Czech Republic: Cemex Czech Republic has successfully commissioned its Prague-Libuš ready-mix concrete batching plant in Prague, following an upgrade. The upgraded plant can now process five types of cements and admixtures, including Cemex’s Vertua reduced-CO₂ concretes and recycled aggregates. Cemex Czech Republic has installed two recycled aggregates production plants at the site to process residual concrete.

Cemex’s vice president materials, Central Europe, Ruediger Kuhn said “Our plant in Libuš forms an important part of our operation in the Czech republic, thanks to its interesting location in the wider centre of the capital and in the immediate vicinity of the planned construction of the Prague Metro D line. We are therefore very pleased to have this site reopened following a considerable investment.” He added “The development at this site confirms Cemex’s determination to offer its customers superior quality products while also meeting its sustainability objectives, supporting the circular economy and reducing emissions wherever possible.”

Kuwait: Kuwait Portland Cement has won a contract with China Gezhouba Group to supply ready-mix concrete for a housing development in Saad Al-Abdullah City. Reuters has reported that the project will take four years and cost US$117m.

Germany: An activist or activists have claimed responsibility for starting a fire that engulfed five trucks, multiple cement silos and part of a building at a Cemex Deutschland ready-mix concrete batching plant in Kreuzberg, Berlin, Zeit Online News has reported.

In a statement posted on news website Indymedia DE, the purported culprit(s) claimed that they targeted the plant for its involvement in supplying concrete for the A100 road expansion project in Berlin. Additionally, the statement alleged that Cemex has supplied concrete for illegal Israeli military checkpoints in Palestine, for which reason the self-proclaimed arsonists chose to target the group’s German subsidiary.

Switzerland: Holcim has partnered with the Federal Institute of Technology (ETH) Zurich’s Block Research Group, incremental3D and Zaha Hadid Architects Computation and Design Group for the launch of Phoenix, a 3D-printed concrete bridge made using reduced-CO₂ circular technologies. The bridge employs Holcim’s ECOCycle recycled 3D-printing concrete and stands through compression, without reinforcement, reducing the volumes of materials used by 50% compared with conventional construction methods.

Holcim head of global research and development Edelio Bermejo said “I am thrilled to unveil Phoenix, a monument to sustainability and the result of a fruitful collaboration with our partners to meet a common goal: demonstrating that essential infrastructure can be designed and built in a way that is circular and low-carbon today. This project showcases the impact that innovation can have in Holcim’s mission to decarbonise building for a net-zero future.”

US: C-Crete Technologies poured its zeolite-based concrete for the construction of a 20t slab-on-grade foundation and set of steps in Seattle. The concrete uses zeolite as a binder, removing the need for cement.

C-Crete Technologies founder and president Rouzbeh Savary said "Our successful 20t concrete pour in Seattle using the zeolite-based binder is an important step in our quest to revolutionise construction. This landmark use of the product epitomises C-Crete's commitment to reshaping the industry through environmentally conscious innovations. By tapping into various natural rocks like zeolite and converting them into cementitious binders we're forging a path toward truly sustainable infrastructure."

Mexico: Property developer Immobiliaria Ancore will use Cemex Mexico’s Vertua reduced-CO₂ concrete in the construction of the upcoming 100-storey Rise Tower in Monterrey. Cemex will supply a high-altitude concrete pouring system for the project. The concrete supplier said that the development aims to secure LEED, WELL, Green Globes, bEQ and NMX-164 certifications.

Cemex Mexico president Ricardo Naya said “We’re honoured to be working on a project that will establish the new standard for sustainable high-rise construction in Latin America. Cemex brings vast experience in sustainable construction, providing lower-carbon building materials, lower-waste practices and zero use of potable water in our concrete production.”

US: Cemex USA supplied water-permeable concrete from its Vertua range for the renovation of the Bryant-Denny American football stadium at the University of Alabama. The producer says that this will reduce the project’s CO₂ emissions by 40%, while also facilitating rainwater harvesting and preventing the stadium’s field from flooding.

Cemex USA president Jaime Muguiro said “These types of projects exemplify Cemex’s versatility. From housing to large-scale infrastructure, we are able to deliver tailor-made solutions that best suit our customers’ needs. Thanks to our extensive portfolio of high-quality building materials and solutions, we can participate in such iconic projects and support more sustainable construction.”

Bahamas: Partanna Global has unveiled its first carbon negative, climate-resilient Home for the World in Nassau. The residence will remove 182.6t/yr of CO₂ from the atmosphere. It is the first of 30 planned units, as part of a project to eventually build 1000 Homes for the World in partnership with the Bahamian government.

US: Cemex USA has poured 18,300m³ of Vertua reduced-CO₂ concrete in the construction of the Centennial Tower at Houston Methodist Hospital in Texas. Cemex USA says that it successfully completed the 20hr pour at the world’s largest medical complex without interrupting surrounding emergency services.

President Jaime Muguiro said “Cemex’s purpose of building a better future comes to life when we participate in projects that improve people’s quality of life, particularly in the area of health services, in the communities in which we serve. Not only are we providing expert logistics and resilient materials, but we are also providing an alternative to lower the carbon footprint of the project with our more sustainable solutions.”

Mexico: Holcim Mexico says that its supply of cement to the government’s Tren Maya railway project is 170,000t/month. This corresponds to 50 – 60% of its total production volumes. Local press has reported that construction of the 1500km-long Tren Maya railway will consume 1Mm³ of concrete. Holcim supplied its cement for Sections 1 – 3 of the line between 2020 and 2022. It is currently supplying Section 5, which is 50% complete. The cement comes from the company’s Orizaba, Veracruz, plant; its Macuspana, Tabasco, plant and its Mérida, Yucatán, plant.

Holcim Mexico’s infrastructure development manager Fernando Roldan said "Our participation has been a challenge, but the relationship we have with the suppliers and with the construction companies in charge of the railway has allowed us to meet the requirements."
