China: CNBM’s revenue rose by 0.5% year-on-year to US$38.9bn in 2020 from US$38.7bn in 2019. Its profit for the year grew by 17% to US$3.30bn from US$2.81bn. However, its cement sales revenue fell by 3% to US$19.5bn from US$20.0bn and its concrete sales fell slightly to US$7.80bn. Cement-based earnings before interest, taxation, depreciation and amortisation (EBITDA) fell slightly to US$5.73bn and concrete-based EBITDA rose by 53% to US$794m. Both cement and concrete sales volumes grew slightly to 340Mt and 112Mm³ respectively. Overall group revenue rose due to sales by the group’s new materials and engineering divisions. The share of its overseas revenue fell to 2% in 2020 from 13% in 2019 due to declines in most regions with the exception of the Americas and Oceania.

“2020 was an extraordinary year, faced with severe and complicated domestic and international environment, especially the serious impact from Covid-19,” said Cao Jianglin, chairman of CNBM. He added, “The foundation of economic recovery in China is not yet solid, and the task of industry transformation and upgrading is arduous.” The company plans to continue implementing supply side structural supply reforms and work towards government CO₂ emission peak targets and carbon neutrality plans.

Egypt: Developer Mountain View has awarded a 300,000m³ concrete supply contract to Lafarge Egypt, part of Switzerland-based LafargeHolcim. Mountain View will use the concrete to build its Mountain View iCity in East Cairo. The investment in the project totals US$12.7m.

The producer has also signed a memorandum of understanding with the Egyptian National Research Centre to undertake initiatives aimed at enhancing construction.

UK: Breedon Group’s revenue remained stable in 2020 at Euro1.08bn. Its underlying earnings before interest and tax (EBIT) fell by 34% year-on-year to Euro89.3m in 2020 from Euro136m in 2019. Cement sales volumes stayed stable at 2Mt but ready-mixed concrete sales volumes dropped by 13% to 2.6Mm³ from 3Mm³. The group reported a strong second half of 2020 following coronavirus-related disruption.

“Although we remain mindful of the ongoing impact of Covis-19, with the worst of the pandemic now hopefully behind us and some welcome clarity on Brexit, I believe the prospects for Breedon and for our industry are increasingly positive,” said Pat Ward, Breedon Group’s chief executive.

US: R-Tec Creations has launched New World Concrete, a single-stone Portland pozzolan concrete. R-Tec creations classifies the product as super ultra high performance concrete (SUHPC) for its compressive strength. It developed the concrete for use in construction in hurricane and earthquake-affected areas.

US: Lehigh Hanson has signed a collaboration agreement with materials technology company Fortera. Under the agreement, the companies will establish a carbon capture and storage (CCS) system at the producer’s 0.8Mt/yr integrated Redding Cement plant in Shasta district, California. The system will produce a cementitious material for use in concrete production. The material will be the first of its kind to be produced at a cement plant.

"This collaboration with Lehigh Hanson will prove the commercial scalability, the quality of the final product, and the competitive economics of the Fortera process," said Ryan Gilliam, chief executive officer and co-founder of Fortera. He added that the Fortera process (ReCarb) has been designed to utilise the existing cement infrastructure, from the quarry to the kiln, but with less CO₂ emissions, lower energy, and lower processing temperatures, leading to 60% lower CO₂ emissions per tonne of product.

Switzerland: Sika has developed ReCO2ver, a process which produces limestone, sand and gravel from the combination of concrete and CO₂ with an additive developed by the supplier. The process enables demolition companies to completely recycle used concrete, while storing captured CO₂ at a rate of 60kg/t of crushed concrete. The materials produced can be used as aggregates to make concrete of comparable strength to an all-new product.

Chief executive officer Paul Schuler said, "The five largest European Union countries alone generate roughly 300Mt/yr of old concrete. With complete recycling of these materials, up to 15Mt/yr of CO₂ emissions can be stored. We are convinced that our new process has the potential to benefit both our customers and the environment."

Germany: Former HeidelbergCement technical director Rainer Nobis has published a book entitled Illustrated History of Cement and Concrete. The over 300-page volume traces the development of cement and concrete from prehistory to the present day, exploring the question of how cement and concrete came to be so closely intertwined with our prosperity, way of life and mobility. It is both a technical history and a story of the people who contributed to the development and application of cement and concrete. Nobis described the book as of interest both to cement experts and laypeople. More than 700 pictures accompany the text. Its first edition is available in English and German versions.

The Illustrated History of Cement and Concrete is currently available prior to its launch on online retailers in mid-March 2021.

Spain: Cemex is supplying cement to the site of the upcoming Santolea Canyon dam in Aragon. The 59m-high structure will hold a 105hm³ reservoir, which will provide water to 2000 surrounding farms. Concrete pouring began at the site in March 2020 and is scheduled to reach completion in mid-2021.

Europe, the Middle East, Africa, and Asia regional president Sergio Menendez said, "We are very proud of our participation in the construction of the Santolea Canyon dam, a key project requiring materials and solutions of the highest technical and environmental specifications. The new Santolea dam will greatly contribute to support sustainable growth in the region”.

Saudi Arabia: Saudi Readymix has received its certification from the American Concrete Institute (ACI) to provide ACI certified courses. The courses form a minimum qualification for concrete industry workers.

Saudi Readymix’s Commercial and Technical Director, Chris Leptokaridis said, “We are extremely proud of our research and development facility, it’s important role as a company knowledge hub and testing ground of all our future materials. It is the most advanced and well-equipped research facility of any readymix producer in the Middle East.”

The concrete producer will start accepting candidates for its courses in March 2021. It will offer ACI trainings courses in concrete field testing and concrete strength testing.

Europe: Cemex commissioned seven new bolt-on investments across Europe in January 2021. The company says that all of the investments are aligned to its key priorities of climate action, sustainable construction and earnings before interest, taxes, depreciation, and amortisation (EBITDA) growth. They include advances in fossil fuel reduction, lower CO₂ footprint products, circular economy investments and products that demonstrate life cycle CO₂ and energy consumption advantages for buildings. It made various changes at its cement plants, for example the installation of a new alternative fuel (AF) system in the Czech Republic. In France and the UK, it made circular economy and recycling improvements, and shifted to lower-CO₂ cement production in Croatia and lightweight concrete production in Spain. Additionally, it made efficiency upgrades to sites in Spain and the UK.

Europe, Middle East and Africa regional president Sergio Menendez said, “We have made a strong start to our 2021 ambitions to both grow our business and improve our climate impact. In 2020, we achieved our ambition of a 35% reduction in our CO₂ emissions compared to our 1990 baseline in Europe. We are also the first company in our sector to align our Europe operations to the EU aspiration to reduce CO₂ emissions by at least 55% by 2030. These investments represent further advances towards this 2030 target, as well as to deliver net zero CO₂ concrete globally by 2050.”
