Betolar launches Geoprime concrete products in India
11 October 2022India: Finland-based Betolar has launched its first concrete products manufactured using Geoprime on the Indian market. Geoprime is an additive designed for use in cement-free concrete production with ash and ground granulated blast furnace slag (GGBFS). The new concrete product range consists of precast blocks, paving slabs and tiles, and is currently on display at World of Concrete India in Mumbai, Maharashtra.
Betolar's India managing director Abhishek Bhattacharya said "We are happy to introduce our first products to our customers for the Indian markets. We have now moved from laboratory tests into the production phase, and can show concretely how well this solution works. It is great to hear the feedback from the concrete industry in the region to our sustainable solution. Decarbonisation of the concrete industry is a very current and important topic."
Seratech's carbon-neutral cement wins Obel Award 2022
10 October 2022UK: Denmark-based architecture fund Henrik Frode Obel Foundation has named Seratech as winner of its Obel Award 2022. The award recognises architectural contributions to global development. Seratech has developed an olivine-based composite cement produced using CO2 from flue emissions, which can sequester double the CO2 of ordinary Portland cement (OPC). When used as 40% of a blend with OPC, it is able to completely offset the emissions of concrete production.
Team member Barnaby Shanks said "The beauty of the idea is that you can just use it as normal concrete. There are other carbon-neutral materials, but they can be limiting because they can only be precast, cured in a lab in special conditions and shipped elsewhere. We want people to retain the freedom to use concrete the way that they are used to. We don’t want to limit people in any way because we’ll just lessen the amount of impact we can have."
UK: Breedon Group, together with Australia-based First Graphene, Morgan Sindall Construction & Infrastructure and the University of Manchester, is developing a new reduced-CO2 graphene-enhanced cement. The consortium is currently formulating the cement using varying doses of First Graphene’s PureGRAPH graphene-enhanced grinding aid. The project received a research grant from the UK government earlier in 2022. First Graphene says that the study involves one of the largest commercial trials of its kind to date globally. It is simultaneously collaborating on another similar trial with a Europe-based speciality chemicals producer.
On 29 September 2022, First Graphene launched its latest range of graphene-enhanced cement grinding aids and concrete additives. These join recent launches PureGRAPH AM, an admixture developed in collaboration with South Africa-based Nanoproof/Glade Chemicals, and HexMortar, a dry mortar mix which will be distributed by New Zealand-based GtM Action.
First Graphene says that its cement and concrete segment’s order pipeline totals US$113m in value. Managing director and chief executive officer Michael Bell said “It is pleasing to see our efforts, and those of our collaboration partners, coming to fruition at a commercial scale. One of the primary drivers for the adoption of graphene solutions in this segment is the reduction of CO2 emissions. We’re seeing considerable benefits both in the immediate reductions that can be achieved through the use of graphene-enhanced grinding aids, as well as the potential reductions in concrete usage because of the enhanced physical properties these products provide.” Bell concluded “Working with industry-focused partners such as Nanoproof/Glade Chemicals, GtM Action, Breedon Cement and Fosroc opens the way to an estimated addressable market of more than 12,000t of PureGRAPH across the medium to long term.”

Romania: Holcim Romania has published four new environmental product declarations (EPD) for its products, including ECOPlanet cement and ECOPact concrete. It says it is the first construction materials manufacturer in the country to do so. The subsidiary of Switzerland-based Holcim first started makings its EPDs available in 2014 for cement, concrete and aggregate products. These were revalidated in 2019 and again in 2022.
Update on China, August 2022
31 August 2022The larger cement producers in China have published their half-year financial results and the numbers are looking grim. Starting with data from the National Bureau of Statistics of China, cement output in the country fell by 14.5% year-on-year to 979Mt in the first half of 2022 from 1.14Bnt in the same period in 2021. This is the lowest first half output figure since 2012. The decline on a monthly basis started in May 2021 and has carried on consistently since then. Rolling cumulative annual output hit a low of 2.18Bnt in July 2022, the lowest figure since at least the start of 2019 and well before the coronavirus pandemic started.

The financial figures from the cement producers have mostly followed this trend. Of the companies covered here, Anhui Conch’s drop in sales revenue was the most distinct at 30% year-on-year to US$8.14bn. However, Jidong Cement actually managed to increase its revenue and Huaxin Cement’s decrease was fairly small, possibly due to its growing stable of overseas projects. None of these companies could avoid falling cement and clinkers sales volumes though. Again, Anhui Conch is the outlier here with a larger fall in sales volumes proportionally at nearly 40% compared to around 20% for the rest. Chen Bolin, the deputy secretary-general of China Cement Association (CCA), told the 21st Century Business Herald newspaper that of the 20 or so listed cement companies that have published their half-year reports by the end of August 2022, more than half had reported falling sales revenue and net profit and only one company had managed to increase its net profit.

The financial reports from the Chinese cement companies detailed here have been fairly light on the reasons for the current state of the sector. Repeated coronavirus outbreaks, instability in the real estate market, a lack of funding for infrastructure projects, growing energy and raw materials costs, pressure on prices and a generally weak economy have all been blamed for the situation. Media channels outside of China have continued to scan the country’s real estate sector for signs of collapse following Evergrande’s problems in 2021. However Chen Bolin diplomatically held back by describing the real estate market as not yet stabilised and a drag on cement demand. Instead he hoped that large-scale infrastructure projects would offer some form of relief.
One last point to note, that both the CCA has made and could be seen in some of the company reports, is that some of the Chinese cement companies are already starting to diversify their businesses. This is in parallel to what some of the larger western-based multinational cement producers have also been doing in recent years with forays into concrete, light building materials and construction chemicals. CNBM already has large concrete, light building materials and engineering subsidiaries. However, Huaxin Cement and Anhui Conch have also started to branch out recently into aggregates, concrete and new energy generation, in the case of the latter company. Things may get worse before they get better, especially depending when or if the Chinese government decides to act on the real estate market. However, whatever kind of adjustment the cement sector may face, there are some signs present already of what some of the companies may do next.
China: China Resources Cement’s (CRC) turnover fell by 21% year-on-year to US$2.05bn in the first half of 2022 from US$2.57bn in the same period in 2021. Its profit decreased by 50% to US$230m from US$463m. Its cement and concrete sales volumes dropped by 26% to 30.7Mt and 23% to 5.4Mm3 respectively. However, its clinker sales volumes rose by 5% to 2Mt. The group also reported that the capacity utilisation rate for its cement and clinker production lines were 70% and 87% in the first half of 2022 compared to 97% and 108% in the same period in 2021.
Lafarge Canada installs electric vehicle charging stations at batching plant in Vancouver
11 August 2022Canada: Lafarge Canada has installed its first electric vehicle charging stations at its Kent Avenue ready-mix concrete batching plant in Vancouver, British Columbia. The company’s Vancouver team built the four stations with US$39,200 in funding from Lafarge Canada and US$15,700 in funding from BC Hydro’s CleanBC Go Electric Vehicle charger rebate programme. Dow Jones Institutional News has reported that the company plans to establish 96 further stations at 30 sites in British Columbia, Alberta, Manitoba and Saskatchewan. It says that the electric vehicle charging network will enable it to eliminate 188t of CO2 emissions by 2028.
Lafarge Western Canada chief executive officer Brad Kohl said "We are thrilled that Western Canada has opened the first electric vehicle charging stations to kick-start this exciting effort planned across our Canada operations to advance our goal of net-zero as part of our environmental commitments."
