Ternary cements – The future is now!
19 February 2020There 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.

17 February 2020Morocco: Bedeschi has reported that erection works are underway at a project it is carrying out for LafargeHolcim in Morocco. Following an intense civil work phase, during which the single trusses were preassembled and equipped with the mechanical comports, the 4.3km-long belt conveyor is taking shape. The site team is taking full advantage of Trimble Connect to facilitate the erection works.
The conveyor, which trusses up to 5t completely assembled at ground, has been erected on a mountain using a suspended cableway. The system, installed and operated by Bedeschi team with its partner SEIK, allowed fast-track operations with high degree of safety and quality.
LafargeHolcim España Euro8m upgrade to Sagunto cement plant dependent on quarry talks
14 February 2020Spain: LafargeHolcim España says that a planned Euro8m investment to its Sagunto integrated cement plant is dependent on talks with the Valencian local government on the medium and long-term use of its quarry. Plant director José Luis Coleto said that this expenditure is part of a Euro20m package that LafargeHolcim has scheduled for the country until 2022. He added that the plant has spent Euro3.5m on the plant in 2019 on control systems upgrades and installation of an automated laboratory.
Siame Kaulule leaves Lafarge Zimbabwe
12 February 2020Zimbabwe: Lafarge Zimbabwe’s chief executive officer (CEO) Siame Kaulule has left the company for a new role with LafargeHolcim in South Africa, according to the NewsDay newspaper. Kaulule was appointed as the head of LafargeHolcim’s Zimbabwe operations in early 2019. He succeeded Amal Naiel, who spent five years in the post.
A reordered South African cement industry?
05 February 2020There have been rumours in the press this week that LafargeHolcim is weighing up its options in South Africa. Reports in the local press allege that the building materials company has tasked Credit Suisse Group with finding a buyer for its business. This may or may not be true, only time will tell, but South Africa certainly feels like a market where LafargeHolcim should be considering its future.
As a prominent but smaller producer in the country, Lafarge South Africa is behind PPC and AfriSam in terms of clinker production capacity. InterCement’s subsidiary Natal Portland Cement and Dangote’s subsidiary Sephaku Cement have a similar production base with an integrated plant each and one or two grinding plants. Halfway through 2019 LafargeHolcim was describing market conditions as ‘difficult’ in the country with it being the sole Sub-Saharan market holding back regional growth for the group. By the third quarter the situation had reportedly improved but net sales and cement sales volumes were flat for the year to date. A clearer picture should emerge when LafargeHolcim publishes its fourth quarter results at the end of February 2020.
PPC provided its view of the market in its half-year results to 30 September 2019. Its estimate was that the South African cement industry declined by 10 - 15% for the period, creating a competitive environment. It added that the situation had been, ‘exacerbated by imports and blender activity.’ Both its revenue and earnings fell year-on-year, although a 30% rise in fuel costs didn’t help either. Sephaku Cement suffered a similar time of it, with a 19% fall in cement sales volumes during the first half, although it reported improvement in the subsequent quarter. Overall, it blamed falling infrastructure investment for pressurising the market and allowing blending activity to mount. Sephaku Cement was also wary of the local carbon tax that started in June 2019 warning of a potential US$2.8m/yr bill.
PPC noted that cement imports had risen by 5% to 0.85Mt in the year to August 2019. This followed a lobbying effort by The Concrete Institute (TCI) in mid-2019 to implore the International Trade Administration Commission (ITAC) to look into rising imports levels. At the time the TCI’s managing director Brian Perrie expressed incomprehension that a country with six different cement production companies with an over-capacity rate of 30% could be facing this problem. This latest broadside tails South Africa’s previous attempt to fend off imports when it instituted anti-dumping duties of 17 – 70% against importers from Pakistan in 2015. Imports duly fell in 2016 but rose again in 2017 and 2018, mainly from Vietnam and China.
All of this sounds familiar following LafargeHolcim’s departure from the ‘hyper-competitive’ South-East Asian countries in 2019. Those countries also suffered from competition and raging imports. Bloomberg pointed out in a report on the local industry in 2016 that PPC’s, AfriSam’s and LafargeHolcim’s kilns had an average age of 32 years, suggesting that efficiency and maintenance were going to be concerns in the future. Also of note is LargeHolcim’s decision to move its South African operations from one subsidiary, Lafarge Africa, to another, Caricement, in mid-2019.
Some level of market consolidation would certainly help local overcapacity. Plus, surely, LafargeHolcim’s mix of inland integrated capacity and a grinding plant near the coast could prove enticing to some of the Asian companies pumping out all of those imports. The thought on the minds of potential buyers everywhere must be, if LafargeHolcim chief Jan Jenisch was bold enough to sell up in South-East Asia, how can he not in South Africa?!”
Philippines: Samuel O Manlosa has been appointed as the manager of Holcim Philippines’ Davao plant. He succeeded Xavier Arul Kennedy Savarimuthu in the post, who has been reassigned by the LafargeHolcim Group to lead plant operations in Nigeria.
Previously, Manlosa led a project to improve systems and processes to yield efficiency gains for Holcim Philippines' manufacturing operations. He has worked as a process and automation expert for LafargeHolcim's operations in Southeast Asia supporting plants in seven countries. Manlosa has also been sent to Holcim Switzerland for training on advanced process engineering and cement manufacturing. A native of Dipolog City, Zamboanga del Norte, he is a graduate from the Mindanao State University in Marawi City.
LafargeHolcim signed an agreement with San Miguel Corporation in mid-2019 for the divestment of its entire 85.7% shareholding in Holcim Philippines. The process is still ongoing.
Canada: Tina Larson has been appointed as Vice President, Saskatchewan and Manitoba by Lafarge Canada. She first joined Lafarge in 2010 as General Manager, Pipe in the Greater Calgary Area following a 16-year career with Weyerhaeuser Canada where she held various management positions. In 2015, Tina was promoted to the country level role of Director, Health and Safety for Western Canada. Larson holds an undergraduate and graduate degree in Chemical Engineering from the University of Alberta.
LafargeHolcim opens Global Hub in India
05 February 2020India: Switzerland-based LafargeHolcim has co-located its global digital and business services at a single site in Mumbai. The company says that the Global Hub will enable it to ‘focus on providing modern global platforms and capabilities, accelerating the pace of innovation at a local, regional and global level.’
LafargeHolcim rumoured to be offloading South African assets
04 February 2020South Africa: LafargeHolcim is planning to sell its South African operations as the world's largest building material maker continues to streamline its portfolio, according to sources close to a deal who spoke to Bloomberg. The Swiss company is working with adviser Credit Suisse Group to seek a buyer for the business. It has apparently already reached out to local competitors, Chinese cement producers and buyout firms, but may struggle to attract interest for the unit due to challenging dynamics in the country's cement industry. South Africa is Africa’s most mature cement market but it is hampered by decreasing demand, old production facilities, tight domestic competition and cheap imports from the Middle East. A representative for LafargeHolcim declined to comment.
