US: Dome Technology has commissioned a 169,000t dome at Lehigh Cement's Mitchell cement plant in Indiana. The dome is equipped with three reclaim tunnels, enabling 83% live reclaim.

Dome Technology sales manager Lane Robertssaid “It’s a colossal project. It’s one of our bigger domes as far as storage capacity goes."

UK: Cemex UK has commissioned a new 25kg plasticcement bag packing line at its Rugby cement plant in Warwickshire. The line will operate alongside an existing paper bagging line.

Cemex UK's packed cement sales manager Graeme Barton said “The packaging of our products is under routine scrutiny to meet customer demand and reduce waste. We have listened to what our merchants and customers need, and by investing in higher, more reliable capacity, Cemex can now meet the demand from the market in peak months with greater confidence. In turn, our stockists can meet their customers’ requirements by supplying what they need, in a format that works better for them. Our merchants and end-users are already seeing the immediate benefits of the new packaging by reporting fewer breakages in branch and onsite – which helps to cut down on waste."

Trinidad & Tobago: Workers at Trinidad Cement’s Claxton Bay cement plant have launched a protest at the plant against an alleged breach of employment contracts. Troubled Company Reporter Latin America News has reported that Trinidad Cement has allegedly underpaid employees for more than seven years, with no cost of living allowance or gain share payments, and resulting pension miscalculations, according to a union representing the workers.

A trio of slag cement stories have been in the sector news this week with reports from Australia, France and Sri Lanka. Of note from the first two reports is a focus on supplies of slag.

The first concerns Hallett Group’s US$80m supplementary cementitious materials (SCM) project in South Australia. This will see the company process slag and fly ash sourced from sites in the region to manufacture blended cement products and standalone SCMs. These will be principally milled, blended and distributed from a site at Port Augusta. However, an additional distribution site at Port Adelaide is also planned that can both import and export the company’s products in a bid to cut down on supply chain risk, particular for its mining customers. The company says it will replace up to 1.15Mt/yr of cement when fully operational, although initial production looks set to be about a third of this based on local media reports. Commissioning of the Port Adelaide distribution hub is scheduled for May 2023, following by the Whyalla Granulator in January 2024 and the Port Augusta processing plant in June 2024. Pointedly, Hallett Group is explicit about where is plans to source its SCMs from: Nyrstar Port Pirie and, potentially, Liberty GFG.

The second slag-themed story hails from France, where Hoffmann Green Cement has acquired ABC Broyage, which operates a slag grinding plant in North Dordogne. Like the project in Australia above, Hoffmann Green is focused on its supply chain. With this acquisition it will be able to grind its own blast furnace slag instead of buying it. Raw blast furnace slag will be imported via the port of La Rochelle where the company has storage silos. It will then be ground at the former ABC Broyage site and sent on to Hoffmann Green’s H1 and H2 production sites, located at Bournezeau in the Vendée region. Finally it will use it to manufacture its H-UKR and H-IONA cement products. There is no mention of how much the acquisition is costing Hoffman Green. Instead the emphasis, according to company founders Julien Blanchard and David Hoffmann, is very much to, “strengthen our control over our supply and secure our margins in the current highly inflationary context.”

Finally, the week’s third slag-themed cement story is from Sri Lanka, where local media reports that Insee Cement has started producing Portland Composite Cement, using SCMs such as slag, at its Ruhunu grinding plant. This story follows the trend of cement producers around the world switching to greater usage of blended cements, often for sustainability reasons. Unfortunately, political events in Sri Lanka are overshadowing everything else locally, with the president having fled amid social unrest provoked by the ongoing and severe economic crisis. To this end Insee Cement has astutely also donated medical supplies this week to the intensive care unit at the Colombo National Hospital.

These slag stories are important for the cement sector can be demonstrated by a recent update to the Center for International Climate and Environmental Research - Oslo’s (CICERO) research on global CO₂ emissions from cement production. When it published its estimate for 2021 it found that overall emissions were 2.6Bnt in 2021 or just over 7% of the world’s total CO₂ output. What is worse though, is that its data suggests that cement-based emissions have steadily grown year-on-year from 1.2Bnt in 2002. Apart from a dip in 2015 they have kept on rising! This can mostly be attributed to the growth of the Chinese cement industry in the early 2000s suggesting that a tipping point may be reached in the current decade as lowering cement production CO₂ intensity finally kicks in.

Slag and other SCM-based blended cements fit in here as they are one of the ‘easiest’ ways to reduce the clinker factor of cement and concrete and thereby reduce the sector’s CO₂ levels. Hence they keep popping up on the various roadmaps and reports for the cement industry to reach net zero. The flipside of this however is that slag is becoming harder to source as the demand for granulated blast furnace slag increases and less new steel plants get built, especially in North America and Europe. Hence the focus on the supply of slag in the first two news stories above. Blended cements may be the future but getting there will be far from simple.

Vietnam: High costs have resulted in the cancellation of four planned new integrated cement lines by a local cement producer. Viet Nam News has reported that the producer in question presently faces costs of US$59.9 - 64.1/t cement, with a net loss of US$8.55 - 10.30/t. Coal prices are US$237/t, more than triple those at the start of 2022 of US$85.5/t. Gypsum and diesel prices rose by 50% over the first half of 2022. The producer reportedly attributed the coal price rise to the effects of the Covid-19 conflict and the Russian invasion of Ukraine.

Sri Lanka: Insee Cement's Ruhunu cement plant in Galle has begun producing Portland composite cement (PCC) using slag and fly ash. Insee Cement first produced PPC at its Puttalam cement plant.

Insee Cement's head of products and solutions Moussa Baalbaki said "Insee Cement introduced PCC for the first time to the local market in 2021 as part of a two-pronged approach: to create value for our customers by augmenting the sustainability performance in their constructions, and also to steer Sri Lanka's construction industry towards ambitious, globally benchmarked sustainable goals." Baalbaki continued "We are truly encouraged by the growing demand across the local market for PCC, and trust our production expansion to Galle is testimony to our commitment towards sustainable production practices."

Turkmenistan: Aumund has won a contract to equip Baherden Cement’s Ahal cement plant with three 300t/hr belt bucket elevators, three 450t/hr bucket elevators with central chain, a 1030t/hr double chain bucket elevator, two 200t/hr pan conveyors and 11 silo discharge gates. The equipment will serve raw materials preparation through to clinker grinding operations at the plant’s upcoming 1Mt/yr new line. Turkey-based cement plant builder Bilim Makina will receive the order.

Burundi: The government of Burundi says that it is ready to sign a credit letter with Dangote Cement for the establishment of a cement plant in the country. In this way, the government hopes to provide a long-term solution to the on-going national cement shortage. In the meantime, the government urged Dangote Cement to devise ‘modalities for the supply of construction materials’ into the country.

Burundian delegates at a meeting with Dangote Cement on 8 July 2022 said that Northwest Burundi is endowed with abundant limestone reserves.

CalPortland completed its acquisition of the Redding cement plant from Martin Marietta this week. As previously announced the transaction involved the integrated cement plant in northern California, related cement terminals and 14 ready mixed concrete (RMC) plants also in the state. However, CalPortland’s parent company Japan-based Taiheiyo Cement revealed this time round that it is considering buying the Tehachapi cement plant from Martin Marietta too. It says it has some sort of preferential purchase agreement in place, although a final decision is yet to be made.

If CalPortland and Taiheiyo Cement do end up buying the Tehachapi plant as well as Redding then it will mark a fairly quick turnaround of owners. HeidelbergCement subsidiary Lehigh Hanson announced that it was selling up assets in its US West region to Martin Marietta for US$2.3bn in May 2021. The deal was completed by October 2021. Then, CalPortland said it was buying the Redding plant in March 2022. From an outside perspective it was not clear what Martin Marietta might have had planned for its new assets. Over three quarters of Martin Marietta’s revenue in 2021 came from its Aggregates and RMC products. However, it is also a prominent regional US cement producer with two plants in Texas and two plants in California, along with associated terminals. So, building up its cement business in California didn’t seem unfeasible. Now, as can be seen, it is likely to be sticking to its primary focus of aggregates and RMC. It is also worth noting that California has some of the stricter CO₂ reduction policies in the US with a 40% reduction target for 2030 (compared to 1990 levels) and a local emissions trading scheme that started in 2013.

Looking at the local cement production base in California, the latest development with the former Lehigh Hanson plants shows the changing situation since the subsidiary of HeidelbergCement left the region. Beforehand, Cemex, Lehigh Hanson and CalPortland each had a similar clinker production capacity. Then, Martin Marietta took the lead and now CalPortland looks set to become the frontrunner if it buys Tehachapi. With the Redding deal completed it now operates three integrated cement plants in California and one in Arizona. Alongside this it runs 15 terminals in Alaska, Arizona, California, Nevada, Oregon and Washington – and – two terminals in Alberta and British Colombia in Canada. The Redding plant is also a distinctive addition to its portfolio as it is further north than the other clinker units.

United States Geological Survey (USGS) data shows that cement shipments to California grew by 5% from 10.05Mt in 2019 to 10.57Mt in 2021. So far in 2022, shipments to the state rose by 3.4% year-on-year to 3.56Mt for January to April 2022 compared to 3.44Mt in the same period in 2021. However, clinker production fell by 5% to 8.94Mt in 2021 from 9.45Mt in 2019. This trend seems to have continued into 2022 with a 9% fall to 2.54Mt for January to April 2022 compared to 2.81Mt in the same period in 2021. Despite this, California remained the second largest OPC and blended cement producer in the US in April 2022. In its Western US Regional Outlook in May 2022, the Portland Cement Association (PCA) forecast that the Pacific region of the US (including California) will experience flat growth in cement consumption in 2023 due to a slowdown in residential consumption. However, consumption is then expected to bounce back sharply in 2024 as the effects of the infrastructure bill take effect.

This suggests that CalPortland has picked an uncertain time to start buying cement plants in California. Yet only last year, in 2021, Cemex began restarting production at a previously mothballed cement plant in Mexico to supply the south-west US. Alongside all of this, environmental regulations are tightening. However, the key difference between Martin Marietta and CalPortland is that the latter is owned by Japan-based Taiheiyo Cement, which is more cement-focused than the aggregate and concrete oriented Martin Marietta. No doubt Taiheiyo Cement’s intention to become more international also played a part in its decision making. If CalPortland does decide to buy Tehachapi then this may give observers an idea of how much further its ambitions go.

Switzerland: Hoffmann Green Cement Technologies has launched a new joint venture with a Switzerland-based construction industry partner. Hoffmann Green Cement Technologies will hold a minority stake in the new subsidiary, which will produce its reduced-CO₂ clinkerless cement at an upcoming plant. The producer says that the unit will apply the vertical production model of its existing H2 plant in France.

Co-founders of Hoffmann Green Cement Technologies Julien Blanchard and David Hoffmann said "After signing our first contract outside France more than a year ago, we are proud to accelerate our international development through a licensing model for Hoffmann Green technologies and processes. The opening of this first subsidiary in Switzerland proves the attractiveness of our carbon-free solution without clinker outside our borders, and constitutes a structuring step in the development of Hoffmann Green."
