US: Charah Solutions has installed its MP618 thermal beneficiation technology at its terminal in Sulphur, Louisiana. The upgrade is intended to improve the quality of fly ash and to increase its supply of marketable fly ash to concrete producers. The proprietary process reduces loss on ignition, ammonia, activated carbon and moisture in fly ash.

The company hopes to provides concrete product producers and builders with a source of Class F fly ash to support a growing number of construction projects in the greater Lake Charles and Sulphur region. The Sulphur terminal is Charah Solutions’ second barge-supplied location in southern Louisiana. Its LaPlace, Louisiana terminal currently serves customers in Louisiana, Mississippi and Alabama.

US: Aggregate Industries, a US subsidiary of LafargeHolcim, has secured the contract to provide concrete for the US$2bn Minneapolis-area Southwest Light Rail Transit (LRT) extension of the Metro Green Line. The new line will run 14.5 miles from downtown Minneapolis to the suburb of Eden Prairie, Minnesota, and require construction of 16 new stations, plus the rail infrastructure itself. The project will require an estimated 0.30Mm³ of ready-mix concrete. It includes the construction of 44 structures, 29 new bridges, two cut and cover tunnels, six pedestrian tunnels, 15 at-grade crossings, 110 retaining walls and over 45,000m of track.

Fascinating information came out of LafargeHolcim last week as part of its Capital Markets Day 2018. The building materials company said it is expecting sales growth to slow in 2019 but earnings to grow. Jan Jenisch, the chief executive officer (CEO), said that the group was ‘aggressively’ moving forward in aggregates and ready-mix concrete. Alongside this, its recent divestment of its Indonesian operations was declared a ‘major’ milestone in focusing its portfolio and cutting down on debt.

Graph 1, above, gives a good idea of how LafargeHolcim has been changing its business. Cement sales as a percentage of total sales have been cut to 60% in 2017 from 67% in 2015. Ready-mix concrete and other sales (including asphalt) have risen to 26% from 19%. Aggregate sales have stayed at around 14%. If the world is making too much cement then LafargeHolcim is switching to concrete and balancing out its supply chain. Naturally, this was backed up in one of its investor presentations showing a more even split in the world building materials market between cement, concrete and aggregates. This fits with Jenisch’s background as the former head of Sika. That company manufactures a wide range of specialty chemicals for the construction and automotive industries.

That shift in focus could also be seen at the inaugural Global Cement and Concrete Association (GCCA) event in late November 2018 where concrete was very much the centre of attention from a sustainability angle. The main companies involved with the GCCA are vertically integrated ones and, by switching its product balance, LafargeHolcim seems to be moving in the same direction. In a sense this is a continuation of the synergy-seeking that was promised when Lafarge and Holcim merged in 2015.

The other interesting question for LafargeHolcim is where next for growth? The graphic above shows a number of promising areas, including India and east Sub-Saharan Africa. Also, note the slowdown forecast for China. That renewed faith in India is timely this week given the expectation by the Indian Cement Manufacturers Association that cement demand growth in the country will rise by at least 10% in the current financial year to March 2019. If the momentum holds up after a strong first half then it will mark the fastest increase for the region since the market slowed down in 2011. LafargeHolcim doesn’t appear to be on course to grow significantly in India anytime soon but it has major ‘skin in the game’ in a promising market.

Another indication of the vibrancy of the Indian market also came this week from the Cement Sustainability Initiative (CSI) with the results of a status review from its low carbon technology roadmap (LCTR). The results were fairly good for such a large industry, with falling CO₂ emissions intensity, growing co-processing rates and a decreasing clinker factor. This report carried a sad note given that the work that the CSI does will be taken over by the GCCA in January 2019. However, if this is the last we’re going to hear from the CSI, then they’ve left on a high note.

Lastly, leafing through old financial reports may not be everybody’s idea of a good time but it does let one see how LafargeHolcim’s product mix has changed. It also gives one time to catch up with old faces. Like Bruno Lafont and Eric Olsen. Once again those two former executives popped up in the latest twist of the on going Lafarge Syria legal case as a group of Yazidi women have applied to become ‘civil parties’ in the case. Whether the war crimes inflicted upon the Yazidis can be pinned on Lafarge Syria remains to be seen. Yet, for all of the LafargeHolcim’s business reorganisation, its predecessor’s conduct in Syria continues to make headlines. However much progress the company makes in turning around its fortunes, if it can be, this will continue to overshadow everything. Once a line is drawn under the affair then LafargeHolcim can move on properly.

Chief executives from over 30 companies attended the Global Cement and Concrete Association (GCCA) inaugural event last week in London. Its first president Albert Manifold, the chief executive officer (CEO) of CRH, laid out the line by saying that, “For the first time we have a global advocacy body.” He followed this up by emphasising that ‘our product’ is the most used man-made product in the world. Just like the Cement Sustainability Initiative (CSI), the body the GCCA is partly-replacing, it is a CEO-led organisation. The target is very much about giving a global voice to the cement and concrete industries and the vertically integrated companies that produce these products.

Along with the head of CRH, the leaders of LafargeHolcim, HeidelbergCement, CNBM, Votorantim, Buzzi Unicem and Eurocement, amongst others, were all on the attendance list too. That kind of representation gave the event a charged air and a real sense of intent. At present the association says it represents 35% of global cement production and its aim is to reach 50%. That compares to the 30% base that the CSI had.

Representatives from some major cement associations were also present, including Europe’s Cembureau, the Federación Interamericana del Cemento (FICEM), the Canadian Cement Association and the VDZ. The only thing stopping the US Portland Cement Association being there was reportedly the Thanksgiving holiday. Although not comprehensive, that kind of representation suggests serious interest from the regional cement associations. The word from the GCCA CEO Benjamin Sporton was that the GCCA is here to provide a global level of coordination to the advocacy and sustainability side of the industry dealing with global organisations like the United Nations (UN), development banks, other associations and non-government organisations (NGOs).

How this will work in practice has yet to be seen, but at the very least, the GCCA can take over the work of the CSI and run with it. The word from the attendees we spoke to was uniformly positive for the association. It was seen as a long-overdue move to finally give the industry some sort of uniform voice at a global scale. In this sense it is catching up with similar bodies in industries like wood and steel. One benefit from moving from the CSI to a full advocacy organisation is that the industry can actually talk about the good things it does rather than being limited to sustainability and environmental data reporting. It seems like a small change in focus but it’s a big shift in mind-set.

A cynic might suggest that the exercise is one of a dirty industry trying to wrest the Overton window, or window of public discourse, back from legislators facing mounting environmental pressure. The latest UN Emissions Gap Report for 2018, for example, reported this week that CO₂ emissions rose in 2017 after four consecutive years of decline. This is the latest environmental report in a long line pointing out bad news. Yet, the GCCA’s unwritten mantra, that concrete improves lives, is sound. Somebody or something needs to link it all up. That somebody might just be the GCCA.

A review of the inaugural annual general meeting and symposium of the GCCA will be published in a forthcoming issue of Global Cement Magazine.

Italy: CIFA has celebrated its 90th anniversary with an update to the company museum, the launch of a special edition vehicle-mounted pump and a series of special events. The museum, based at the company headquarters in Senago, has introduced news areas dedicated to hybrid technology and carbon fibres. The special edition pump products are available for the K42L, K45H and the new K47H models and include special anniversary colours, celebratory plaques and a 90th anniversary logo. The company was specialises in concrete pumps was originally founded on 7 July 1928 by Carlo Ausenda.

Egypt: Cemex is supplying around 0.76Mt of cement to build tunnels underneath the Suez Canal. It is also providing over 0.5Mm³ of concrete for the projects that will link the mainland to the Sinai Peninsula and the development of a commercial seaport. The work is being managed by a joint venture with Orascom Construction and Saudi Arabia’s Osman Ahmed Osman. The two tunnels will extend from the outskirts of Port-Said to the Sinai Peninsula, passing under the Suez Canal. The construction of the two 4km tunnels required the installation of three ready-mix batch plants on site to fulfil the project’s concrete demands.

US: CarbonCure has demonstrated an integrated CO₂ capture and utilisation (CCU) process from cement for concrete production in January 2018 at Cementos Argos’ Roberta plant in Calera, Alabama. The consortium - comprising Carbon Cure, Sustainable Energy Solutions (SES), Praxair, Cementos Argos and Kline Consulting - says it is the world’s first project to collect cement kiln CO₂ for subsequent utilisation downstream in concrete production and construction.

CO₂ emissions from the Roberta cement plant were captured by SES’ Cryogenic CO₂ Capture technology, transported by Praxair and reused in Cementos Argos' Glenwood, Atlanta concrete operations equipped with CarbonCure's CO₂ utilisation technology. The concrete manufactured with the waste CO₂ from the Roberta cement plant was then used in a local construction project in the greater Atlanta area. Design partners and fellow members of CarbonCure’s Carbon XPRIZE team such as LS3P Architects, Uzun + Case Structural Engineering, and Walter P Moore Structural Engineers completed the end to end integrated solution by creating demand for CarbonCure concrete products in the marketplace. Kline Consulting oversaw the commissioning and reporting of the industrial demonstration.

The project was an extension of Team CarbonCure's participation in the US$20m NRG COSIA Carbon XPRIZE Challenge, which incentivises and accelerates the development of integrated CCU technologies and new markets that convert CO₂ emissions from coal and natural gas power generation into valuable products.

UK: Nine cement and concrete companies have launched the Global Cement & Concrete Association (GCCA), a new association that intends to develop the sector’s role in sustainable construction. The association also wants to build innovation throughout the construction value chain, in collaboration with both industry associations and architects and engineers.

The GCCA will be led by international cement companies and headquartered in London, complementing and supporting the work done by existing associations at national and regional level. Membership of the GCCA is available for cement manufacturers from all over the world that share the organisation’s values, and partnerships will be developed with organisations that share its vision. GCCA’s founding members are Cemex, CNBM, CRH, Dangote, Eurocement, HeidelbergCement, LafargeHolcim, Taiheiyo and Votorantim. They represent 1046Mt of cement production capacity, according to the Global Cement Top 100 Report.
