It’s been a sobering week for the cement sector in South Korea with the release of sales data for the first half of 2025.

Data from the Korea Cement Association (KCA) shows that local shipments of cement fell by 17% year-on-year to 18.8Mt in the first half of the year. The last time half-year output was reported to be below 20Mt was in 1992. The association noted that a ‘severe’ construction recession had continued from 2024. An uptick in demand for building materials is anticipated in the second half of 2025 due to postponed construction work but it is expected to be limited by a forthcoming government budget. The association said that output for the whole of 2025 is forecast to be “significantly below 40Mt unless effective construction stimulus measures are available.”

20Mt of cement output marks a dividing line in the South Korea-based market in recent decades. Previous economic low points over the last 30 years include the Asian Financial Crisis in the late 1990s and the 2008 financial crash triggered by the subprime market in the US. However, on neither occasion did half-year cement output in South Korea fall below 20Mt. The current situation is likely to be reflected in the financial results of the local manufacturers, when they are released later in August 2025, following poor first-quarter figures.

The general construction sector is facing a tough time, with construction companies facing a liquidity crunch as lending rules have been tightened. At the same time prices and labour costs are both reportedly up by 30% in the past three years. One reaction to this in Autumn 2024 was plans suggested by construction companies to import cement from China. This gained some support from the government, which said it was looking at ways to reduce costs, but then faced opposition in the National Assembly. It is unclear what has happened since then, although KCA figures show that imports of cement grew by 40% year-on-year to 384,000t in the second half of 2024.

The cement producers have reacted by shutting down production lines in some cases. In April 2025 local press reported that eight of the country’s 35 production lines had been shut down. Hanil Cement’s Danyang plant had reportedly suspended two of its six production lines. One additional kiln at Asia Cement’s Jecheon plant was preparing to be closed at this time, with the manager citing the difficulty of coping with a 70% capacity utilisation rate. This would have brought the site’s number of active lines down to two of four. Another unmentioned kiln also reportedly preparing to suspend operations would bring the total of inactive kilns up to 10.

As might be expected in this kind of business environment, mergers and acquisitions activity has started. Hanil Cement announced in mid-July 2025 that it was preparing to buy its subsidiary Hanil Hyundai Cement. The transaction is expected to cut costs of the newly combined company and yield other synergy effects.

With its high cement consumption per capita, the cement market in South Korea remains atypical compared to peer economies in East Asia and Europe. Consumption dropped after a peak in the 1990s but it remained high by international standards. Hence the outcry about a half-year cement output bigger than most European countries can manage in a year. The IMF predicts a gross domestic product (GDP) growth rate of 0.8% in 2025 in South Korea, with a faster pickup of 1.8% in 2026. Construction levels are expected to remain sluggish into autumn and start recovering in 2026. General market trends in developed countries suggest that cement consumption will fall further in South Korea in coming decades, especially as sustainability trends embed. Cement sales in Japan, for example, have gradually been dwindling since the late 1990s. One question here is whether the cement market in South Korea can continue to hold its high level of consumption per capita. It remains to be seen.

Tanzania: Elsawy Ahmed has resigned as the manager of Twiga Cement’s Wazo Hill plant. He had been in post at the subsidiary of Heidelberg Materials since 2017. He is now working as a technical consultant.

Elsawy started his career as a Quality Control Supervisor for Assiut Cement in Egypt. He later worked for Cemex Egypt and became a plant manager for Cemex in Bangladesh in the early 2000s. He joined Italcementi in 2006 becoming Maintenance & Project Manager for subsidiary Suez Cement in the mid-2010s. Elsawy holds a degree in chemistry from Assiut University.

Ivory Coast: Dangote Cement has announced the imminent commissioning of its 3Mt/yr grinding plant in Ivory Coast, which it says will take place in the third quarter of 2025. The company says that the investment is part of its drive to enhance its regional presence in West Africa. The company’s CEO Arvin Pathak noted that the plant will streamline and provide flexibility to Dangote’s exports in West Africa, which grew by 18.2% in the first half of 2025.

Dangote Cement is Africa’s largest cement producer, with a capacity of 48.6Mt/yr. It already operates in more than 10 African markets, including Tanzania, South Africa, Ethiopia, Cameroon, the Republic of Congo and Ghana.

Canada: Ash Grove, part of CRH, and Carbon Upcycling Technologies have broken ground on a carbon capture and utilisation unit at the Mississauga cement plant in Ontario. The project will use Carbon Upcycling's technology to sequester CO₂ from the cement kiln and use it to turn industrial byproducts into supplementary cementitious materials (SCM). Once operational in 2026, the facility will have the capacity to produce up to 30,000t/yr of SCMs.

"Carbon 1 Mississauga is a milestone in our journey to build world-leading, domestic supply chains in North America. It will stand as a testament to the shared commitment of our team, our partners at CRH and Ash Grove, and the local community who share our vision for a resilient, clean tomorrow,” said Apoorv Sinha, CEO of Carbon Upcycling.

The Carbon 1 Mississauga project is being delivered through a multi-stakeholder collaboration. CRH Ventures, the venture capital unit of CRH, has invested in Carbon Upcycling and is playing a role in scaling the company's technology. The project has been awarded around US$7m in federal government funding from the Next Generation Manufacturing's Sustainable Manufacturing Program, the Environment and Climate Change Canada's Low-Carbon Economy Fund and is receiving advisory services and funding from the National Research Council of Canada Industrial Research Assistance Program.

This week Aliko Dangote retired as the chair of Dangote Cement. It’s a big deal, as Dangote founded parent company Dangote Industries in 1981 as an importer of bagged cement and other commodities such as rice, sugar, flour and salt. Over 40 years later Dangote Cement is the biggest cement company in Africa with a reported capacity of 52Mt/yr, operations in at least 10 countries and annual revenues of US$2.3bn. Dangote personally has also become Africa’s richest inhabitant along the way. It’s an extraordinary achievement.

As CEO Arvind Pathak, said in the company’s half-year report, “We celebrate our president, Alhaji Aliko Dangote, who now steps down from the board, for his pivotal and transformative role in shaping the company’s growth, success, and lasting legacy. His visionary leadership, entrepreneurial spirit, and unwavering commitment laid the very foundation of our journey. Under his guidance, the company achieved remarkable milestones, expanded its footprint, and set new standards of excellence across the industry.” Dangote is aged 68 years and his successor as chair of Dangote Cement, Emmanuel Ikazoboh, is aged 76 years.

The key acquisitions started in 2000, when the company purchased a controlling stake in Benue Cement following its privatisation. Then, in 2002, it bought Obajana Cement and started up its first production line at the site by 2007. Obajana has since become the group’s largest plant in Nigeria with a production capacity of 16.3Mt/yr across four lines. The company listed on the Nigerian Stock Exchange in 2010. Dangote Cement set up other plants in Nigeria and the Cement Manufacturing Association of Nigeria (CMAN) declared that the country was ‘self-sufficient’ in cement in 2012. Dangote the cement importer had become Dangote the cement producer. Then it became Dangote the cement exporter when it established its first overseas cement terminal in Ghana in 2011. Finally, it became Dangote the cement multinational when production plants outside of Nigeria started to be built in the early 2000s with units in Senegal and South Africa starting up in 2014. Today, in 2025, Dangote Cement has operations in Cameroon, Congo, Ethiopia, Ghana, Senegal, Sierra Leone, South Africa, Tanzania and Zambia.

Naturally, one doesn’t build a conglomerate as large and successful as Dangote Industries without dividing opinion along the way. Issues on the cement side of the business include criticism of how Dangote managed to beat his rivals to buy government-run cement companies in the early 2000s. To be fair to Dangote though, other companies including Blue Circle and HeidelbergCement did the same thing at this time. Arguments about this issue resurfaced publicly in 2022 when the Kogi State Government took Dangote Cement to court over its ownership of the Obajana plant in relation to tax revenue.

Another issue in Nigeria in recent years has been repeated arguments about the price of cement. Despite the country becoming ‘self-sufficient’ in cement, the cost has prompted scrutiny by legislators. Meanwhile, Dangote Cement has continued to make handsome profits year after year. Outside of Nigeria, Dangote’s expansion plans haven’t always gone smoothly. Its plans to open a plant in Kenya, for example, appear to have been stymied repeatedly. Infamously, Dangote himself allegedly described Kenya as being more corrupt than Nigeria to Kenyan media. A long heralded listing on the London Stock Exchange never happened and acquisitions outside of Africa are yet to occur. Looking forward, future challenges include newer entrants into the Sub-Saharan African cement such as those from China. A sign of challenges to come include the pending acquisition of Lafarge Africa by Huaxin Cement as China continues to attempt to export its cement production ambitions.

As Aliko Dangote steps down as chair from his cement business, the potential for both his company and the continent it is based in remains high. Demographic factors favour economic growth in Africa in the 21st Century due to its growing population and need for development. This will require plenty of cement and Dangote Cement is well positioned to supply it.

And finally… some people take up gardening in their retirement. Should Dangote become bored in his retirement from the cement business though he could consider the example of the former CEO of Ireland-based CRH. It was announced last week that Albert Manifold has been appointed as the chair of oil and gas company BP. Dangote Group already operates an oil refinery. Perhaps future opportunities beckon.

US: Eco Material Technologies, a marketer of supplementary cementitious materials and producer of green cement products in North America, has announced the opening of its new Lakeview Plant in southern Oregon. This milestone marks Eco Material’s first sustainably-built manufacturing hub in the Pacific Northwest.

Adjacent to Lake County's freight rail line, the Lakeview Plant can produce up to 0.3Mt/yr of low‑carbon cement replacements. By replacing 25 - 100% of traditional Portland cement in concrete mixes with Eco Material’s advanced supplementary cementitious materials (SCMs) and proprietary ‘green cement’ blends, producers can reduce the carbon footprint of the cement portion of their concrete by up to 80%.

The Lakeview plant will create 30 permanent jobs, including skilled manufacturing roles and logistics positions. Approximately 75% of shipments will be distributed by rail using existing infrastructure.

“This facility represents more than just a new plant. It’s a powerful investment in Lake County’s future,” said Mark Albertson, Lake County Commissioner. “By pairing advanced, low-carbon building materials with local job creation and infrastructure development, Eco Material Technologies is bringing both economic vitality and environmental responsibility to our community. We’re proud to welcome this transformative project while creating a great partnership to benefit all of Lake County."

France: Vicat’s sales remained stable at €1.89bn on a like-for-like basis in the first half of 2025. This was attributed to negative currency exchange effects in Brazil, Egypt and Türkiye, and a slowdown in activity in the US. Earnings before interest, taxation, depreciation and amortisation (EBITDA) fell by 2% year-on-year to €331m from €353m in the same period in 2024. Cement and concrete sales volumes dropped by 2.5% to 13.7Mt and 3.9% to 4.4Mm³ respectively. Aggregates volumes rose by 5.8% to 11.3Mt. By region sales revenue and earnings fell in France yet rose in the rest of Europe and the Mediterranean. It fell elsewhere.

“The group continues to implement its market plan, with the start-up of Kiln 6 in Senegal, a major driver of the group’s organic growth, development in the construction chemicals business with the merger between VPI and Cermix, and the acquisition of Realmix, which strengthens the group’s vertical integration in Brazil,” said Guy Sidos, Vicat’s chair and CEO.

Nigeria: BUA Cement’s sales revenue grew by 59% year-on-year to US$379m in the first half of 2025 from US$238m in the same period in 2024. Its profit after tax jumped to US$118m from US$22.4m. In its recent annual general meeting the company reported that it commissioned two new production lines at cement plants in Edo and Sokoto States in 2024 that increased its production capacity to 17Mt/yr from 11Mt/yr. It also started building a new 3Mt/yr line at Ososo in Edo State.

Germany: Vecoplan is investing over €5m to upgrade its manufacturing plant in Bad Marienberg. It has enlarged its Plant I by a total of 1900m² and purchased new production equipment. The engineering company is now adding assembly capacity and expanding its warehouse. Construction work on a new warehouse complex started in spring 2025 and is scheduled for completion in the second quarter of 2026.

“We are continuing to witness a high level of demand,” said Vecoplan’s CEO Werner Berens. “We’ve had to create additional space, especially in preassembly, to meet the growing need for our heavy machinery.”

Vecoplan manufactures machinery and plants for shredding, conveying and processing. It is headquartered in Germany and has subsidiaries in Austria, France, Italy, Poland, Spain, the US and the UK.

Algeria: The Minister of Industry Sifi Ghrieb has announced a project to build two new low-carbon cement plants in Djelfa and Relizane in central Algeria with a capacity of 1.5Mt/yr and 2Mt/yr respectively, according to Zawya news. An existing cement plant in Djelfa will also see its capacity expanded by 1.5Mt/yr.

The new projects will boost Algeria’s cement capacity to 42Mt/yr. It currently has a cement demand of 30Mt/yr and exports a surplus of 12Mt/yr of cement. Ghrief reportedly discussed plans to expand the Djelfa plant in March 2025 with a delegation from the China State Construction Engineering Corporation. A separate 2Mt/yr low-carbon cement plant, a partnership between local, UAE-based and India-based companies, is also under construction in El Milia, utilising slag and fly ash from a nearby power station and steel complex.
