Another potentially gargantuan deal in the US building materials sector emerged this week in the shape of Quikrete bidding to buy Summit Materials. The latter company announced that a non-binding acquisition proposal had been received and the business press revealed who it was from. Further reporting suggested that Summit Materials has a market value of around US$7bn.

Quikrete is well known in North America for its packaged concrete products that are often sold in distinctive yellow bags. Its brands include Quikrete cement and concrete, Pavestone and Keystone paver and block products and Rinker concrete pipe and storm-water products amongst others. The company says it operates over 90 manufacturing sites in the US, Canada, Puerto Rico and South America, although it does not appear to own any cement plants. Notably, it is privately owned.

The deal is likely to revolve around the ready-mixed concrete assets that Summit Materials runs. However, readers may recall that Summit Materials and Cementos Argos completed the merger of their operations in the US at the start of 2024. That deal was set to make Colombia-based Cementos Argos the largest shareholder in Summit Materials. The companies also said that it was going to set them up with the fourth-largest cement-making portfolio in the US, with a capacity of 11.6Mt/yr, and place them among the largest aggregates and concrete producers. So it will be interesting, to say the least, to see how Cementos Argos reacts to a change in plans so soon after the merger has finished. Assuming the deal is credible, how it reacts may suggest whether the company is following the money in the short term or sticking to a longer plan.

Yet another large deal in the building materials sector in North America reinforces the diverging fortunes between the markets there and in Europe. However, this dynamic can create its own problems. Holcim’s grand spin-off of its business in North America, for example, appeared to be downgraded in the group’s third quarter results to a ‘mere’ dual listing. Press reports suggest that its Swiss and other European shareholders are facing restrictions from holding shares outside of their home markets.

Despite the current frenzy for market share and margin in the US by multinational building materials companies though, the cement market hasn’t had the best year so far in 2024. US cement shipments actually fell year-on-year in 2023 and continued to do so during the first seven months of 2024, according to United States Geological Survey (USGS) data. The Portland Cement Association (PCA)’s Chief Economist Ed Sullivan blamed this mainly on high interest rates. He then noted in an autumn forecast that a cut in rates was likely to benefit the construction market from mid-2025 onwards. Anne Noonan, the CEO of Summit Materials, also noted the negative effect of interest rates on construction projects at a recent Colorado Business Roundtable event.

None of this has discouraged the hunger of companies to cash in on the US market. Even the uncertainty of the impending US presidential election taking place on 5 November 2024 has failed to quell this desire. In brief, either administration might take different approaches to trade protectionism, infrastructure investment plans, green investment, permitting, regulations and so on. Yet the market fundamentals are strong for building materials. Koch helped MITER Brands buy window and door manufacturer PGT Innovations for US$3.1bn in January 2024 and Owens Corning acquired another door producer, Masonite, for US$3.9bn in May 2024. Quikrete smells potential and it may follow.

US: Eagle Materials' quarterly revenues hit US$624m in the first half of the 2025 financial year, with net earnings of US$144m and earnings before interest, taxation, depreciation and amortisation (EBITDA) of US$242m. The company’s cement revenues dropped by 2% year-on-year, to US$353m, resulting in a 5% fall in its operating earnings from cement, to US$116m, exacerbated by increased maintenance costs. Cement sales volume declined by 5% year-on-year to 2Mt, affected by adverse weather in Texas in July 2024 and Eastern US markets in September 2024.

US: Terra CO₂ has received a US$52.6m federal grant from the US Department of Energy to support the construction of a new plant in Magna, Utah, that will produce up to 240,000t/yr of supplementary cementitious materials using mining waste from the nearby Kennecott copper mine. This method reportedly aims to cut CO₂ emissions by 70% per tonne of traditional cement replaced, according to the company’s CEO Bill Yearsley. The project is expected to create 61 jobs.

US: Bagged concrete and cement mixes producer Quikrete has submitted an acquisition offer to cement, concrete and aggregates company Summit Materials. Summit Materials is reportedly valued at over US$7bn. The company confirmed to Reuters that its board is in initial discussions over a non-binding acquisition proposal.

Summit Materials combined its business with Cementos Argos subsidiary Argos USA in January 2024.

US: California-based climate technology startup Furno Materials has been awarded US$20m by the US Department of Energy (DOE) for a new ‘low-carbon’ cement production facility in Chicago. The facility will use recycled industrial byproducts to produce cement, with the aim to reduce carbon emissions ‘significantly’, according to the Chicago Business Journal. This investment is part of a broader DOE initiative that is funding 14 projects totalling US$428m, in order to address clean-energy supply chains and boost US manufacturing. The project is expected to create 80 jobs.

Starlinger revealed this week that it had taken on copycats in China and won. The packaging machine manufacturer said that it had sued a number of China-based machine manufacturers and their customers, packaging producers, based on infringement of several of its patents. An out-of-court settlement was eventually reached with the case going before both a civil court and a Chinese court specialised in intellectual property. Naturally, Austria-based Starlinger did not say what the settlement involved other than stating that the proceedings had been “...settled with strict obligations for the machine manufacturers.”

It’s unclear how directly the case affected the cement sector. Starlinger did say that the case involved a replica of a proprietary sack conversion line for producing woven plastic sacks. Packaging producers, often in Asia, use Starlinger’s conversion lines to manufacture proprietary block bottom valve sacks made of polypropylene tape fabric for the cement and construction industries, although they are also used for other dry bulk goods such as rice, flour or chemical granulates.

Starlinger’s reasons for going public are interesting given that most companies steer well clear of discussing legal matters openly. In the accompanying press statement Harald Neumüller, the chief strategy officer of Starlinger, used the disclosure to promote his products by saying “Only the best are copied, as the saying goes.” He then went on to underline the company’s strengths in research and development. Yet he also admitted that this was “...little consolation if it has economic consequences for innovative machine manufacturers like us.”

Firstly it should be noted that battles over patents and ideas happen everywhere from time to time. Discussing international copyright theft has become politicised because it plays into the geopolitical rivalry between the US, Europe and China. One US-government commissioned estimate in 2017 reckoned that the US economy was losing US$225 - 600bn/yr due to counterfeit goods, pirated software and theft of trade secrets. This report has been criticised but it gives one an idea of the scale of the concern. However, there are also plenty of prognosticators in the western media who have spent the last two decades warning of a hard landing in the Chinese economy that hasn’t happened.

Bringing this discussion back to cement, following the collapse of the real estate market since 2021, cement output has fallen. Data from the National Bureau of Statistics of China shows that output decreased by 11% year-on-year to 1.33Bnt in the nine months from January to September 2024. This appears to be following a similar decline in local real estate investment. The market is still correcting itself and the government is making gradual changes but there has been no apparent cataclysm so far. China-based equipment suppliers don’t appear to have suffered to the same degree due to their foreign orders.

The standard western narrative is that when European or American companies sold their equipment in China from the 1990s onwards they contended with a rocketing economy and lax intellectual property (IP) enforcement. Such an environment reputedly made it easy for some local companies to copy machinery and sell it more cheaply. At the same time China’s industries legitimately surpassed their competitors leading to criticism about how they did it. Publicly available evidence of this behaviour in the cement sector is limited. One of the few includes action by Haver & Boecker, another packaging machine manufacturer, in the late 2010s. However, anecdotally, the view that IP was stolen in China is prevalent in the west whether it is true or false. No doubt readers will have their own experiences and opinions. None of which would be publishable. The issue has been superseded though as China’s cement sector has become the largest in the world by a considerable margin. The biggest manufacturers of cement plants in the world are now Chinese companies too. They either use their own equipment or buy in western kit depending on what the customer wants. They also own a number of their overseas competitors and more potential acquisitions look likely.

All of this is what makes Starlinger’s admission unusual. It has taken a stand and it may have paid off. At the very least the equipment supplier is wringing publicity out of the affair regardless of how big - or small - the settlement may have been. Others may follow.

Switzerland/US: Holcim may list its upcoming market-separated North American business both in the US and Switzerland, Bloomberg has reported. The possibility arose due to Swiss and European restrictions on foreign shareholdings for locally-based funds, which may result in sales of Holcim stocks, with negative price impacts. On the other hand, a dual listing could potentially reduce the liquidity of any future US-listed shares.

SeeNews has reported that Holcim North America will be headquartered in Zug, Switzerland, for tax ‘advantages,’ while operating out of Chicago, US.

One unusual thing about coverage of cement in the media is the way that discussions often centre precisely on its absence – that is, on alternatives to cement. These alternatives boast unique chemistries and performance characteristics, but are all produced without Portland cement clinker. They are generally called ‘alternative cements,’ perhaps because ‘cement-free cement’ does not have such a commercially viable ring to it. This contradictory tendency reached a new high in the past week, with developments in alternative cement across Asia, Europe, the Middle East and North America. Together, they hint at a more diverse future for the ‘cement’ industry than the one we know today.

Asia

In Indonesia, Suvo Strategic Minerals has concluded tests with Makassar State University of a novel nickel-slag-based cement. Huadi Nickel-Alloy Indonesia supplied raw materials, and tests showed a seven-day compressive strength of 37.5MPa. Suvo Strategic Minerals says that a partnership with Huadi Nickel-Alloy Indonesia for commercial production is a likely next step.

Europe

Cement producer Mannok and minerals company Boliden partnered with the South Eastern Applied Materials (SEAM) research centre in Ireland to launch a project to develop supplementary cementitious materials (SCMs) from shale on 7 October 2024. The project will additionally investigate CO₂-curing of cement paste backfill for use in mines. Irish state-owned global commerce agency Enterprise Ireland has contributed €700,000 in funding.

UK-based SCM developer Karbonite expects to launch trial production of its olivine-based SCM with a concrete company in 2025. The start-up launched Karbonite Group Holding BV, with offices in the Netherlands, to facilitate this new phase. Karbonite’s SCM is activated at 750 – 850°C and sequesters CO₂ in the activation process, resulting in over 56% lower CO₂ emissions than ordinary Portland cement (OPC). Managing director Rajeev Sood told Global Cement that talks are already underway for subsequent expansions into the UAE and India.

Back in the UK, contractor John Sisk & Son has received €597,000 from national innovation agency Innovate UK. John Sisk & Son is testing fellow Ireland-based company Ecocem’s <25% clinker cement technology in concrete for use in its on-going construction of the Wembley Park mixed development in London.

At the same time, Innovate UK granted a further €3.23m to other companies for concrete decarbonisation. Recipients included a calcined clay being developed by Cemcor, an SCM being developed from electric arc furnace byproducts by Cocoon, a geopolymer cement technology being developed by EFC Green Concrete Technology UK and an initiative to develop alternative cement from recycled concrete fines at the Materials Processing Institute in Middlesbrough. Also included was the Skanska Costain Strabag joint venture, which is working on the London stretch of the upcoming HS2 railway. The joint venture, along with partners including cement producer Tarmac and construction chemicals company Sika UK, will test low-kaolinite London clay as a raw material with which to produce calcined clay as a cement substitute in concrete structures in HS2’s rail tunnels.

Middle East

Talks are underway between UK-based calcined clay producer Next Generation SCM and City Cement subsidiary Nizak Mining Company over the possible launch of a joint venture in Riyadh, Saudi Arabia. The joint venture would build a 350,000t/yr reduced-CO₂ concrete plant, which would use alternative cement based on Next Generation SCM’s calcined clay.

North America

Texas-based SCM developer Solidia Technologies recently patented its carbonatable calcium silicate-based alternative cement, which sequesters CO₂ as it cures.

Meanwhile, C-Crete Technologies made its first commercial pour of its granite-based cement-free concrete in New York, US. C-Crete Technologies says that the product offers cost and performance parity with conventional cement, with net zero CO₂ emissions. Its raw material is globally more abundant than the limestone used as a raw material for clinker. Other abundantly available feedstocks successfully deployed within C-Crete Technologies’ repertoire include basalt and zeolite.

Across New York State, in Binghamton, KLAW Industries has succeeded in replacing 20% of concrete’s cement content with its powdered glass-based SCM, Pantheon. KLAW Industries has delivered samples to local municipalities and the New York State Department of Transportation. Its success expands the discussion of possible circular cement ingredients from the industrial sphere into post-consumer resources.

In Calgary, Canada, a novel SCM has drawn attention from one of the major cement incumbents: Germany-based Heidelberg Materials. It invested in local construction and demolition materials (CDM)-based SCM developer EnviCore on 9 October 2024. The companies plan to build a pilot plant at an existing Heidelberg Materials CDM recycling centre.

Conclusion

Alternative cement developers are still finding the words to talk about their products. They may be more than ‘supplementary’ up to the point of entirely supplanting 100% of clinker. Product webpages offer ‘hydraulic binder,’ ‘pozzolan’ and even ‘cement.’ As alternative ‘cements’ are developed, they build on the work of pioneers like Joseph Aspdin and Louis Vicat. Start-ups and their backers are now reaching commercial offerings, on a similar-but-different footing to cement itself. None of these novel materials positions itself as the sole, last-minute ‘super sub’ in the construction sector’s confrontation with climate change. Rather, they are a package of solutions which can combine into a net zero-emissions heavy building materials offering, hopefully before 2050.

Related to this is the need for ‘technology neutral’ standards, as championed this week by the Alliance for Low-Carbon Cement and Concrete (ALCCC), along with 23 other European industry associations, civil society organisations and think tanks. The term may sound new, but the concept is critical to the eventual uptake of alternative cements: standards, the ALCCC says, should be purely performance-based. They ought not attempt to define what technology, for example cement clinker, makes a suitable building material. According to the ALCCC, Europe’s building materials standards are not technology neutral, but instead ‘gatekeep’ market access, to the benefit of conventional cement and the exclusion of ‘proven and scalable low-carbon products.’

At the same time, cement itself is changing. Market research from USD Analytics showed an anticipated 5% composite annual growth rate in blended cement sales between 2024 and 2032, more than doubling throughout the period from US$253bn to US$369bn. If you can’t beat it, blend with it!

For a further discussion of alternative cement and binders in Europe, see Global Cement’s interview with ALCCC co-ordinator Joren Verschaeve in the forthcoming November issue of Global Cement Magazine on 17 October 2024.

US: Researchers at UCLA's Institute for Carbon Management have developed a new method called ZeroCAL that could eliminate ‘nearly all’ of the carbon dioxide emissions from the process of cement production, according to the UCLA Newsroom. The team created a process using limestone and a water-based solution containing ethylenediaminetetraacetic acid. Through membrane nanofiltration and an electrochemical process, they produced calcium hydroxide.

To meet ZeroCAL’s water demand, the team suggests focusing on cement plants near coasts or rivers. The researchers are reportedly working with Ultratech Cement to build a demonstration plant that will produce ‘several’ tonnes of lime per day using the ZeroCAL process. Currently, the process requires more energy than traditional lime production methods, but ongoing research aims to reduce its energy consumption.

Gaurav Sant, director of the Institute and professor at UCLA Samueli School of Engineering, said “The ZeroCAL approach offers an elegant solution to eliminate carbon dioxide emissions associated with the process of cement production. First, it addresses the carbon emissions resulting from limestone’s decomposition while providing clean hydrogen and oxygen to heat the cement kiln. Second, it enables onsite decarbonisation while making use of existing kilns and limestone feedstocks without having to build separate carbon capture and storage facilities.”

US: C-Crete Technologies has poured its granite-based cement-free concrete in its first construction application at the upcoming JPMorgan Chase headquarters at 270 Park Avenue, Manhattan. Ecology, Environment and Conservation News has reported that the concrete generates no net CO₂ emissions by sequestering atmospheric CO₂ in its curing process. The concrete conforms to ASTM International standards, with a compressive strength exceeding 5000psi. Other partners on the project included engineering firm Severud Associates Consulting Engineers and construction management firm AECOM Tishman.

C-Crete Technologies president Rouzbeh Savary said "We are thrilled to introduce our new granite-based concrete at such a prestigious and iconic location. The building at 270 Park Avenue is set to become a landmark not only for its architectural grandeur, but also for its sustainable construction practices."

Severud Associates Consulting Engineers senior associate Fortunato Orlando said "The performance of C-Crete for concrete on metal deck, topping slabs, pavements and landscape work, coupled with its eco-friendly attributes, makes it a revolutionary product for the future of the construction industry."

AECOM Tishman chief operating officer John Kovacs said "Just a few years ago, constructing devoid of Portland cement and CO₂ emissions would have seemed unimaginable. And yet today, we stand as the world's first, setting new thresholds of what's possible in sustainable construction. We thank all of our partners on this project and look forward to the day when CO₂ emission-free construction is not simply an idea or a new innovation, but the industry standard across every build."
