Germany: Former HeidelbergCement executive director Rainer Nobis’ Illustrated History of Cement and Concrete is now available in hardback online. The book traces the development of artificially produced building materials over 12,000 years, describing both the technical sequence of events and the political and economic environments in which they took place.

An unnamed reviewer said "The book is outstanding and comes at the right time. It has never been more necessary to recall the positive contribution of cement and concrete to mankind or to make it explainable. [Nobis] has more than succeeded!"

US: ForneyVault has partnered with Command Alkon to improve the quality control process for a mutual customer, Titan Virginia Ready-Mix. The concrete producer, a subsidiary of Greece-based Titan Group, previously relied on both suppliers’ products separately. Now, ForneyVault has integrated Command Alkon ‘s quality control technology into its own data collection software. It says that the integration will benefit the concrete producer’s testing capabilities. Titan Virginia uses Command Alkon’s CommandQC software product to validate the quality for its own internal ready-mix concrete products.

Command Alkon software product owner James Shilstone said “Forney’s decision to place their data in the cloud makes it easy to interface with CommandQC. Sharing data between the two programmes eliminates the need for double entry and makes the test results available to the QC manager more quickly.” ForneyVault vice president, platform development Scott Grumski added “Integration with Command Alkon’s software allows Titan’s quality control technician to lose the clipboard and pencil... The integration partnership reduces risk and advances compliance for Titan’s quality assurance programme.”

Germany: Switzerland-based Holcim has agreed to acquire ready-mix concrete and aggregates producer Heinrich Teufel. The Strassburg, Baden-Württemberg-based company employs 160 people across its operations in southern Germany. No value for the purchase has been disclosed and the transaction will be subject to regulatory approval.

Europe, Middle East and Africa regional head Miljan Gutovic said "The acquisition of Heinrich Teufel will strengthen our footprint in southern Germany in aggregates and ready-mixed concrete. We were especially impressed by their shared commitment to advancing the circular economy. We look forward to warmly welcoming the Heinrich Teufel colleagues joining our team.”

Canada: Lafarge Canada has signed a non-binding memorandum of understanding with carbon utilisation company, Carbon Upcycling Technologies. The agreement allows for the potential integration of Carbon Upcycling’s CO₂-embedded concrete additive into Lafarge operations and will explore opportunities to expand Carbon Upcycling’s operating capacity by developing larger processing facilities.

Carbon Upcycling produces an additive that makes concrete both stronger and more sustainable with the ability to reduce the carbon footprint of concrete by up to 25% on a lifecycle basis. Carbon Upcycling’s involvement into construction materials began in 2018 through its participation in the LafargeHolcim Accelerator program, which aimed to accelerate the growth of innovations in the building materials industry.

The deal aligns with Lafarge's Net-Zero 2030 pledge to accelerate green construction and combat the climate change crisis with low carbon concrete and circular economy solutions, and Carbon Upcycling goal to reduce overall CO₂ emissions by 600Mt by 2030.

France: Cemex France has inaugurated a multi-service green building materials outlet and recycling centre at Genevilliers in Paris, Île-de-France. The company says that the facility will stock its reduced-CO₂ Vertua concrete range. It will also receive construction waste, excavated earth and rubble for use in concrete production or resale as aggregates. The company will offer complete traceability of waste received, and non-recyclable waste will be used in quarry restoration.

France North director of materials Alain Plantier said, "Developing construction in high-growth urban locations requires circular economy solutions which mitigate climate change and save natural resources while improving the wellbeing of inhabitants." He added “Cemex is uniquely positioned to provide integrated solutions for building and maintaining more sustainable and resilient cities, and this new site demonstrates this perfectly. Clients in Paris need low-carbon construction solutions which perform throughout their life cycle. Working together with our clients, this site will help to reduce the carbon footprint of new projects in line with Cemex’s Future In Action strategy – committed to net zero CO₂.”

India: Researchers at the Visvesvaraya National Institute of Technology in Nagpur, Maharashtra, have shown in laboratory studies that an enzyme called urease found in watermelon seeds can strengthen cementitious materials and repair cracks in concrete. The Times of India newspaper has reported that the study found around a 22% increase in compressive strength, a 19% reduction in water absorption and improvements in durability. It is hoped that the food industry waste product could potentially be used to replace chemical admixtures commonly used in concrete production. Field studies are now set to follow.

Study leader associate professor Madhuwanti Latkar said, “Watermelon seeds are magic beans when it comes to importing strength to cementitious materials.”

New Zealand: Stevenson Concrete is set to bring concrete made using CarbonCure technology to the country in July 2021. The Auckland-based concrete producer is currently conducting final internal quality assurance at its Drury quarry and concrete plant before opening the product up on general sale. Canada-based CarbonCure’s technology uses a CO₂ mineralisation process during production to reduce carbon footprint of concrete.

"Along with a number of other carbon-decreasing initiatives we are using, this technology is going to change the way New Zealand builds houses, footpaths, roads, pipes, and thousands of other man-made, everyday objects. Stevenson has brought it into the New Zealand mainstream, just as this technology is used in countries like Singapore, North America and parts of Europe," said Anthony Bitossi, general manager of Stevenson Concrete.

Mexico: Cemex has launched a new brace of CO₂ emissions reduction targets. The group is now targeting CO₂ emissions below 475kg/t of cement and 165kg/m3 of concrete by 2030. These represent decreases of 40% and 35% respectively compared to 1990 levels. The group plans to invest US$60m/yr in efforts to meet its 2030 targets. It had previously targeted CO₂ emissions below 520kg/t of cement by 2030. It now aims to achieve the previous target by 2025. The group says it intends to reach the new targets through the use of alternative fuels with high biomass content, hydrogen injection, low temperature and low CO₂ clinker, decarbonated raw materials, optimisation of the kilns’ heat consumption and the reduction of clinker factor through the higher utilisation of blended cements in the market.

Chief executive officer Fernando Gonzalez said, “Climate action is the biggest challenge of our times, and Cemex is taking decisive action to address it. We commit to continue leading the industry in climate action.”

Kuwait: The Ministry of Commerce and Industry has banned all export and re-export of cement and other construction materials from Kuwait. However, it has allowed individual citizens to import construction materials for personal use. The ban is part of a raft of a measures intended to stem the increase in building material prices. The Kuwait News Agency has reported that cement prices rose after the resurgence of the coronavirus outbreak in India suspended Indian imports.

The ministry subsidises building materials including cement and concrete. In May 2021 it paid US$45m towards such subsidies. It continues to monitor the cement market and cement production for ‘unlawful’ price rises.

Kuwait’s cement production capacity is 9.0Mt/yr, while 2020 consumption was 6.0Mt.

Malawi: Switzerland-based Holcim says that the world’s first 3D printed school has opened in Salima district’s Kalonga village after a build time of just 18 hours. The EcoPact green concrete producer says the building provides a much-needed thirteenth school in Yambe, which still needs three more. Holcim’s green construction subsidiary 14Trees estimates that its 3D printing technology can meet Malawi’s school building needs by 2031, compared to after 2090 by conventional methods. The group said that the school proves that “3D printing can play a key role in bridging our world’s education infrastructure gap” with high-quality, sustainable, affordable and fast-paced construction, at scale.

Europe, Middle East and Africa regional head Miljan Gutovic said, “I am very proud of how our colleagues at 14Trees have deployed cutting-edge 3D printing technology to solve such an essential infrastructure need. Now that we’ve proven the concept in Malawi, we look forward to scaling up this technology across the broader region, with projects already in the pipeline in Kenya and Zimbabwe.”
