New UK concrete standard facilitates reduced-CO2 mixes
04 December 2023UK: The British Standards Institution has introduced a revised BS 8500 standard for concrete. The revised BS 8500 standard opens new possibilities for concrete producers to combine CEMII/A-L Portland limestone cement (PLC) and ground granulated blast furnace slag (GGBFS) in a wider range of exposure classes.
Mineral Products Association (MPA) chair and Cemex UK Materials managing director Lex Russell said “As the first UK company to introduce net-zero CO2 concrete in 2020, we have the ongoing responsibility to deliver lower carbon products at scale. The incoming changes to BS 8500 are welcomed by all at Cemex as it underpins our ambitious global goal for Vertua lower-carbon cement and concrete products to reach half of all cement and concrete sales by 2025.” He added “The amended concrete standard will serve to keep us on track with our decarbonisation goals, with the primary objective to become a net-zero CO2 company by 2050. It also aligns with our Future in Action programme to achieve sustainable excellence through climate action, circularity and natural resource management.”

US Department of Energy grants C-Crete Technologies US$2m
17 October 2023US: The US Department of Energy has awarded C-Crete Technologies US$2m in funding. C-Crete Technologies is developing a method for using CO2 captured at industrial sources or from the air as an ingredient in its cement-free concrete. The binder will produce almost no CO2 and continue to absorb more CO2 from the air over time. It offers scalability and cost-parity with conventional cement for concrete producers, according to the developer.
C-Crete Technologies president Rouzbeh Savary said “We are committed to crafting a cement-free, carbon-negative ready-mix concrete that doesn’t just mitigate CO2 emissions but actively contributes to reversing climate change. Our aim is nothing short of revolutionising this hard-to-abate, carbon-heavy sector.”
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.
Cemex Zement buys two iONTRON electric mixer trucks
14 September 2023Germany: Cemex Zement has bought two iONTRON eMixer electric ready-mix concrete mixer trucks from Putzmeister Group. The ready-mix concrete producer will deploy the vehicles in its Berlin operations, with one based at its Hohenschönhausen batching plant and the other at its Spandau batching plant. The vehicles offer a full eight-hour workday from a single overnight charge. When recharged using renewable energy, they can reduce journey’s CO2 emissions by 100%. They will also contribute to a reduction in urban air pollution and noise along the routes on which they operate.
Cemex Zement’s director materials Marcel Busch said "We are reducing emissions throughout our value chain, and transport plays an important role in this.” He added “We are investing in the electrification of our vehicle fleet at our sites throughout Germany."
