Global: Global Cement and Concrete Association (GCCA) has launched the Innovandi Open Challenge 2025, inviting start-ups to wok together with cement manufacturers around the world in developing low carbon concrete technologies.

The Open Challenge is looking for start-ups working on next generation materials for net zero concrete, including low-carbon admixtures, supplementary cementitious materials, activators or binders. The challenge aims to find ways to reduce clinker use and incorporate new materials to lower CO₂ emissions.

The programme follows three previous Open Challenges.

Chief executive Thomas Guillot said "Advanced production methods which are decarbonising our sector are already being used in cement and concrete production in many parts of the world. Through the Innovandi Open Challenge, start-ups can bring in even newer ideas and further accelerate our industry's push."

“If you are a start-up from anywhere in the world with an innovative idea or technology, then we want to hear from you."

Start-ups can find more information and apply to take part in the Innovandi Open Challenge by going to the GCCA Open Challenge 4 webpage: Innovandi Open Challenge 4 : GCCA

Saint-Gobain looks set to increase its presence in the construction chemicals market this week when it announced a deal to buy Fosroc. A definitive agreement has been set for the acquisition valued at just over US$1bn. The purchase will be financed in cash and is expected to close in the first half of 2025.

The light construction materials company has been growing its construction chemicals capabilities for several years now. In 2021 it acquired Chryso for Euro1.02bn and then it bought GCP Applied Technologies for Euro2.3bn in 2022. Acquisitions of smaller companies in the sector, including Duraziv and IMPAC, also took place. With regards to the proposed Fosroc transaction, Saint-Gobain highlighted in its press release that the deal was “supported by solid macroeconomic factors including the transition towards low-carbon concrete.” It also noted that Fosroc’s geographic profile would strengthen its own presence in emerging markets such as India and the Middle East. Chryso’s market share is mainly in Europe, Turkey and Africa. GCP’s is in North America, Latin America and Asia-Pacific.

As Riccardo Stoppa, Saint-Gobain’s Business Director of Cement additives related to Global Cement Magazine in our May 2024 issue, the Construction Chemicals Business Unit of Saint-Gobain’s High Performance Solutions (SGHS) division broadly produces two groups of products for the cement and concrete sector: additives and admixtures; and a wider range of more recent products using newer chemistry approaches. Saint-Gobain’s total annual revenue is around €48bn/yr with SGCC’s contribution weighing in at around €1bn/yr. Most of that latter revenue derives from the former businesses of Chryso and GCP. Finally, Stoppa highlighted SGCC’s strength in North America, Europe and China but also highlighted the potential in the Middle East for its products. That last point makes interesting reading in light of the current Fosroc deal.

India was flagged as a benefit of the proposed Fosroc purchase. If any further reminder of the growth and market consolidation taking place there were needed, UltraTech Cement revealed this week that it is in the process of buying a 23% share of The India Cements. This story ties into the rivalry between the country’s two largest cement companies. Both UltraTech Cement and Adani Group are mounting up production capacity at pace through both acquisitions and by building new plants. All of this is rosy news for a company selling additives and admixtures to the cement and concrete market.

Saint-Gobain latest acquisition is subject to the usual regulatory conditions as one might expect. Yet, what Saint-Gobain didn’t mention in its statement, was that it reportedly had one of its sites in Türkiye visited in late 2023 as part of an international investigation into anti-competitive behaviour in the sector. Switzerland-based Sika was also linked to the case at the time. The UK-based Competition and Markets Authority (CMA) announced in October 2023 that it had launched an investigation into suspected anti-competitive conduct in relation to the supply of chemicals for use in the construction industry. It said it was working with the European Commission and that it had been in contact with other authorities, including the US Department of Justice, Antitrust Division. At this time Sika confirmed to Construction News that inspections had taken place into “suspected antitrust irregularities in the area of additives for concrete and cement.” However, it is important to note here that these were merely information gathering activities and no accusations of any breaches of competition law have been made so far. All of this suggests that Saint-Gobain does not seem too troubled by the interest of the various competition bodies with regards to its expansion plans.

In his interview, Stoppa told Global Cement Magazine that SGCC’s products allow cement and concrete producers to reduce the amount of cement used in their concrete. This is almost heretical thinking to a world that produces too much clinker. Yet Saint-Gobain is betting on exactly this outcome through the expansion of its construction chemicals division. Its purchase of Fosroc is the latest stage in this line of thought. It’s not the only company doing this. In May 2023 Sika completed its purchase of MBCC Group, another admixture manufacturer. Further sector consolidation looks likely.

India: Ramco Cements has commissioned a 3000t/day integrated cement line at its Ramamasamy Raja Nagar cement plant in Tamil Nadu. Projects Today News has reported that the plant runs on renewable energy from a captive wind farm, and recycles 90% of water used in production.

Ramco Cements produces Ramco 53 Infra Super cement at the Ramamasamy Raja Nagar plant. The product allows for lower cement and admixture content to be used in the production of concrete structures.

More mergers and acquisition news emerged this week in the shape of potential buyers for Sika’s US admixtures business. Reporting from Bloomberg revealed that Holcim, HeidelbergCement and Turkey-based Sabancı Holding had all made it, amongst other unnamed companies, to a second round of bidding for the assets. Sika then confirmed this to the Finanz und Wirtschaft newspaper and added that the sale would also relate to Canadian assets as well. The intention here is to bypass the risk of a lengthy competition investigation in the US.

Switzerland-based Sika announced in November 2021 that it had signed a deal to buy MBCC Group from Lone Star Funds, a global private equity firm, for Euro5.2bn. At the time of the announcement Sika said that the transaction was subject to regulatory approval but it added that it was ‘confident’ that all required clearances would be obtained with closure planned for the second half of 2022. Known competition probes are now pending in the UK, Australia and New Zealand. A previous piece from Bloomberg suggested that internal analysis by Sika found that the company might need to divest operations with annual sales of around US$160m with a value of US$400m. However, the latest update suggests a value of up to US$1bn. The US represented US$1.71bn or 18% of Sika’s total group sales in 2021. Sika’s information to shareholders to let them know about the MBCC acquisition in November 2021, showed that MBCC had sales of around US$966m in the Americas in 2021 with 36 production plants. Overall, not just in the US, the deal is expected to change Sika’s technology mix from 40% concrete and cement systems to 49%, with most of the additions coming from concrete applications.

Divestments were always likely in an acquisition this large between competitors with shared geographies. What is interesting here to the cement sector is that the three named interested parties are all cement producers. Holcim is perhaps the least surprising given its size, pivot towards light building materials and the fact that its current head, Jan Jenisch, used to run Sika. If anyone knows how much an admixture company is worth, it’s the guy who ran one five years ago! HeidelbergCement does not have such a large light building materials business footprint but it is demonstrably interested in making heavy building material production more sustainable. Also, as the world’s second largest western multinational cement producer it is likely to be interested in an input market for some of its end products. Sabancı Holding is the outlier in this grouping with a more regional grey cement business based in Turkey, an international white cement business and a diverse set of business interests including finance and energy. Although, even as the smallest of the bunch, it still reported sales revenue of over US$9bn in 2021. One notable absence from the potential contenders list for Sika USA is Cemex. Its Urbanisation Solutions division, which produces admixtures among other products, reported sales of US$1.9bn in 2021 or 13% of the group’s total revenue. US$558m of this was made in the US.

The wider context in the North American admixture market is that the announcement of Sika’s deal with MBCC in November 2021 was followed about a month later when Saint-Gobain said it had entered into a deal to buy GCP Applied Technologies. This followed Saint-Gobain’s acquisition of Chryso in October 2021. However, Saint-Gobain said that the GCP deal would strengthen its position more in North America. Readers can find out more about Saint-Gobain’s ambitions here.

The final word at this stage should go on Lone Star Funds, the current owner of MBCC. Lone Star Funds bought the construction chemicals business from BASF for Euro3.17bn in September 2020. At the time the acquisition closed Saori Dubourg, a member of the board of executive directors of BASF, said “Lone Star has been a professional partner in this transaction and is committed to the future success of the business.” If the reporting is correct, Lone Star Funds is now selling the same business for over Euro5bn. There are two takeaways to consider at this point. One is that the perceived value of products that make cement and concrete more sustainable are growing. The other is that Lone Star Funds timed its acquisition of MBCC from BASF very well.

US: Bloomberg has named Germany-based HeidelbergCement, Switzerland-based Holcim and Turkey-based Sabancı Holding as possible bidders for some of Sika’s US admixtures assets. Sika is seeking to divest the assets in order to obtain competition authorities’ approval for its US$6bn acquisition of Germany-based construction chemicals company MBCC from Lone Star Funds.

UK: Concrete admixture producer Oscrete UK has appointed Matthew Gabriel to the role of new product development and sustainability manager. The company says that the appointment strengthens its commitment to sustainable construction.

Gabriel said “With the environment at the forefront of everyone’s minds, and customers looking to increase their use of supplementary cementitious materials (SCM), my priority is to develop products and processes which support our customers’ own route towards low carbon concrete.” He continued “Finding cost effective green solutions without impacting performance is key to the future of the construction sector. We are now looking to develop products that can help our customers to use or increase the use of products with a lower eCO₂, hence the creation of a role dedicated entirely to this arena.”

Germany: Master Builders Solutions has announced the addition of a new range of admixtures consisting of MasterEase and Master X-Seed to its admixtures portfolio. The company developed MasterEase and Master X-Seed to best enable European cement companies to produce cement of the EU’s new CEM II/C-M and CEM VI Portland-composite cements. Master Builders Solutions hopes that the new products will drive the construction industry’s transition to low-clinker cements and CO2-optimised concrete.

Parent company MBCC Group’s European president Christian Geierhaas said “Providing sustainable solutions is a key factor of Master Builders Solutions’ portfolio and overall strategy. Strong partnerships are essential and support and accelerate the development of significant innovations. We work with major players to continuously develop efficient admixtures to add value to our customers and achieve a long-term sustainable positive effect on the construction industry.” He added “In addition to the usual performance criteria, such as fluidity and compressive strength, our new solutions for our ready-mix customers are characterised by their outstanding robustness. Our admixtures provide an important differentiator by guaranteeing consistently high quality concrete, even upon variation of the cement type and fluctuation of the raw materials used to produce these new, more sustainable cements.”

UK: Concrete admixture manufacturer Oscrete UK has become standalone company following its departure from Christeyns Group. The move is intended to spark a period of investment and allow for a renewed focus on core markets. Oscrete manufactures and supplies a range of super-plasticising admixtures,waterproofing agents and efflorescence controllers for the precast and ready-mix concrete and the ready-to-use mortar industries. It has operated within Christeyns Group since 1983.

Scott Wilson, director of Oscrete UK, said, “The pandemic brought considerable challenges in the construction sector, quickly followed by substantial growth and we’ve recognised we need a bespoke business model dedicated entirely to our industry to facilitate growth, new product development within our in-house development lab and specialist recruitment.

Mexico/Denmark: Cemex and 3D printing construction company Cobod International have launched D.fab, a range of admixtures which enable builders to use ordinary concrete in 3D printing. The partners say that the products eliminate the need for expensive specialised mortars. Power2Build implemented the admixtures in concrete to print a whole house in Luanda, Angola, in early December 2021.

Cemex’s executive vice president sustainability, commercial and operations development Juan Romero said “The introduction of this revolutionary 3D printing system is a testament to our customer-centric mindset and relentless focus on continuous innovation and improvement. Working together with Cobod, we have developed an experience for customers that is superior to anything that has been provided in the past,” said “Our innovation efforts position us at the forefront of new technologies that contribute to building a better future.”

Saint-Gobain has headed back to the attention of the cement sector this week with a deal to buy GCP Applied Technologies and a joint-venture with Cementos Argos in Colombia.

The first development carries on the French conglomerate’s move into the construction chemicals market. In October 2021 it acquired Chryso for Euro1.02bn. Other recent deals include agreements to buy Romania-based construction chemicals company Duraziv in May 2021 and Mexico-based IMPAC in October 2021. The GCP Applied Technologies deal is valued at Euro2.3bn with closure planned by the end of 2022. As Saint-Gobain put it, “The combined platform of Weber, Chryso and GCP offers customers a highly comprehensive portfolio of construction chemicals solutions with strong complementary geographic footprints.” It says that it sees the planned acquisition as the “logical next step” to expand its market share in admixtures and additives. It also reckons that Chryso and GCP Applied Technologies are complimentary geographically with Chryso positions mostly in Europe, Middle East and Africa and with GCP’s positions in North America, Asia-Pacific and Latin America. Once the deal goes through, Saint-Gobain will operate 75 production sites in the sector in 38 countries. The specialty building materials part of GCP will then be integrated into the CertainTeed subsidiary in North America.

The arrangement in Colombia concerns a joint-venture intended to focus on lightweight and sustainable building materials. Detail is scarce beyond an announcement by Cementos Argos on its website but the focus appears to be on bringing in Saint-Gobain’s mortar products and/or technology into the local market.

This move towards the lightweight building materials market may sound familiar. That’s because it is similar to what Holcim has also been doing recently, notably with its acquisition of Firestone Building Products earlier this year. It is interesting though to see both companies targeting the lightweight sector from different places. Both have also framed their intentions in terms of sustainability goals. Notably, Saint-Gobain has far lower carbon emissions than many cement producers. For example, Holcim reported sales of around Euro22bn in 2020 with absolute gross Scope 1 CO₂ emissions of 110Mt. Saint-Gobain reported sales of around Euro38bn with total Scope 1 CO₂ emissions of 7.9Mt.

At an investors event in October 2021 Saint-Gobain’s chief executive officer Benoit Bazin said that the group’s ambition was to become the worldwide leader in light and sustainable construction. Saint-Gobain’s business portfolio was diverse already before the GCP announcement, with its construction products focused on ‘lighter’ materials such as gypsum wallboard, insulation and glass. Its expansion into the construction chemicals market is of relevance to the cement industry directly through the supply of admixtures for cement and concrete. It’s also of interest to wider trends in construction because the acquisitions show another company chasing the lightweight building materials market. One expectation, as countries and companies have signed up to net zero carbon commitments, is that the demand for lightweight materials in the building envelope will grow and companies are reacting accordingly. The question at this stage is whether there is space in their growing market for all of them.
