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.”

India: JSW Cement has launched its first commercial ready-mix concrete plant at Chembur in Mumbai, Maharashtra. The plant has a capacity of 120m3/hr across two production lines. It will serve construction in south and central Mumbai. The technology for the plant was supplied by Germany-based Schwing Stetter. The company plans to establish three further batching plants in Mumbai, covering Navi Mumbai, Thane and western Mumbai.

“JSW Concrete was successfully piloted at our captive plants at Dolvi and Vijaynagar and used in the expansion projects of JSW Steel. The experience gained from these projects gave us enough confidence to offer this unique concrete product to our large project customers,” said TN Viswanathan, Vice President of JSW Cement.

Poland: Switzerland-based LafargeHolcim subsidiary Lafarge Polska has launched Aggneo, a recycled aggregate recycled from demolition-sourced concrete. The producer says that Aggneo offers high consistency and a lower density than mined aggregates, resulting in material savings. Besides reducing waste, the product also lowers the carbon footprint of delivery by 66%, according to the company. The building materials producer aims to manufacture 1Mt/yr of recycled aggregated by 2030.

Czech Public: Ukraine-based Betonmash has fulfilled an order for a Granit-42 ready-mix concrete batching plant from a customer in the Czech Republic. The 42m3/hr-capacity plant consists of a 750l rotary mixer and 75t hopper. Italy-based Bonfiglioli supplies the Grant-42’s drives, Italy-based Camozzi supplies its pneumatic components and Italy-based WAM supplies its screw conveyors. It uses sensors produced by Netherlands-based Zemic.

Egypt: Saudi Arabian-based Mohammed Hassan Al Naqool Sons has started pilot production at its Cement Industries subsidiary based in El Alamein. The project has an investment of around US$5m. It will manufacture cement-based products, including blocks and concrete. Commercial production at the site is expected to start in the third quarter of 2021.

UK: SigmaRoc intends to offer a cement-free alternative for every product in its precast concrete portfolio from January 2022. The producer claims it is the only company to do this. The change will effect products made by its Product Group including Allen Concrete, CCP Building Products and Poundfield Precast. The move follows the launch of its Ordinary Portland Cement free Greenbloc product in February 2021.

Managing director Michael Roddy said, “Greenbloc sets the bar for bringing a cement-free alternative to a traditional building material into mainstream use, but it was only ever the start of our low-carbon journey.” He added “The benefits of using cement as a building material are undisputed from an application perspective, however the carbon required in the manufacturing process cannot be ignored. Our aim is simple. The market is changing and understands the need to acknowledge, address and action a tangible approach to decarbonisation. We want to give architects, contractors and specifiers the choice of using an ultra-low carbon cement-free alternative to precast cementitious products.”

Canada: Testing specialist Giatec has launched SmartMix, a web-based software product for concrete ingredient optimisation. It is intended to help concrete users lower their cement construction for jobs. The supplier estimates that the tool could lower the CO₂ emissions of concrete production by 400Mt/yr, the equivalent carbon footprint of 110m cars.

Head of research and development Andrew Fahim said, “Artificial intelligence (AI), machine-learning algorithms and advanced analytics on construction jobsites are going to pave the path forward for our industry to meet increasing infrastructure demands. I am proud to provide contractors and producers AI tools to make impactful decisions and get ahead of the competition by bringing more value to their customers while reducing the carbon impact of their products.”

India: LafargeHoclim subsidiary Ambuja Cement has launched Ambuja Cool Walls, a product consisting of its aerated pre-cast concrete blocks. The producer says that Cool Walls have improved strength compared to walls made of brick. They also increase buildings’ insulation, according to the producer.

US: Aggregate producer Vulcan Materials Company has agreed to buy US Concrete for US$1.29bn.The transaction has been unanimously approved by the boards of directors of both companies and is expected to close in the second half of 2021, subject to US Concrete shareholder approval, regulatory clearance and other customary closing conditions.

Tom Hill, Chairman and chief executive officer of Vulcan Materials Company, said, "US Concrete is an important Vulcan customer in a number of key areas, and this transaction is a logical and exciting step in our growth strategy as we further bolster our geographic footprint.”

US Concrete runs 27 aggregates operations serving California, Texas and the Northeast US. It shipped 12.6Mt of aggregates in 2020. Vulcan also said that the acquisition represented a ‘natural’ addition to Vulcan's business. The deal also adds US Concrete’s ready-mixed concrete operations to Vulcan's existing concrete business.

Canada: The Cement Association of Canada (CAC) and the government have published a joint statement detailing their plant to develop a roadmap to net-zero carbon concrete. When launched in December 2021, the roadmap will provide Canadian cement producers with the policies, tools and technologies to contribute to the achievement of net-zero concrete by 2050. The plans will cover areas including: supporting the low-emissions building materials supply chain, building an innovative opportunities framework and engaging stakeholders. According to the statement, the roadmap will offer total potential CO₂ reduction of 15Mt by 2030, and 4.0Mt/yr thereafter.

The partnership will establish a CAC-led Industry-Government Working Group in collaboration with the National Research Council the Standards Council of Canada and Innovation, Science and Economic Development. Among its tasks will be the publication of updated environmental product declarations.
