There was fantastic news for fans of novel cements this week, when Cementos Argos announced the completion of work on a new 0.45Mt/yr calcined clay production line at its Rio Claro plant in Colombia. This artificial pozzolanic material, developed and promoted by the Swiss-led LC3 consortium in recent years, can dramatically lower cement CO₂ emissions by replacing slag and/or fly ash in cement mixes. The Rio Claro plant is the first major cement plant to install such a line following smaller trials in Switzerland, India and Cuba.

Suitable clays are more widely available than slag and fly ash, alleviating some of the difficulty and cost of obtaining supplementary cementitious materials. They also need to be calcined at just 800°C, offering massive savings in terms of fuel costs, CO₂ emissions and embodied energy compared to Ordinary Portland Cement (OPC) production. Karen Scrivener from the École Polytechnique Fédérale de Lausanne (EPFL), the leading academic party in the LC3 consortium, explained that calcined clays are at their best when in ternary (three-way) blends alongside clinker and limestone in the September 2019 issue of Global Cement Magazine. “It has long been known that calcined clays can be pozzolanic,” she explained. “When used alone, the maximum substitution level is around 30%, which gives a moderate saving in CO₂ emissions. However, if we substitute a further 15% of the clinker with limestone, we get a significant reduction in CO₂ emissions, with a product that has almost identical properties to the blend that contains just the calcined clay.”

While the exact composition of Rio Claro’s new products is unclear, it will enable Cementos Argos to produce ternary cement blends with CO₂ emissions 38% lower than OPC. Energy consumption is also cut by 30%, which provides secondary benefits in terms of reduced off-site CO₂ emissions. At the plant’s launch, Cementos Argos’ President Juan Esteban Calle clearly stated that calcined clays were the way forward, announcing, “With this project we are sowing the seeds of the Argos of the future. It starts today with a new production line at Rio Claro. In our commitment to climate change, this project makes us very proud.”

The response from Argos’ consumers will be keenly watched, especially in Europe. Just this week LafargeHolcim and Vicat, along with France’s Technical Association of the Hydraulic Binders Industry (ATILH), called on the European Commission and European Committee for Standardisation to hurry up and publish ternary cement standards across the European Union (EU). At the moment these producers are primarily concerned with CEMII / C-M and CEM VI cements. These classes of cement comprise a range of ternary blends that contain clinker and limestone, plus a third component, be it slag, fly ash, natural pozzolans or calcined clay. They claim that placing low-clinker cements on the market could reduce the amount of CO₂ emitted by 127kg/t, around 20% of the 656kg/t average in Europe at present.

Frustrated with the delays at Commission level, cement producers have now taken things into their own hands. The plan is to establish the same standard within each EU Member State at the national level, rather than waiting in vain for standards from ‘on high.’ One pressing driver for this behaviour is the rapid approach of the Phase 4 of the EU Emissions Trading Scheme (ETS) in January 2021. In Phase 4 it is likely that EU cement producers will be allocated only 80% of the free allowances they have become accustomed to. They will have to buy the remainder at market prices, currently Euro25.1/t of CO₂ (17 February 2020). This will represent a massive new expense for some producers. The opportunity to sell cement that emits only 58% of the CO₂ of OPC is clearly exceedingly attractive as a way to reduce outgoings. CO₂ emissions will be reduced, of course but, as usual, the way to make companies do things is to hit them in the wallet.

Indeed, on this point, Vicat seemed to almost goad or ‘troll’ its competitors in Europe this week by announcing that it has never sold any EU ETS allowances and is sitting atop a 5Mt CO₂ reserve worth Euro120m. This is sufficient to last it until 2030 at current prices. The key part of that last sentence is ‘current prices,’ which are subject to change. In its press release, Vicat was keen to point out that it is not resting on its laurels, highlighted by its advocacy for ternary blends and continued development of alternative fuels. This may be wise, considering that EU ETS allowances will likely cost more once Phase 4 kicks in.

With clinker factors of just 50 - 65% for CEMII / C-M, and 35 - 50% for CEM VI, Edelio Bermejo, director of research and development (R&D) at LafargeHolcim insists, "These cements are no longer at the research and development stage. They have been widely validated and we are ready to produce them, especially as their manufacture does not require modification of our facilities." The establishment of Cementos Argos’ Rio Claro calcined clay plant proves his point. We can expect to hear a lot more about these blends in the coming months. In the words of Bermejo, “The future is here!”

EU: Researchers from LafargeHolcim, Vicat and the Technical Association of the Hydraulic Binders Industry (ATILH), have called for harmonised European standards to enable the introduction of ternary cement blends such as CEM II C-M and CEM VI, which comprise clinker, limestone and supplementary cementitious materials, most commonly slag and fly ash, so that the European cement sector can lower its CO2 emissions. "It’s a very powerful short-term lever," said Fabrice Copin, director of the industrial process at ATILH.

The roadmap for achieving carbon neutrality in 2050, established by the industry in 2018, makes the development of new cements a priority. Placing low-clinker cements on the market could reduce the amount of CO2 emitted by 127kg/t, around 20% of the 656kg/t average in Europe at present.

With clinker factors of just 50-65% for CEMII / C-M, and 35-50% for CEM VI, Edelio Bermejo, director of research and development (R&D) at LafargeHolcim insists, "These cements are no longer at the R&D stage. They have been widely validated and we are ready to produce them, especially as their manufacture does not require modification of our facilities."

However, these new cements cannot be widely sold and used due to a legal deadlock at the European Commission level that hinders their approval, according to Xavier Guillot, the manager of standards coordination at LafargeHolcim. “To introduce them, the harmonised European standard which authorises their placing on the market must be revised,” said Guillot. “However, legal problems between the European Commission and the European Committee for Standardisation prevent the work from being finalised. The cement manufacturers are considering drafting a standard common to all member states, but which would be applied at a national level within each member state. We have to move forward to face the challenges we are asked to answer, namely reducing our CO2 emissions.”

One of the limits of CEM II / C-M and CEM VI cements is the availability of substitutes used to replace clinker which are clustered around other industrial sites such as steel plants and coal-fired power stations. "In the future, with an increase in the recycling of steel and possible relocations of steel mills, the deposits are likely to move away from our markets and to diminish,” said Laury Barnes, Vicat’s scientific director. “In addition, the current availability of slag will not cover all the needs for low-carbon cements. Likewise for the fly ash, which should become increasingly rare as the thermal power plants close.”

Barnes instead advocates calcined clays as a suitable replacement for slag and fly ash. "Clays are minerals found everywhere on Earth,” says Barnes, who, like Bermajo, advocates the use of LC3 cement blends being developed by a Swiss-Indian-Cuban consortium. These contain clay that has been heated to 800°C instead of slag or fly ash.

France: French press has reported that Vicat, the last remaining cement producer in French hands, has accumulated a large stockpile of EU Emissions Trading Scheme (ETS) credits, sufficient to last it until 2030. It says that this makes it unique among cement producers covered by the scheme. It has never sold any of the credits that it was over-allocated in the first three stages of the ETS. It is thought that this will put it at a competitive advantage from the start of stage 4 in January 2021, when free allowances for the sector will become significantly scarcer.

Vicat has a stock of credits that represent 5Mt of CO₂, valued at Euro120m at the current market price. "It covers our activity in France and Switzerland and we will still be in a surplus position in 2030. We are entering the next European regulatory phase in a good condition," said CEO Guy Sidos.

Vicat is keen to point out that this does not mean it is complacent or will pollute at all costs. "At the end of 2019, we reduced our CO₂ emissions by 15% compared to 1990. The objective is a further decrease of 13% between today and 2030," explained Sidos.

France: Vicat’s sales were reduced in 2019 by poor markets in Turkey and, to a lesser extent, Switzerland and Egypt. Its sales fell by 1% year-on-year to Euro2.74bn in 2019 from Euro2.58bn at constant scope and exchange rates. Its cement sales volumes dropped by 2% to 22.4Mt from 22.8Mt but its concrete volumes grew by 1.1% to 9.1Mm³ from 9.0Mm³. Its earnings before interest, taxation, depreciation and amortisation (EBITDA) decreased slightly to Euro156m.

“Strong growth in France, the US, Africa and Kazakhstan helped offset difficult market conditions in Turkey and Egypt. Furthermore, in line with our strategy of targeted acquisitions, the purchase of Ciplan in Brazil, in January 2019, allowed the group to continue its international growth in a region offering strong potential by integrating teams and assets of the highest quality,” said chairman and chief executive officer (CEO) Guy Sidos.

The group performed well in France, the US and Italy, especially due to the acquisition of Ciplan in Brazil. Sales in Turkey suffered from a generally poor economic situation. Competition in Egypt and a downturn in the precast concrete market in Switzerland caused problems in these countries respectively.

US: National Cement has broken ground on its US$250m upgrade to the Ragland plant in Alabama. City, county and state officials attended the ceremony, according to WBRC. The subsidiary of France’s Vicat is building a second kiln at its 1.9Mt/yr plant in Alabama. The project is expected to be completed in 2022.

US: Ragland Town and St. Clair County administrators have approved France-based Vicat’s US subsidiary National Cement’s plans for a second kiln at its 1.9Mt/yr Ragland cement plant in Alabama, construction of which will begin in early 2020. Birmingham Business Journal has reported that National Cement, which has had legal permission to build a second line since 2006, has announced that the new kiln will enter clinker production in 2022 following a total investment of US$250. National Cement is Ragland’s largest employer, with a staff of 132 at the 111-year-old Ragland plant.

France: Guy Sidos, the president and chief executive officer (CEO) of Vicat Group, has launched the company’s first cement carrier, Capo Cinto. The ship was acquired in partnership with ABCRM (Agency Bulk Chartering Vicat), according to Les Petites Affiches newspaper. The Capo Cinto will supply the Corsican ports of Bastia, Porto Vecchio, Ajaccio and Propiano with bulk and bagged cement, as well as Italy and the Mediterranean from the Grave de Peille integrated cement plant. French navy Vice Admiral Anne Cullerre was also in attendence at the launch.

The Capo Cinto, previously known as the Kurske, was built in 1997. The new name refers to Monté Cinto, the highest mountain in Corsica. The refitted carrier is 90.7m long, has a capacity of nearly 2000t and it has a self-unloader.

Germany: Four of Europe’s leading cement producers have partnered to found and operate a 100% carbon capture and storage (CCS) plant at Schwenk Zement’s 1.0Mt/yr Mergelstetten plant in southern Germany. HeidelbergCement has announced that the catch4climate project will enter operation in 2020.

France: Vicat has sold Euro2.06bn-worth of cement in the nine months to 30 September 2019, up by 5.7% year-on-year from Euro1.95bn in the corresponding period of 2018. Its cement section’s sales lagged behind concrete and aggregates, with a rise of 4.5% to Euro991m from Euro948m in the nine months to 30 September 2018. “The Group’s strategy of raising prices is paying off in almost all operating regions, while energy costs fell,” said Vicat Group Chairman and CEO Guy Sidos. He expects exchange rate gains to pay dividends in the final quarter, notably in Turkey.

With a good number of the financial results published by the non-Chinese multinational cement producers for the first half of 2019, it is now time for a roundup. Graphs 1 and 2 below lay some of the basics with the general sales revenue and cement production volume trends.

This is only part of the picture as the larger companies had various complications. For example, LafargeHolcim’s apparent falling revenue and sales volumes is mainly due to its massive divestments in South-East Asia. On a like-for-like basis its sales and sales volumes of cement rose. Its recurring earnings before interest, taxation, depreciation and amortisation (EBITDA) better illustrated this with a rise of 7.2% year-on-year in real-terms to Euro2.41bn in the first half of 2019 from Euro2.25bn from 2018. The company didn’t have it all its own way though with falling cement sales volumes in Asia despite the divestment and poor growth in its Middle East Africa region.

By contrast HeidelbergCement reported growing sales but its earnings and profits were down. Its profit fell by 33% to Euro291m from Euro435m. This was blamed on the group’s sale of its Ukraine subsidiary in April 2019. The operations were sold to Overin Limited, part of Ukrainian investment company Concorde Capital Group, for Euro13m. HeidelbergCement said that the divestment resulted in a loss of Euro143m. Aside from this, as Bernd Scheifele, the chairman of the managing board of HeidelbergCement, explained, positives in markets in Asia, Western and Southern Europe compensated for weaker business in North America and the Africa-Eastern Mediterranean Basin Group area.

Cemex has a tougher time of it than its larger rivals due its greater reliance on American markets. Slow starts to infrastructure projects were blamed in Mexico, poor weather hit earnings in the US and problems occurred further south too. Luckily Europe was strong for the company with lots of good news areas. It wasn’t enough though as Cemex’s sales fell by 4% to US$6.72bn from US$7bn and its operating EBITDA dropped by 11% to US$1.21bn from US$1.36bn.

As for the other companies covered in the graphs, Buzzi Unicem and Titan Group prospered due to the US market. The former described its US activity as ‘lively.’ However, it admitted that its sales growth there was mainly caused by falling imports in the face of weak domestic demand and ‘considerable production and logistical difficulties’ in June 2019 caused by flooding of the Mississippi river. Titan, meanwhile, caught a well-deserved break after recent years with growth also in Greece and Southeastern Europe. Vicat managed to stave off a decline in sales due to poor markets in Turkey, Switzerland, Indian and West Africa through its acquisition of Brazil’s Ciplan in late 2018. Yet, its earnings and cement sales volumes fell anyway.

Dangote Cement once again suffered at home in Nigeria, while its Pan Africa business grew. Trouble at home was pinned on lower volumes, price discounting, higher input and distribution costs and higher fuel and power costs in the first half of 2019. Of more concern, earnings fell in Pan Africa too in the first half due to market conditions in South Africa and Zambia. As ever though Dangote Cement’s diversity in Sub-Saharan Africa should see it through. Finally, Semen Indonesia continued to ride high as its sales increased by 23% to US$1.17bn due to its absorption of LafargeHolcim’s assets. Unsurprisingly, its sales volumes grew at a similar rate, to just below 13Mt in the first five months of 2019. Yet trouble may be store ahead as its local sales fell by 7% in this period.

Other major producers omitted here include Ireland’s CRH and India’s UltraTech Cement. Both are set to release their results later in August 2019 and will make for essential reading as the market conditions so far in 2019 become clearer. The latter in particular will be worth watching if a report by Indian credit agency CARE Ratings out this week is correct. It has forecast production capacity growth of 120Mt by 2030 in India. UltraTech Cement is perfectly poised to benefit from this.
