US: Ash Grove Cement, part of CRH, has deployed Boston Dynamics’ autonomous robot ‘Spot’ at its cement plant in Washington in a year-long pilot to boost efficiency and safety. Operating more than 80 hours a week, the four-legged robot conducts routine inspections using a 4K camera and laser scanning, detecting anomalies and alerting teams before failures occur.

The company said that the robot can measure refractory bricks inside cement kilns, reducing risks by keeping employees out of hazardous environments. During the trial, Spot detected a failing bearing in rotating equipment, preventing unplanned downtime. Ash Grove said that the technology improves site safety, frees skilled teams for complex work and enables real-time monitoring in the hot and dusty conditions at the plant.

Plant manager Andy White said “Our aim for Spot is that, at the moment, we don’t have preventative or proactive maintenance routines on night shifts and the weekends. And, also, our labour force has to spend a lot of time recording data rather than analysing it… Spot can do this for us. When we come in the mornings, we already have reported generated, so we can proactively fix those issues thather than spending eight hours trying to find them.”

US: Martin Engineering has launched its two-wheeled Martin Gen 4 Railcar Opener. It is designed to aid bulk handlers to unload unprocessed and processed bulk materials from rail transport to facilities, including cement plants and terminals. The fourth generation product is intended to improve ease of use and reduce potential hazards for workers.

Features of the latest version of the railcar opener include simple manoeuvrability and lateral turning wheels for moving capstans, outrigger support and height adjustment. A ‘stepped’ drive tip is also intended to improve the gate opener’s contact with the capstan. This new design boosts efficiency, leading to less demurrage from stalling and a safer workplace.

Marty Yepsen, Business Development Manager for Railcar Unloading Products at Martin Engineering said “We’re excited about the 4th generation of this model because it’s been painstakingly designed over years using real-world feedback from customers.” He continued, “The nearly effortless single operator design transforms a hazardous and gruelling job into a comparatively routine and risk-free task,” Yepsen concluded. “Field tests have shown that the Gen 4 not only improves efficiency, which lowers demurrage, but it also increases safety and reduces labour costs. All this drives down operating costs and boosts ROI.”

Martin Engineering builds products for bulk materials handling. The company has its headquarters in Neponset, Illinois. It runs subsidiaries in Australia, Brazil, China, Colombia, France, Germany, India, Kazakhstan, Indonesia, Malaysia, Mexico, Peru, Spain, South Africa, Türkiye, the UK and the US.

China/US: A team led by Fengyin Du, then at Southeast University in Nanjing, developed a new cement formulation that reflects sunlight and emits heat more effectively than ordinary Portland cement, according to the New Scientist. The cement incorporates reflective ettringite crystals on its surface, which Du says “works like a mirror and a radiator, so it can reflect sunlight away and send heat out into the sky, so a building can stay cooler without any air conditioning or electricity.”

To make it, the researchers produce tiny pellets from limestone and gypsum, which are ground and mixed with water before being poured into a silicone mould covered in small holes. Ettringite crystals grow in slight depressions on the surface created by air bubbles, while an aluminium-rich gel allows infrared light to pass through, lowering heat retention.

Du said that tests at Purdue University, Indiana showed the cement’s surface was 5.4°C cooler than the air and 26°C cooler than conventional cement under the same conditions. The process is reportedly scalable and costs US$5/t less than ordinary Portland cement, as it can be produced at lower temperatures.

Algeria: Biskria Ciment has exported 28,000t of white cement to the US from the port of Annaba aboard the M/V Anhui, according to the Annaba Port Company via L’Expression newspaper. The exports continue despite a 30% US customs duty on Algerian imports.

The company said it is maintaining shipments by leveraging the quality and price competitiveness of its cement.

US: Shipments of Portland and blended cement, including imports, fell by 7.5% year-on-year to 8.91Mt in May 2025, according to the latest figures from the United States Geological Survey (USGS). Shipments for January to May 2025 totalled 37.9Mt, down by 6% from the same period in 2024. Texas, Missouri, California, Florida and Michigan accounted for 39% of production, while Texas, California, Florida, Ohio and Illinois received 40% of shipments.

Clinker production was 6.38Mt in May 2025 , compared with 6.46Mt in May 2024. For January to May 2025, clinker output dropped by 10% to 24.5Mt. Imports for the period declined by 5% year-on-year to 9.81Mt.

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.

Mexico: Cement consumption fell by 8 – 10% in the first half of 2025 compared to the same period of 2024, according to José María Barroso Martínez, CEO of Cementos Moctezuma. He attributed the drop to factors such as the change of government in Mexico, the US government's tariff policy, a decrease in small-scale private works and on-going negotiations towards a replacement for the United States – Mexico – Canada Agreement (USMCA) for North American free trade, among other factors.

In an interview with Grupo Reforma News, Martínez said “Cement is the first variable that moves when the economy accelerates or decelerates. In the second half of 2025 we can achieve additional volumes to correct the trend and close the year similar 2024, when the industry reached close to 42Mt sold."

US: Hollingshead Cement, a division of SRM Concrete, has opened a cement terminal in Chattanooga, Tennessee, on the same site as an SRM Concrete ready-mix plant and block production facility. The terminal will receive cement by rail and can store over 50,000t.

SRM Concrete CEO Jeff Hollingshead said “We are excited to begin distributing cement from our new facility in Chattanooga. With this investment, we are better positioned to ensure a consistent and reliable supply of cement across our entire network of ready-mix and block locations, while also serving our cement customers with greater efficiency.”

The facility is the eleventh in Hollingshead Cement’s US terminal network, which supplies bulk cement for multiple construction applications.

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.

US: Ecocem has obtained ASTM C1157 certification for its ACT low-CO₂ cement technology, confirming it meets or exceeds strength and durability benchmarks while reducing emissions and energy use. Unlike traditional cement specifications, the standard is performance-based, allowing for innovative formulations.

Founder and group managing director Donal O’Riain said “This is a significant moment for Ecocem and for low-carbon cement globally. Over the past 10 years our solutions have seen significant traction across Europe. 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 through improved efficiency and without increasing costs or complexity.”

Ecocem is advancing its first North American project, a proposed terminal and milling operation at the Port of Los Angeles, aimed at establishing a reliable low-CO₂ cement supply chain in California. The company says that its low-carbon cement technology, ACT, cuts clinker content by up to 70% by using limestone and locally-sourced supplementary cementitious materials. The announcement follows recent regulatory approvals in France, new investment in production lines in Dunkirk, and partnerships with Bouygues, Vinci and Titan Group.
