Switzerland: After 128 years as a family-operated business in Grandson, Vaud, Cand-Landi will become a subsidiary of Holcim Group. This acquisition marks an expansion for Holcim in the areas of aggregate and concrete production, as well as landfill management.

The terms of the transaction, including the financial details, have not been disclosed. However, the Cand-Landi name will be kept after the acquisition.

India: Shree Cement has ventured into the ready-mix concrete (RMC) sector by acquiring five plants in Mumbai from StarCrete. The company disclosed the purchase on 12 March 2024, with the plants having a combined capacity of 422m³/hr. The deal, valued at US$4.04m, marks a strategic expansion for Shree Cement.

Neeraj Akhoury, Managing Director of Shree Cement, said “The strategic foray into the RMC segment is a step ahead in our vision to become a multi-product company centred around a core cement business. The RMC segment is expected to witness healthy growth, driven by government initiatives in large infrastructure projects and a booming housing construction sector.”

France: Representatives from the global cement and concrete industry will meet in Paris on 7- 8 March 2024 for the Global Buildings and Climate Forum. Industry leaders will seek to set out a framework for sustainable, decarbonised buildings.

Global Cement & Concrete Association CEO Thomas Guillot said “Our industry has been leading the way on decarbonisation through the implementation of our 2050 Net Zero Concrete Roadmap, and as our Roadmap sets out we are committed to fully decarbonising this essential material.”

Bruno Pillon, Chair the French cement association France Ciment, said “France and the whole world will still need to rely on cement and concrete for future infrastructure. But it’s really important that the cement and construction sectors, governments and suppliers all work together to achieve our net zero goal.”

Chile: UNACEM has gained full ownership of precast concrete company Prefabricados Andinos. The group said that it completed the acquisition of the outstanding 50% stake in the company on 6 February 2024.

Germany/US: Concrete production equipment supplier TopWerk Group has formally endorsed Partanna Global's carbon-negative binder as a replacement for cement in the production of concrete using its equipment. Partanna plans to install TopWerk equipment at its four upcoming production plants, under an exclusive three-year agreement. The endorsement is intended to help shift TopWerk's global customers from using cement to using Partanna Global’s binder.

Partanna Global CEO Rick Fox said “TopWerk's endorsement of Partanna represents a major vote of confidence in our technology from one of the most respected names in global construction. We’re humbled and proud that one of the world’s leading concrete machinery producers has given us their backing. We hope this signals to the industry that Portland cement is no longer the only solution in town, and that the days of burning rocks are fast coming to an end.”

TopWerk CEO Robert Gruss said "We believe our exclusive partner Partanna has come up with a truly impressive solution that can contribute to putting this polluting practice to an end. The company’s carbon negative binder is one of the most exciting innovations we have witnessed in our industry for decades. It is the most advanced alternative binder solution in the market and the only credibly carbon negative solution that has the potential to scale globally. Over the last two years, we have rigorously tested their formula and have validated its application as a direct replacement solution for Portland cement. In many ways, their binder actually performs better than the legacy solution.”

The endorsement follows Saudi Arabia-based property developer ROSHN's announcement of an upcoming carbon-negative concrete plant that will use Partanna Global's technology earlier in January 2024.

Switzerland: Carbon capture and storage (CCS) equipment developer and supplier Neustark says it plans to more than double the number of its CO₂ storage sites in Austria, France, Germany, Switzerland and the UK to 34 from 14. Neustark’s process turns mineralised captured CO₂ and existing mineral waste streams into useful limestone. Building materials producers lease Neustark’s storage sites to produce reduced-CO₂ alternatives such as recycled concrete. The sites currently have a total storage capacity of 5000t. Existing customers include Holcim.

Neustark CEO Johannes Tiefenthaler said “Neustark is scaling up rapidly, and we’re well on track to achieve our aim of permanently removing 1Mt of CO₂ by 2030. Our global goal is a series of reliable, region-specific CCS facilities that can be replicated anywhere, offering immediate sustainability benefits to local supply chains.”

UK: The World Cement Association (WCA) has welcomed the introduction of the revised BS 8500 standard, which allows for a wider range of Portland limestone cement (PLC) and ground granulated blast furnace slag (GGBFS) combinations in concrete. WCA chief executive officer Ian Riley, however, described the revision as ‘not breaking new ground but catching up.’ He called on the UK and other jurisdictions to begin enacting performance-based standards.

Riley said “It is good to see BSI making this change to concrete standards, however, this is still a very modest step forward. Firstly, ground limestone has been used successfully as a cement component in many markets for decades. Secondly, in order to produce concrete with the lowest embodied carbon and the highest circularity, we need to move away from standards that require particular recipes.”

The Hunter cement plant in Texas looks set to become one of the most expensive integrated units in the world following the announcement this week that CRH is preparing to buy it for US$2.1bn. The Ireland-headquartered company said that it has agreed to acquire the plant at New Braunfels near San Antonio from Martin Marietta Material. The deal also includes four cement terminals around and near to Houston and 20 ready-mixed concrete (RMX) plants near to San Antonio and Austin. It is expected to complete in the first half of 2024 subject to regulatory approval.

Assessing the value of this deal is tricky given the various RMX plants and terminals in strategic locations. However, solely based on integrated cement production capacity, this one works out at US$1000/t given that the Hunter plant has a production capacity of 2.1Mt/yr. The value of terminals and RMX plants in the right locations cannot be overstated, but it still appears to price the cement plant dearly. CRH bought Ash Grove in 2018 for US$350/t. Five years later and the price it is paying for cement production capacity in the US has nearly tripled.

Other more recent purchases in the US include US$395/t for UNACEM’s acquisition of the Redding cement plant in California earlier in November 2023, around US$525/t for the valuation of Argos North America’s four integrated plants in September 2023, or just over US$310/t for the proposed purchase of the Redding cement plant by CalPortland from Martin Marietta Materials in March 2022. The Argos North America valuation is another awkward one given that it is part of the proposed merger between it and Summit Materials and it also includes two grinding plants, 140 ready-mix concrete plants, and a distribution network of eight maritime ports and 10 inland terminals.

In a statement, CRH’s chief executive officer Albert Manifold highlighted the usual synergy benefits but he also mentioned the expected “self-supply opportunities.” He added that the company believed that there was “significant potential to unlock additional growth opportunities across an expanded footprint in this attractive growth market.” If the acquisition completes, the company will become the largest cement producer in the state, based on integrated production capacity, at around 3.2Mt/yr. Plus, as the company pointed out in its third quarter earnings update, it also operates the Foreman cement plant in Arkansas, just across the state border to the north-east. This then gives CRH and its subsidiary Ash Grove a cement plant and/or terminals in the main population areas in Texas, namely: Houston; San Antonio and Austin; and Dallas and Fort Worth.

One reason why CRH may have gone all out for a cement plant in Texas is because it is one of the few states in the US where cement shipments have actually increased so far in 2023. Data from the United States Geological Survey (USGS) shows that shipments of Portland and blended cement fell by 2% year-on-year to just under 71Mt in January to August 2023. Yet Texas comprehensively bucked this trend with shipments rising by 10% to 8.04Mt. The only other states with this kind of growth were Maine and New York. At the start of 2023 the Portland Cement Association (PCA) predicted a 3.5% decline in cement consumption in 2023 and based on the January to August 2023 data from the USGS it isn’t far off at present.

Meanwhile, selling its cement assets in Houston and San Antonio nearly brings Martin Marietta Materials’ decade-long excursion into the sector to an end. It purchased its cement plants in Texas in 2014 when it acquired Texas Industries (TXI). Plants in California were soon sold to CalPortland but Martin Marietta Materials later picked up two more cement plants in the state when it bought the US West Region of Lehigh Hanson from Heidelberg Materials in 2021. Then, once again, the plants were sold, this time to CalPortland and UNACEM, respectively. This now leaves Martin Marietta Materials with one integrated cement plant, Midlothian, and two terminals. The size of the Midlothian plant, at 2.4Mt/yr, still gives the company a decent presence in the state.

With US cement consumption expected to bounce back to growth in 2024 and the Texas market ahead of this, CRH’s decision to buy big from Martin Marietta Materials seems like a logical move given its focus on North America. The price may seem high, but the investment seems as close to a steady bet as it gets. The day after the Texas announcement CRH revealed that it was selling its lime business in Europe to SigmaRoc for US$1.1bn. The key bit though was that these assets generated earnings of around US$137m in 2022 but, by comparison, the new units in Texas are expected to earn US$170m in 2023. This suddenly makes the price agreed for Hunter seem more reasonable. Let’s check back in a couple of years to see how well CRH’s acquisition in Texas works out. In the meantime all eyes are likely to be on what Martin Marietta Materials does next with the Midlothian plant.

Last week the US General Services Administration (GSA) announced that it was investing US$2bn on over 150 construction projects that use low-embodied carbon (LEC) materials. The funding is intended to support the use of US-manufactured low carbon asphalt, concrete, glass and steel as part of the Inflation Reduction Act. For readers who don’t know, the GSA manages federal government property and provides contracting options for government agencies. As part of this new message, it will spend US$767m on LEC concrete on federal government buildings projects following a pilot that started in May 2023. The full list of the projects can be found here.

This is relevant because the US-based ready-mixed concrete (RMX) market has been valued roughly at around US$60bn/yr. One estimate of how much the US federal government spent on concrete was around US$5bn in 2018. So the government buys a significant minority of RMX in the country, and if it starts specifying LEC products, this will affect the industry. And, at present at least, a key ingredient of all that concrete is cement.

This isn’t the first time that legislators in the US have specified LEC concrete. In 2019 Marin County in California introduced what it said was the world’s first building code that attempted to minimise carbon emissions from concrete production. It did this by setting maximum ordinary Portland cement (OPC) and embodied carbon levels and offering several ways suppliers can achieve this, including increasing the use of supplementary cementitious materials (SCM), using admixtures, optimising concrete mixtures and so on. Unlike the GSA’s approach in November 2023 though, this applies to all plain and reinforced concrete installed in the area, not just a portion of procured concrete via a government agency. Other similar regional schemes in the US include limits on embodied carbon levels in RMX in Denver, Colorado, and a reduction in the cement used in RMX in Berkeley, California. Environmental services company Tangible compiled a wider list of embodied carbon building codes in North America that can be viewed here. This grouping also includes the use of building intensity policies, whole building life cycle assessments (LCA), environmental product declarations (EPD), demolition and deconstruction directives, tax incentives and building reuse plans.

Government-backed procurement codes promoting or requiring the use of LEC building materials for infrastructure projects have been around for a while in various places. The general trend has been to start with measurement via tools such as LCAs and EPDs, move on to government procurement and then start setting embodied carbon limits for buildings. In the US the GSA’s latest pronouncement follows on from the Federal Buy Clean Initiative and from when California introduced its Buy Clean California Act in 2017. Outside of the US similar programmes have been introduced in countries including Canada, Germany, the Netherlands, Sweden and the UK. On the corporate side members of the World Economic Forum’s First Movers’ Coalition have committed to purchasing or specifying volumes of LEC cement and/or concrete by 2030. Examples of whole countries actually setting embodied carbon emissions limits for non-government buildings are rarer, but some are emerging. Both France and Sweden, for example, introduced laws in 2022 that start by analysing life-cycle emissions of buildings and will move on to setting embodied carbon limits in the late 2020s. Denmark, Finland and New Zealand are also in the process of introducing similar schemes. The next big move could be in the EU, where legislators are considering embodied carbon limits for building materials as part of its ongoing revisions to its Energy Performance of Buildings Directive or the Construction Products Regulation legislations. Lobbying, debate and arguing remains ongoing at present.

To finish, Ireland-based Ecocem spent a period in the 2010s attempting to build a slag cement grinding plant at Vallejo, Solano County, in the San Francisco Bay Area of California. The project met with considerable local opposition on environmental grounds and was eventually refused planning permission. The irony is that slag cement is one of those SCM-style cements that Marin County, also in the San Francisco Bay Area, started encouraging the use of just a few years later. Ecocem held its inaugural science symposium in Paris this week. A number of scientists who attended the event called for existing low carbon technologies to be adopted by the cement and concrete sectors as fast as possible. One such approach is to lower the clinker factor in cement through the use of products that Ecocem and other companies sell. A point to consider is, if Marin County’s code or the GSA’s recent procurement directive came earlier, then that slag plant in Vallejo might have been built. Encouraging the use of LEC building materials by governments looks set to proliferate but it may not be a straightforward process. Clear and consistent policies will be key.

South Africa: The Competition Tribunal has received a recommendation from the Competition Commission that it should allow aggregates producer Afrimat to acquire Lafarge South Africa. Creamer Engineering News has reported that the commission found that the merger involves ‘horizontal overlaps’ in the aggregates and ready-mix concrete sectors. As such, it recommended that the parties be required to divest assets across the affected sectors.
