Global: The World Cement Association (WCA) projects a 22% decline in global cement demand by 2050. Price increases are expected to continue in European and North American markets, while significant market restructuring is already underway to address overcapacity in China and Japan. Multinational companies are scaling back cement business and focusing instead on North America, while cement production in Europe continues to decline due to strict CO₂ regulations and capacity reductions.

India's cement production has surpassed 200Mt/yr, with domestic firms strengthening their position as multinationals exit the market. Chinese producers are expanding their presence, particularly in Africa and Southeast Asia.

WCA president Wei Rushan said “To remain both profitable and environmentally responsible, the cement industry must aim to reduce capacity by 50%, from 4.7Bnt/yr to 2.3Bnt/yr within the next decade. This requires focusing on modern, sustainable production units.”

Northern-Ireland based cement producer Cemcor said this week that it has completed trials of a calcined clay cement product called CalcinX. The company started its trials in 2023 and it has been supported by Queen’s University Belfast and funding from Innovate UK. Work with commercial partners has involved precast concrete paving manufacturer Tobermore producing paviours made from 50% CalcinX as a CEM II replacement and Moore Concrete has also manufactured precast units using 50% CalcinX as a CEM I replacement. So far over 3000t of CalcinX has been produced in a number of industrial-scale trials.

David Millar, the managing director of Cemcor, mentioned his company’s plans for calcined clay in June 2022 when he was interviewed by Global Cement Magazine. The company that became Cemcor bought the Cookstown cement plant and a few other assets from Holcim at the start of 2022. It then changed its name to Cemcor in November 2022. At the time of the interview the company was looking to “...develop new value-added products, including low-CO₂ options. This will allow us to use the same amount of clinker to produce more cement.” Millar couldn’t give away too many details at the time, however calcined clay was cited specifically. It was also noted that the company had the right material in its quarry and that it was already working with partners on it.

Amongst all the other decarbonisation options available for cement plants, a slow trickle of calcined clay projects keep being announced. In January 2025, for example, thyssenkrupp Polysius said it had secured a front-end engineering design contract from Circlua for the construction of the world’s largest activated clay plant in Brazil. This project in Para state will have a capacity of 3000t/day, will use renewable energy sources and will “improve the CO₂ footprint in cement production.” CBMI Construction also officially launched a flash calcination clay project in Tangshan, Hebei province in China. In December 2024, Vicat signed an agreement with the US Department of Energy (DOE) Office of Clean Energy Demonstrations to develop the Lebec Net Zero (LNZ) project at its Lebec cement plant in California. This includes plans to produce calcined clay-based cement. Earlier in the autumn of 2024 Portugal-based Cimpor said it was preparing to convert a kiln at its Souselas plant to produce calcined clays, AVIC International Beijing and KHD said that they had secured a deal to build a 900t/day clay calcination plant for Ciments de l'Afrique (CIMAF) in Burkina Faso, and Holcim Česko said it was going to construct a calcined clay processing line at the Čížkovice cement plant in the Czech Republic.

One news story that stuck out in the autumn was the progress of a collaboration between Aumund and Holcim towards developing an electric linear calcination conveyor (eLCC). The two companies started work on the project in 2020 intending to look at the electrical calcination of clay using an Aumund pan conveyor. Initial tests of the eLCC reportedly demonstrated efficient thermal activation of clay through a combination of radiant heat and material circulation. The eLCC system is fully enclosed, insulated, has a compact design and can operate using electrical-powered renewable sources. The first industrial plant utilising this technology is scheduled for construction in 2025. Calcined clay technology and products by other industrial suppliers are available. The work by Aumund and its competitors show they are watching this market closely.

OneStone Consulting’s Joe Harder has found that only 14 clay calcination plants were operational worldwide in 2023 with a production capacity of just under 3.5Mt/yr. These are based in Latin America, Europe and Africa. In an article previewing a market report in the February 2025 issue of Global Cement Magazine, Harder predicts that by 2035 there will be 79 clay calcination plants with a capacity of just under 21Mt/yr. A steady growth of over 20 new plants annually is also expected subsequently from 2035 to 2050 as cement producers seek cost-effective ways to reduce their clinker factor. He identified installation costs, a lack of knowledge about clay-based cements, trouble obtaining mining rights and policy issues amongst other issues as holding back the use of clay calcination.

The current expectation is that calcined clay usage in the cement industry will be a minority option. Yet the size of global cement production can make a production share of, say, 3 - 8% a viable option for both cement manufacturers and equipment suppliers. The adoption of new cement products and standards can also take a long time and this clouds predictions of how far clay can go in the cement industry. At this point in the calcined clay story it is time to keep track of the new projects being set up.

Joe Harder will present a talk entitled ‘Calcined clay market trends by 2035’ at the Global FutureCem Conference taking place in Istanbul in early February 2025

UK: Cemvision has launched one of the UK’s first commercial applications of its low-carbon Re-ment cement technology at a STOREX self storage development in Sunbury, near London. The foundational slabs for the site employ Cemvision's Re-ment Massive product, which replaces traditional Portland cement. Recent laboratory tests have shown that the product achieves a 75% CO₂ reduction and a 28-day compressive strength, that reaches the C50/60 classification, compared to traditional Portland cement. STOREX and Cemvision have signed a Letter of Intent for further collaboration in the UK and other markets.

“This project is a landmark achievement for Cemvision as we bring the benefits of green cement to UK customers,” said Oscar Hållén, CEO of Cemvision.

Cemvision says that its Re-Ment Massive technology reaches different levels of CO₂ reduction depending on application and local conditions, with the product already having achieved more than a 95% reduction compared to Portland cement in demo production in the EU, according to the company.

UK/Ireland: France-based Hoffmann Green Cement Technologies has launched a strategic licensing agreement with UK partner Cemblend, furthering its international expansion strategy. The deal builds on an existing partnership established in 2022 for the launch of Hoffmann’s 0% clinker cements, with the partners aiming to accelerate the decarbonisation of the construction sectors in the UK and Ireland. Under the terms of the agreement, Hoffmann Green will receive up to €2m in entry fees and annual royalties tied to the sales of Hoffmann cements and premixes. Cemblend will construct production units in the UK to support the rising demand for sustainable building materials.

Thomas Atkinson, international director of Hoffmann Green Cement Technologies, said “2024 marks a key period in Hoffmann Green's international development. After signing a strategic partnership in the US and strengthening our development in Saudi Arabia, this new licensing agreement provides us with ambitious new perspectives on the European market.”

UK: The first shipment of bulk cementitious materials has arrived at Aggregate Industries’ new deep-sea cement terminal in Southampton.

Cementitious materials are conveyed pneumatically into the terminal’s new warehouse. The facility, developed under a €7.2m investment, is reportedly the UK’s fastest cement discharging terminal, unloading 1t of cement every five seconds. The project began in March 2024 and was completed with the arrival of the Nacc Indian Cement Carrier, marking the terminal’s operational launch.

UK: Nuada and Carbfix have signed a memorandum of understanding to deliver integrated carbon capture and storage (CCS) solutions targeting emissions reduction in the cement, lime, steel, waste-to-energy and bioenergy sectors. The partnership combines Nuada’s carbon capture technology with Carbfix’s underground CO₂ mineralisation method.

Nuada’s technology uses solid sorbents, metal organic frameworks, and vacuum pressure swing adsorption to capture CO₂ from the source while addressing barriers like energy consumption and cost. Carbfix’s storage method accelerates the mineralisation process by injecting CO₂ into basaltic rock, where it reportedly transforms permanently into stone within two years.

UK: Material Evolution has launched its 'ultra-low carbon' cement production plant, Mevo A1, in Wrexham. The facility was commissioned in October 2024 and operates on an industrial scale with a capacity to produce 120,000t/yr of its MevoCem product, which the company claims can achieve up to 85% emissions reductions compared to ordinary Portland cement. The plant uses Material Evolution's alkali-fusion process that doesn’t require heat or a kiln, producing a cement capable of undergoing geopolymerisation.

Sam Clark, co-founder and chief operating officer said "This launch takes us one step closer to achieving our goal of removing one gigaton of CO₂ by 2040."

UK: Aggregate Industries has built a 45m high and 32m diameter airform dome silo at the Port of Tilbury in Essex. The silo is part of its new cement import, manufacturing and distribution facility, which is under construction. The inflatable structure will store up to 30,000t of cement to support demand for construction materials in the region. Aggregate Industries worked with US-based Dome Technology to inflate the dome. Contractor Dome Technology will now apply nearly 4500m³ of sprayed and wet mix concrete to form the dome silo.

The cement facility is expected to be operational in 2026.

Thailand/UK: Thailand-based Siam Cement Thung Song has joined the World Cement Association as a corporate member. The cement producer is a subsidiary of Siam Cement Group that operates an integrated plant in the south of the country.

UK: Heidelberg Materials UK has launched evoBuild, a global brand for low-carbon and circular cement, ready-mixed concrete, aggregates and asphalt products, in line with its parent company's sustainability strategy. According to the company, EvoBuild products either reduce CO₂ emissions by at least 30% or incorporate at least 30% recycled content.

This launch complements evoZero, the ‘world's first carbon-captured net-zero cement’, launched by Heidelberg Materials in November 2023. All eligible products from Heidelberg Materials UK will be integrated into the evoBuild portfolio ‘over the coming years.’
