US: Cement mixer truck driver Allard Tigchelar, from Cemex USA’s Prescott, Arizona, ready-mix concrete plant, won gold representing his company at the National Mixer Driver Championship 2024 at the National Ready Mixed Concrete Association’s ConcreteWorks concrete conference in Aurora, Colorado, on 12 – 13 October 2024. Concrete Products News has reported that the championship pitted drivers against one another in an eight-challenge truck driving course designed to test vehicle handling skills. This was followed by vehicle inspection and an exam for drivers. Florida-based Maschmeyer Concrete driver Damion Wynter came second and Illinois-based Ozinga Ready Mix Concrete driver Garret Lytle came third.

Allard Tigchelar claimed US$6000 in prize money from the Truck Mixer Manufacturers Bureau. Wynter won US$3000 and Lytle US$1500.

UK: Saint-Gobain Construction Chemicals has won Tarmac's 2023 Innovation Challenge with its CHRYSO Quad Lab, a digital admixture optimisation tool. CHRYSO Quad Lab analyses sand prior to mixing, aiding in the reduction of the cement content of concrete.

Tarmac’s procurement manager, capex and sustainability, Mark Lewis said "Circularity within the materials industry is crucial to reaching net zero and reducing our impact on the environment. To achieve our sustainability ambitions, we know that collaborating with our suppliers is key to developing innovative new ideas and solutions.”

US: St Marys Cement won three national awards at the Slag Cement in Sustainable Concrete Awards 2023. The producer won the awards for supplying its slag cement for the construction of Wixom Assembly Park in Wixom, Michigan; of 333 North Water in Milwaukee, Wisconsin, and of Excellerate Manufacturing in Appleton, Wisconsin.

World: The Global Cement and Concrete Association (GCCA) has named the 15 anticipated deliverers of low-CO₂ cement and concrete production shortlisted for participation in its second Innovandi Open Challenge. The association chose the start-ups based on their potential to deliver CO₂ emissions reduction in the global cement and concrete sector in line with its Concrete Future 2050 Net Zero Roadmap. The applicants are presenting their pitches to GCCA members on 30 June 2023. All those accepted will gain access to members' plants, labs, networks and expertise. The following start-ups made the Innovandi Open Challenge 2023 shortlist:

GCCA cement director and innovation lead Claude Loréa said “We received more than 70 quality applications, so drawing up a shortlist was challenging." Loréa continued "Our essential industry needs something easily scalable and affordable. Those start-ups on the list demonstrated the most potential, and we look forward to hearing more about their ideas. But we’ll also be keeping in touch with other start-ups who didn’t make this year’s shortlist, with future projects in mind.”

UK: SigmaRoc subsidiary CCP has launched Greenbloc Standard, Ultra and Premium. The new designations correspond to 50%, 80% and 100% cement substitution. Professional Builder News has reported that Using Greenbloc Standard reduces structures’ CO₂ emissions by 77% compared with structures built with conventional ordinary Portland cement (OPC)-based blocks. For an average semi-detached house, this is equivalent to 2.7t of CO₂.

CCP general manager Phil Rotheram said “The expansion of our Greenbloc range continues our commitment to sustainable alternatives to our product offering as we fully commit to the challenges of removing embodied carbon from the built environment.”

Greenbloc Ultra featured in a gold medal-winning garden at the RHS Chelsea Flower Show 2023 in May 2023.

UK: Denmark-based architecture fund Henrik Frode Obel Foundation has named Seratech as winner of its Obel Award 2022. The award recognises architectural contributions to global development. Seratech has developed an olivine-based composite cement produced using CO₂ from flue emissions, which can sequester double the CO₂ of ordinary Portland cement (OPC). When used as 40% of a blend with OPC, it is able to completely offset the emissions of concrete production.

Team member Barnaby Shanks said "The beauty of the idea is that you can just use it as normal concrete. There are other carbon-neutral materials, but they can be limiting because they can only be precast, cured in a lab in special conditions and shipped elsewhere. We want people to retain the freedom to use concrete the way that they are used to. We don’t want to limit people in any way because we’ll just lessen the amount of impact we can have."

Germany: The Ministry for Economy and Climate Protection has presented HeidelbergCement with its German Climate and Environment Innovation Prize (IKU) for its ReConcrete-360° concrete recycling process. The process retrieves hardened cement paste from waste demolition concrete for use in place of limestone in clinker and cement production. The recycled material can also bind CO₂ to act as a carbon sink.

Global research and development Wolfgang Dienemann said “With ReConcrete-360°, we have succeeded in developing a limestone substitute from demolished concrete that also allows us to use the carbon-containing exhaust gases from cement production. A small revolution with a big impact: In Germany alone, the CO₂ savings potential of this process is 10Mt/yr. The IKU award underlines that we can be proud of our pioneering innovation.”
