Analysis

Here we go! China-based Huaxin Cement delivered a one-two combo this week by first announcing that it had completed its acquisition of Lafarge Africa from Holcim and then revealing plans to amalgamate all of its overseas businesses into a single subsidiary. The first action feeds into the second but it’s a big move for the international ambitions of the company.

Global Cement Weekly has previously covered Huaxin Cement’s deal to buy Holcim’s majority stake in Lafarge Africa for US$1bn. After being announced in December 2024 the transaction was expected to close in 2025 subject to the usual regulatory approvals. However, various impediments emerged. In March 2025 local press reported that the Senate of Nigeria asked the Bureau of Public Procurement to scrutinise the sale on the grounds of national security and economic sovereignty. A Senate Committee on Capital Market then said in May 2025 that it was going to invite Lafarge Africa for questioning to ‘ensure shareholder rights and transparency of foreign dominance in Nigeria's cement industry.’ Local company and Lafarge Africa shareholder Strategic Consultancy then initiated a legal action to try and block the sale on the grounds that it was conducted secretly and without giving local shareholders the option to buy the shares themselves. These are just the issues that have made the local press. There may be more. The transaction officially closed on 29 August 2025 with Huaxin Cement paying around US$774m. Huaxin Cement is now the majority owner of Lafarge Africa with a 83% share.

Huaxin Cement’s decision to create a specific overseas subsidiary makes sense given the growing size of the business. Its stated aim is to fulfil the group’s “long-term strategic goal of building a world-leading multinational building materials company." The acquisition of Lafarge Africa is one big milestone along this path. In the group’s half-year report, also out this week, it said it had an overseas cement grinding capacity of 24.7Mt/yr with operations in 12 countries including Cambodia, Kyrgyzstan, Malawi, Mozambique, Nepal, Oman, South Africa, Tajikistan, Tanzania, Uzbekistan, Zambia and Zimbabwe.

The new company will make and sell cement, technical services, ready-mixed concrete and aggregates. Notably, it will also specialise in the co-processing of alternative fuels. That last one is mostly implicit in any modern cement enterprise these days but as thermal substitution rates rise in developing markets there are likely to be many battles for commodities and market share ahead. It says it wants to create a new overseas subsidiary in order to “further broaden financing channels, open up and integrate resources, and enhance the operational capabilities of Huaxin Cement.” The plans are reportedly at an early stage, but the new subsidiary will remain under the control of Huaxin Cement in China. The focus on finance also seems particularly important, as the company wants to use its new subsidiary to improve its competitiveness and flexibility in overseas capital markets to help it with financing and mergers and acquisitions. To this end, the new company will be listed on an overseas stock exchange. Hong Kong might be the first contender for that ‘overseas’ bourse with its differing economic and legal systems, whilst remaining firmly Chinese.

To finish, let’s compare the contrasting business strategies of Holcim and Huaxin Cement over the last decade. Lafarge and Holcim merged in 2015, later becoming Holcim as it is today. The company divested many of its assets around the world - including Lafarge Africa, diversified into building systems and spun-off its North American division into Amrize. Huaxin Cement became one of the biggest cement companies in the world as the Chinese sector peaked in the 2010s but has also developed into the leading Chinese cement company overseas. That business outside of China has helped Huaxin Cement to make profits in recent years despite the domestic industry declining in the 2020s. Today, many large-scale cement company divestments all over the world are often linked to Huaxin Cement. Its new overseas company, whatever it is called, is likely to become well known across the world.

We return to Brazil this week where Cimento Itambé has inaugurated a new kiln at its plant in Balsa Nova, Parana. The US$92m investment has added 0.6Mt/yr of cement production capacity to the unit, bringing its total to 3Mt/yr. Notably, the new kiln is intended to support the use of alternative fuels (AF) such as biomass and industrial waste. Local press reports that the new kiln can operate with a 50% AF thermal substitution rate (TSR) and in tests it has reached as high as 67%.

Local market leader Votorantim Cimentos has also embarked on an upgrade programme linked to increasing co-processing rates. In May 2025 it said that it had received and begun installing a new cement mill, supplied from China, at its Salto de Pirapora plant near São Paulo. Earlier in August 2025 it revealed that it was spending US$60m on upgrades at its Nobres and Cuiabá plants in Mato Grosso. A new cement grinding mill is to be installed at the Nobres plant. This should increase the site’s cement production capacity to 1.2Mt/yr from 0.6Mt/yr. At Cuiabá the company is installing a tyre shredding unit via its Verdura subsidiary to support increased rates of co-processing of AF. Work on these projects is set to start in 2025 with completion scheduled by the end of 2026.

These schemes are part of the group’s larger US$920m upgrade investment plans across the country. Announced in early 2024, this is intended to increase competitiveness and co-processing capacity and reduce CO₂ emissions. It will also add 3Mt/yr to the company’s production capacity. An investment of US$150m from the International Finance Corporation (IFC) in 2023 to Votorantim to support the uptake of AF is likely to have helped the decision to upgrade. The company currently has a target of a 50% TSR by 2030.

Of the other major producers, CSN is also aiming for a 50% TSR by 2030. It said in its 2024 sustainability report that all of its kilns were capable of processing AF. It also highlighted upgrade work at its Alhandra, Paraíba, plant in 2024 to handle, store and transport fuels, including biomass. InterCement reported some relatively high TSRs at individual plants in Brazil in 2023. For example, its Ijaci plant in Minas Gerais reportedly had a rate of 42%.

National Cement Industry Union (SNIC) data shows that the co-processing rate of AF reached 32% in 2023. The union says that this puts the sector ahead of its next target of 30% in the mid-2020s. The next one is to reach 35% by 2030. For reference, back in 2019 the country’s Cement Technology Roadmap reported that around 60% of cement kilns in the country were licensed by environmental agencies to co-process waste.

Looking at the domestic industry in general, SNIC reported growth in 2024 and the first seven months of 2025. Sales for the first seven months of the year grew by 4% year-on-year to 38.2Mt. This has been attributed to the real estate sector, boosted by the Minha Casa Minha Vida housing programme, and an expanding job market. Yet jitters remain, with fears of an economic slowdown in the second half of 2025 and uncertainty on how new US tariffs might affect the cement industry indirectly. Despite only exporting around 65,000t of cement in 2024 though, the association is wary of any indirect effects of tariffs.

It’s no surprise that cement plants in Brazil are prioritising AF usage. The market is buoyant and co-processing offers one of the cheapest routes to decarbonising cement production in the short-to-medium term. Increasing the use of AF can also potentially hedge against the cost of imported conventional fuels, such as coke, that are priced in US dollars. This is one example of SNIC’s concern over indirect effects on the cement industry from US tariffs via currency volatility. Expect AF rates to carry on rising.

The 18th Global CemFuels Conference & Exhibition on alternative fuels for cement and lime will take place on 17 - 18 September 2025 in Milan, Italy

The second quarter of 2025 saw Russian GDP growth slow to 1.1% year-on-year, with a revised full-year growth forecast of 0.9%.¹ An economy bulked up on injections of military spending (budgeted at 33% of GDP in 2025)² since the invasion of Ukraine may slowly be keeling over. Faced with this eventuality, the Russian cement industry will likely be reviewing strategies not to be dragged down with the rest of the economy.

Prior to the release of the latest economic data, Russian construction had been forecast to grow at a CAGR of 2.5% in 2026 – 2029. Drivers included anticipated investments in oil and gas, transport, airports and renewable energy.

Purely in cement terms, the data no longer appear to corroborate this outlook. Market leader Cemros expects total domestic demand to drop from 67Mt in 2024, by 10 – 15% year-on-year, to 57 – 60.3Mt in 2025. In the first half of the year, Russia consumed 28.4Mt of cement, just 4% above production volumes of 27.2Mt in the same period. Cemros cited ‘declining cement consumption’ to account for its upcoming instigation of a four-day working week at its plants across Russia from October 2025.

On 12 August 2025, Cemros spoke out about a threat to the interests of the domestic industry: increased imports from Belarus. It said that Belarus’ three-plant industry is supplying Russia with cement at a rate equivalent to the combined production volumes of two-to-three cement plants. Time to cap them, it told the government, suggesting a ceiling of 1.5Mt/yr.
The producer may have received a shock on 18 August 2025, when Belarus-based Krasnoselskstroymaterialy announced an upcoming US$100m upgrade to its 700,000t/yr Vaŭkavysk cement plant in Grobno Oblast, Belarus.

By that time, the Russian cement association, Soyuzcement, had already called for an anti-dumping investigation into all cement imports. It expects that import volumes of 3.74Mt in 2024 may rise to 5Mt/yr ‘in the near-term future.’

Lingering behind these discussions is the fact of high operating costs, partly precipitated by Russia’s continuing burden of international sanctions.

Here, the cement sector’s hopes are riding on a very particular marketing campaign: that of President Vladimir Putin on the global diplomatic circuit. He must sell his war (or peace on his terms) in a way that fends off increased international sanctions or support for Ukraine. Existing sanctions were on show at the Alaska Summit in Anchorage, US, on 15 August 2025, where the Russian leader made his pitch to US President Donald Trump – including a request for de-sanctioning, alongside various proposed punishment measures against Ukraine. Before travelling back to Moscow, the Russian delegation reportedly had to offer to pay cash for aeroplane fuel.³

Though President Trump did not secure a ceasefire, he nonetheless held back from making good on threatened new sanctions, and rated the Alaska Summit ‘10/10.’⁴ Putin might be equally pleased with the inconclusive outcome as precisely the goal of all his obfuscations. For Russia’s cement producers, costs won’t suddenly rise, but nor will they come down any time soon.

Far from sitting idly by, the industry is seeking new ways to actualise the value of its product. On 20 August 2025, Soyuzcement hosted a meeting of nine producers and four retail chains to strategise ways to increase sales of bagged cement. It will be subject to mandatory digital labelling from 1 October 2025. Discussions included the possibility of batch labelling of bags on the pallet for ease of scanning at retail outlets.

For now, producers’ online media spaces give the impression of work continuing as usual. On 18 August 2025, Cemros announced a US$186,000 renovation of buildings at its Mikhailovsk building materials plant in Volgograd Oblast.

The cement business in Russia is big, established and diffuse. Transformation has been its defining feature in the 33 years since the fall of the USSR, including in the relatively stable latter decades of that period. Should macroeconomic or geopolitical events overtake it once again, we can expect some shapeshifting – but also survival.

Ecocem announced this week that it has achieved certification in the US for its ACT low-carbon cement technology. This follows CRH’s agreement to buy US-based Eco Material Technologies, a supplier of supplementary cementitious materials (SCM), which was revealed in late July 2025. These moves and others mark a flurry of activity by various companies in the US SCM sector in recent months.

Donal O’Riain, the founder and managing director of Ireland-based Ecocem, underlined the importance of certification in North America when he said that “The US is one of the largest cement markets in the world, and this certification will support integration into existing supply chains and offers a pathway for the sector to rapidly decarbonise.” The country imported just under a fifth, 19Mt, of its Portland and blended cement in 2024 according to the United States Geological Survey (USGS).

Ecocem started out as a manufacturer of cements made using ground granulated blast furnace slag (GGBS), a SCM, in the early 2000s. Its ACT technology was formally announced in 2022. It is described as a process that can make cements using “available fillers like limestone and local SCMs.” It is currently scheduled for a commercial launch in 2026, starting in France. In the US it is planning to build a terminal and mill at the Port of Los Angeles in California. This follows a previous attempt to build a slag grinding plant, also in California, in the 2010s.

CRH, another cement company with strong links to Ireland incidentally, said on 29 July 2025 that it had agreed to acquire Eco Material for US$2.1bn. The latter operates a network of fly ash, pozzolan, synthetic gypsum and green cement operations. It partners with electricity generators to process about 7Mt/yr of fly ash and 3Mt/yr of synthetic gypsum and other materials. As CRH’s CEO Jim Mintern put it, “this transaction secures the long-term supply of critical materials for future growth and puts CRH at the forefront of the transition to next generation cement and concrete.” The deal is expected to close by the end of 2025. In separate comments to analysts Mintern added that he expects the market for SCMs to double in the US by 2050.

Other players have also been busy in recent months. Amrize, for example, noted in its financial results for the second quarter of 2025 that it had broken ground on a new fly ash beneficiation facility in Virginia in the reporting period. Last week, Graymont and Fortera signed an agreement to produce Fortera’s ReAct low-carbon cement product by using Graymont’s existing lime production operations. Fortera runs a plant in Redding, California that takes captured CO₂ from the adjacent CalPortland cement plant and uses it to manufacture its own proprietary SCM. Back in April 2025 Buzzi Unicem said that it had partnered with Queens Carbon to produce a novel cement and SCM. The start-up was intending to build a 2000t/yr demonstration plant at Buzzi Unicem’s cement plant in Stockertown, Pennsylvania.

The backdrop to all of this attention on SCMs in the US are the cost of cement and sustainability. Using more SCMs reduces clinker usage in cement and it can reduce the cost. At the same time reducing the amount of clinker used decreases the amount of CO₂ emissions. So, for example, Ecocem says that its ACT technology can reduce CO₂ emissions by up to 70% compared to conventional cement.

A report by Mckinsey on SCMs in the autumn of 2024 reckoned that growth in the cement market in North America was expected to be ‘robust’ in the next 15 years to 2050. However, the sector faces material, particularly clinker, and labour shortages. Enter SCMs! It went on to assert that much of the available stocks of GGBS and fly ash in the country are effectively used. Yet, traditional industrial SCMs such as GGBS, fly ash and limestone are anticipated to be available for longer than in Europe as industries such as steel manufacture and electricity generation will take longer to decarbonise. Hence companies such as Ecocem are preparing to import them, ones like CRH are cornering existing stocks and others such as Fortera and Queens Carbon are working on creating their own ‘virgin’ sources. At the same time the American Cement Association has been promoting the use of Portland Limestone Cement in the country.

All this helps to explain the interest in SCMs in the US right now. It’s a busy moment.

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.
