Bangladesh: Chhatak Cement’s plant in Sunamganj remains idle despite construction completing in March 2023, with production suspended due to unresolved gas and limestone supply issues, according to the Prothom Alo newspaper. The plant project began in 2016. New details confirm that the Bangladesh government has approved subcontracting of a cross-border ropeway to import limestone from India. Local firm Komorah Limestone Mining Company (KLMC), which already supplies limestone to Chhatak Cement, is in talks regarding the role. China-based contractor for the project, Nanjing Sea-Hope Cement Engineering, has agreed ‘in principle’ to this handover as of 18 March 2025, according to Chhatak Cement managing director Abdur Rahman.

Project officials stated that, once the new plant begins operations, it will be capable of producing 1500t/day of clinker and 500t/day of cement, triple its previous capacity. Reporters conducted a site visit on 8 April 2025, observing that a jetty had been constructed on the riverbank to unload clinker from the plant for grinding elsewhere. A conveyor system has been set up to move cement bags directly from the plant to transport, and a new conveyor belt has also been installed alongside the existing belt.

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.

Iraq: Lucky Cement has expanded its clinker production at its joint venture Najmat Al-Samawah plant in Samawah with a new 1.82Mt/yr line, with the kiln successfully firing on 13 May 2025, according to a company announcement published on 14 May 2025. Lucky Cement said that it is also building a 0.65Mt/yr cement grinding plant at the site, due for commissioning in early 2026.

The producer said that the new capacity will enable it to supply more cement to the local market, with surplus marketed and sold domestically. These additions will bring Lucky Cement’s total consolidated production capacity to 21.48Mt/yr, across operations in Pakistan, Iraq and the Democratic Republic of Congo.

Bolivia: Empresa Pública de Cementos Bolivia (ECEBOL) will begin exporting 12,500t/month of clinker to Mexico from June or July 2025, following the finalisation of a supply contract in late May 2025, according to Ahora El Pueblo newspaper.

Technical manager Aldo Olivera said that the deal will be Ecebol’s first clinker export contract, and that negotiations have been underway for several months. Oliviera said that the company hoped to achieve between US$7m - 8m over the course of the contract.

India: Wonder Cement’s managing director Kiran Patil led the inauguration of Line 5 at the Nimbahera plant in Rajasthan on 7 May 2025, according to a social media post by the producer. The project increased the producer’s clinker capacity by 2.8Mt/yr to 13.35Mt/yr and cement capacity by 2.5Mt/yr to 21.5Mt/yr. The company partnered with APBCO on the expansion, which also includes a 12MW waste heat recovery system to increase energy efficiency.

Kenya: Kenya’s cement clinker imports have dropped by 93% year-on-year to 10,340t in 2024 from 148,000t in 2023, according to the government’s 2025 Economic Survey. The value of imported clinker fell to US$27,500 from US$409,000 in 2023 and US$3.2bn in 2020. Import volumes had already fallen by 77% in 2023, from 656Mt in 2022.

Cement production declined by 7% from 9.6Mt to 8.9Mt in 2024, while consumption also fell by 7% to 8.5Mt. Construction sector growth contracted by 0.7% in 2024, down from 3% in 2023.

Spain: Cement consumption in Andalusia rose by 13% year-on-year in the first quarter of 2025 to 763,000t, according to the Andalusian Cement Manufacturers Association (AFCA).

In March 2025, consumption reached 254,000t, up by 12% year-on-year. However, clinker and cement exports fell by 9% to 97,600t during the same period.

AFCA president Ricardo de Pablos said “The first quarter of the year reflects a positive trend in cement consumption and, therefore, in construction sector activity.”

De Pablos added that building permits for new homes grew by 31% in 2024, with 31,296 homes authorised for construction throughout 2025, but warned that no investment growth is expected in 2025.

Uganda: Lands, Housing and Urban Development minister Judith Nabakooba said that the government and the Naita-A-Tepeth Communal Land Association have finalised a lease agreement to enable Tororo Cement to build Uganda’s first clinker plant in Katikekile, Moroto District. Nabakooba said that the project began in 2023, and will reduce clinker imports and conserve foreign exchange.

According to a social media post by the ministry, the agreement includes the sale of 202 hectares to Tororo Cement for the plant site, the lease of 3824 acres to the Uganda Investment Authority and the titling of institutional land for local public use.

US: France-based Fives Group has launched new subsidiary Fives FCB USA in Alabama to supply the North American market with low clinker blended cement and supplementary cementitious material production equipment and services. Products being promoted include the FCB Horomill, the FCB TSV Classifier and the FCB Rhodax. The unit will share premises with Fives’ North American Construction Services company.

Deputy general manager Alain Cordonnier said “The opening of our subsidiary in the US marks a significant milestone for Fives FCB. We are excited to bring our innovative technologies and expertise to the US market, and we look forward to building strong partnerships with local industry leaders.”

Anhui Conch Cement held an event in Wuhu, China, this week showcasing its new artificial intelligence (AI) model for the cement sector. The cement company and Huawei started the project in April 2024 with the support of the China Building Materials Federation. The companies say they have now identified over 200 “promising AI application scenarios across 15 categories” across the entire production process from quarrying to packaging and logistics. Conch has set up an AI training centre using the Huawei Cloud Stack product. It is using Huawei’s Pangu prediction, computer vision (CV) and natural language processing (NLP) models to create an AI operating system that integrates central training, edge inference, cloud-edge synergy, continuous learning and ongoing optimisation.

Thankfully Huawei gave some examples of what this actually meant for operators in the real world. The model is able to give real-time recommendations of key quality features enabling the prediction of three-day and 28-day clinker strength. The predicted strength values closely match test results, with deviations within 1MPa and an accuracy rate exceeding 85%. Other benefits include reducing kiln fuel consumption by 1%, monitoring and managing various components and machines along the production line, staff safety gains and creating a ‘smart digital assistant’ that can answer technical questions from employees.

Little of this seems particularly novel, so far, compared to what other companies are already doing in this field. For example, ABB said in early 2022 that it was using machine learning to predict 28-day strength on the day of sampling and in 2023 that it was doing it using production data provided every two - three hours. Another example is the work that Inform does using AI-based software to support logistics for heavy building materials. Plenty of other western-based companies also offer production optimisation and/or predictive maintenance products.

Conch’s use of an NLP model to create a knowledge base assistant does seem new for the cement sector. Although how specific the software running it might be to one business or industrial area remains to be seen. One could easily imagine this kind of product being sold to lots of different kinds of industries in the manner of current enterprise style software. Along these lines though, Juan Beltrán, digital manager of global sales excellence at Holcim, told McKinsey in an interview about Holcim’s pilot project in Spain testing an AI-enabled copilot customer-ordering assistant via WhatsApp.

Recent events in AI for the cement sector include ABB’s agreement to work with UK-based Carbon Re in late 2024. This collaboration was intended to combine ABB's expertise in automation and process control with Carbon Re's AI and machine learning technologies. It followed a pilot at a cement plant in the Czech Republic. On the producer side, Holcim said in mid-2024 that it was preparing to expand the use of AI-based software to 100 production plants by 2028. It noted that it had installed the system at 45 plants so far at the time of this announcement and that it was using a predictive maintenance solution from software supplier C3 AI. Titan Cement said that it had invested in Spain-based AI software supplier Optimitive in February 2025. Then, Cemex announced this week that it too had invested in Optimitive, via its corporate venture capital arm Cemex Ventures. Molins has also worked with Optimitive.

What isn't being disclosed much are the examples of the mistakes of introducing AI into cement production. These are valuable learning opportunities for any company implementing this kind of software. However, the developers and cement producers are extremely unlikely to admit anything publicly. Global Cement Weekly has heard off-the-record information previously about AI projects at cement plants that have gone wrong but we can’t reveal it either. To his credit though Beltrán mentions an incident, in his interview with McKinsey, where the WhatsApp ordering assistant was tricked during testing into almost placing an order for a truck of gazpacho soup!

We’re still watching how AI is being deployed in heavy industries such as cement. The announcement by Conch is exactly the kind of thing its peers are doing around the world. So far what they’ve done is impressive but not unique. Yet, China’s large but shrinking cement sector and its determination to develop its own AI-based software sector may start to deliver more cutting-edge advances in the future. Companies elsewhere are also pressing ahead to find out how AI products will deliver efficiency gains.
