. The plant’s location near railway lines allows for efficient transport of raw materials from Rajasthan, and the unit will distribute cement via roadways and a new highway-access road. It features ‘zero-waste’ operations, air-cooled screw compressors to reduce water usage and advanced filtration systems.

The plant will consume 5000t/day of fly ash from the adjacent Jawaharpur Thermal Power Plant. A solar power installation is planned within two to three years.

India: Dalmia Cement (Bharat), a material subsidiary of Dalmia Bharat, has commenced commercial production at its cement grinding unit at Rohtas Cement Works in Rohtas district, Bihar, increasing capacity by 0.5Mt/yr to 1.6Mt/yr.

With this rise in cement capacity, the group’s total cement production capacity now stands at 49.5Mt/yr.

India: The Ramco Cements has increased the capacity of its Kalavatala plant in Andhra Pradesh from 2Mt/yr to 2.4Mt/yr by de-bottlenecking and optimising the cement mill. The producer's total cement grinding capacity now stands at 24.4Mt/yr.

Australia: Boral will receive US$15.4m in government funding for a kiln feed optimisation project at its Berrima Cement Works, with CO₂ emissions expected to reduce by up to 100,000t/yr, based on predicted production rates. The Powering the Regions grant will support the producer’s installation of a new specialised grinding circuit and supporting infrastructure, which will raise the use of alternative raw materials in kiln feed to 23% from 9%, lowering the amount of limestone used.

Boral will use steel manufacturing by-products and industrial waste, including granulated blast furnace slag, steel slag, cement fibre board, fly ash and recycled fine concrete aggregates. The project will be operational in 2028.

The head of innovation and sustainability at Boral, Ali Nezhad, said “In terms of the resulting emissions intensity of the manufactured clinker, the project will result in up to 11% reduction in clinker emission intensity, 9% attributable to a reduction in calcination emissions and 2% attributable to thermal efficiency gains.”
