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.

Adani Group’s subsidiary Ambuja Cements signed a deal this week to buy Penna Cement for US$1.25bn. The agreement adds 14Mt/yr of cement production capacity to the group with a focus in the south of India. The acquisition is a big step towards the group’s target of reaching a capacity of 140Mt/yr by 2028. Ajay Kapur, the head of Ambuja Cements, also singled out the advantage the company hopes to gain from taking control of Penna Cement’s terminals saying that they would “prove to be a gamechanger by giving access to the eastern and southern parts of peninsular India.” The move is expected to increase the group’s market share in India by 2%, and by 8% in South India.

Penna Cement operates four integrated plants in Andhra Pradesh and Telangana with a capacity of 7Mt/yr. Two of these units also include waste heat recovery installations and one has a captive power plant. It runs two grinding plants in Andhra Pradesh and Maharashtra with a capacity of 3Mt/yr. Another integrated plant is being built at Jodhpur in Rajasthan and a grinding plant at Krishnapatnam in Andhra Pradesh. Finally, the company owns four bulk cement terminals at Kolkata, Gopalpur, Karaikal and Kochi in India, one at Colombo in Sri Lanka and it also owns a 25,000t cement carrier.

Adani Group’s march towards that target of 140Mt/yr by 2028 started off in mid-2022 when it purchased Ambuja Cements and ACC from Holcim. This gave it a starting capacity of 68Mt/yr in the cement sector. Various smaller additions followed including new plants at Ametha and Dahej and the acquisitions of Asian Cement and Concrete, MyHome Industries and Sanghi Industries. The latter company was the biggest of these purchases. Once the in-progress projects from Penna Cement are built, Adani Group should have a capacity of 93Mt/yr. Another 20Mt/yr is reportedly at various stages of execution. The remaining 27Mt/yr is described as being ‘blueprint ready.’

Generally, the local financial press has been in favour of the transaction agreeing with the geographic advantages of Adani Group increasing its presence in the southern states. The benefits of the high number of railway sidings at Penna Cement’s plants were also commented upon as a means for Ambuja Cements to reduce its costs per tonne of cement. The logistics benefit from the port terminals is also expected by Adani Group’s chief financial officer to reduce the group’s logistics costs with an impact expected within the next year. However, it has been reported that Penna Cement’s operating performance had been weaker in the last financial year due to low sales volumes, poor operational efficiency and high coal costs. A takeover by Adani Group could certainly fix the latter two issues. Yet, it has also been reported that competition in the cement markets in Andhra Pradesh and Telangana is up, due to a mismatch between supply and demand. So, improving Penna Cement’s capacity utilisation in these regions might be harder to solve than simply being absorbed into Adani Group.

India’s two largest cement producers both have plans in motion to mount up production capacity by the end of the decade in what has been dubbed ‘the battle of the billionaires.’ The market leader is UltraTech Cement and it has shown reluctance to cede ground to the cement newcomer Adani Group. The former company’s current target is to make it to just under 190Mt/yr by 2027. It said it had a capacity of 152Mt/yr in May 2024. It is ahead of Adani Group by this measure but there is still plenty of scope for surprises. Given the rivalry between the companies there is a regular stream of speculation about which of the smaller cement producers they might be about to buy at any given time. For example, in October 2023 HeidelbergCement India was rumoured to be courting offers from UltraTech Cement, Adani Group and JSW Cement. Last week, Adani Group was reportedly interested in buying either Saurashtra Cement, the cement business of Jaiprakash Associates, Vadraj Cement or… Penna Cement. Occasionally the rumours are true after all. UltraTech Cement remains in first place for now but the situation may change.

The Hillhead Quarrying, Construction and Recycling Show is in full flow this week, taking place near Buxton in Derbyshire. As one delegate marvelled on the panoramic minibus journey down to the quarry, “It’s like a music festival without the music and… other stuff.” Indeed. Of course what one doesn’t find at Glastonbury and the like is a near comprehensive range of suppliers, over 600 of them, to the industry all in one place… in a quarry! Where else can one get up close and see the new hydrogen-powered generators and excavating vehicles that are being piloted? The official attendance figures don’t get released until after the event but on the ground it looks as busy as ever. It’s truly the place to be this week.

The show gives us a reason to take a look at the UK cement sector. Like many other countries around the world it is an election year in the UK, with a General Election scheduled for 4 July 2024. The result of this should determine the next Prime Minister and the ruling party. So, naturally, the MPA, the trade association for the aggregates, asphalt, cement, concrete, dimension stone, lime, mortar and industrial sand industries, is taking the opportunity to remind the political parties what its priorities are. The quick version is: support for decarbonisation; a streamlined planning system; and better delivery of projects. This sounds familiar to priorities in other countries but one British spin on this includes the UK’s carbon border adjustment mechanism (CBAM).

Edwin Trout’s feature on the UK cement sector in the June 2024 issue of Global Cement Magazine presents a good overview of the last 12 months. The general UK economy has faced shocks in recent years such as Brexit, Covid-19 and the war in Ukraine. However, this has been further compounded by a downturn and high interest rates since late 2022 when the then Prime Minister Liz Truss caused market turbulence in the wake of a badly received government financial statement. As Trout relates, sales of heavy building materials have been in relative decline since mid-2022 with more of the same expected in 2024. Production of cement in 2023 is currently uncertain given the reporting time lag from the MPA but up until 2022 domestic cement sales fell somewhat but imports grew. This has created a situation where overall cement sales in 2022 were 12Mt, not far behind the annual level in the early 2000s. However, the share of imports has nearly doubled since then. More recent MPA data on mortar and ready-mixed concrete sales throughout the first nine months of 2023 suggest that market activity has decreased and poor weather at the start of 2024 looks set to have made this worse.

Despite the apparent slowdown in building materials sales the cement companies have been conducting smaller-scale maintenance and upgrade projects at their facilities and supply chain schemes such as the cement storage unit for deep sea shipping lines that Aggregate Industries said in February 2024 it was going to build at the Port of Southampton. The news the cement companies want to show off has been a steady stream of information about ongoing decarbonisation projects in the cement sector. C-Capture started a carbon capture trial at Heidelberg Materials’ Ketton cement works in Rutland in May 2024, Capsol Technologies said in March 2024 that it had been selected to conduct a study on its carbon capture technology at Aggregate Industries Cauldon cement plant in Staffordshire, Heidelberg Materials' Ribblesdale cement plant in Lancashire announced in March 2024 that it was taking part in a study to assess the use of ammonia as a hydrogen source for fuelling cement kilns and Heidelberg Materials awarded Japan-based Mitsubishi Heavy Industries (MHI) a front end engineering design contract for a carbon capture installation at its Padeswood cement plant in Flintshire in February 2024. Finally, on the divestment front, CRH completed the sale of its UK-based lime business to SigmaRoc for €155m in March 2024. The business operates from sites in Tunstead and Hindlow with five permitted lime kilns.

That’s it for this short recap on the UK for now. For a longer look at the UK cement sector read Edwin Trout’s feature in June 2024 issue of Global Cement Magazine.

Hillhead 2024 runs until 27 June 2024

The National Development and Reform Commission and other government bodies in China released plans this week to cap clinker production capacity at 1.8Bnt/yr by the end of 2025. Energy efficiency of existing capacity will be used as the driver to determine which production lines can remain open. 30% of capacity will be required to be above the benchmark energy efficiency level. Plants below this line will be obliged to upgrade or face elimination.

Points of interest from the longer release include detail on how the authorities intend to promote energy efficiency. Installing improved production line equipment is as might be expected. However, there is also a drive towards low-carbon fuel substitution such as an increased thermal substitution rate (TSR) through the use of alternative fuels (AF), promotion of renewable energy sources and, interestingly, no new cement plants will be able to add captive coal power plants. The government is targeting a TSR of 10% by the end of 2025 with 30% of lines using AF in some form or another. A plan to reduce the clinker factor in cement is also being pushed through for the increased use of blast furnace slag, fly ash, carbide slag, manganese slag and other supplementary cementitious materials. This last point might have big implications for the ferrous slag export market but that’s a story for another day.

Working out how much these new measures will affect the cement sector in China in the short term is not straightforward since it’s unclear what the country’s actual production capacity is and how much of it is actually active. Data from the National Bureau of Statistics of China showed that cement output was 2.02Bnt in 2023. The China Cement Association (CCA) estimated that the capacity utilisation rate was 59% in 2023. So, if the sector were using all of its integrated cement plants flat out, then one might crudely suppose that the national production capacity might be around 3.5Bnt/yr. This guess does not take into account the prevalence of blended cements and a whole host of other factors so should be treated with caution. Given that cement output fell by 5% year-on-year in 2023, output could be just over 1.8Bnt in 2025 if the rate of decline holds. Research by Reuters in April 2024, suggested that the capacity utilisation rate hit 50% in that month, suggesting that the sector could meet the target in 2024 if it’s a particularly bad year. So, provided the production cap is enacted along the same lines of peak-shifting, where plants are temporarily shut for periods, then the target looks well within reach.

As reported in April 2024, the Chinese cement sector has faced rationalisation in recent years as the real estate market collapsed. Output peaked in 2020 and then fell subsequently. Most of the big producers endured falling sales volumes, revenue and profit in 2022, although some managed to resist the continuing decline in 2023. One coping mechanism has been to focus on overseas markets as proposed by the government’s Belt and Road initiative. Huaxin Cement has been a particular proponent of this strategy. The CCA says that China-based companies have invested in and built 43 clinker production lines in 21 countries with a cement production capacity of 81Mt/yr. Another 43Mt/yr of capacity is currently being built outside of China with yet another 25Mt/yr of capacity proposed for construction.

It is interesting, then, to note that the CCA issued an official warning this week to its members to invest ‘cautiously’ in Uzbekistan. The association said in a statement that at the end of April 2024 the country had 46 integrated production lines with a cement production capacity of 38Mt/yr. This is double the country’s demand for cement. Half of this production capacity is managed by China-based companies. It added that the utilisation rate was currently 50%, that the price had dropped by about 40% since 2020 and that competition was ‘fierce.’ Incredibly, another 7Mt/yr of capacity is expected to be added in 2024. The CCA has advised Chinese companies to consider the state of the Uzbek cement market before making any more investments.

The two news stories we have explored this week cover two sides of the same issue: Chinese cement overcapacity. The local market is finally slowing down after a period of phenomenal growth and the big question is what is the actual market demand now that all the big stuff has already been built. The government gives every impression it is using the decline to meet its sustainability goals. Like institutions in many other places it has set itself targets that it seems likely to meet. The flipside of overcapacity at home is investment overseas. China-based plant equipment manufacturers have certainly done well out of this situation. Yet in Uzbekistan, at least, it looks like the cement sector in China has also managed to export its overcapacity. This has created the absurd situation where the CCA has implored its members and others to exercise the same self-discipline abroad that the government extols at home. Another way to put this might be that Chinese cement companies are increasingly unable to make money at home… or in Uzbekistan. This then leaves a query over where else enthusiastic Chinese cement investors may be causing market imbalances. One solution might be for the Chinese government to impose a cap on clinker production by its companies outside the mainland. Whatever happens next though, the introduction of a capacity cap in mainland China marks a decisive change to the local cement sector.
