UK: Low Carbon Materials has participated in a trial project to build roads with lower embodied CO₂ emissions. The company supplied its ACLA carbon-negative aggregate for use in repairs to the M11 in Essex. National Highways has reported that CRH subsidiary Tarmac and Sweden-based construction firm Skanska also collaborated in the project.

National Highways’ research, development and innovation director Joanna White said "Solutions like this could have a real impact on our road to net zero carbon, so we are delighted that we have been able to accelerate the development of the product and get it on one of our roads for testing.”

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.”

UK: CRH subsidiary Tarmac has partnered with sensors specialist Converge to launch predictive AI-enhanced sensors for use in concrete mix optimisation. The equipment can reduce reliance on traditional cube testing, helping to shorten construction timelines. The sensors are available to all Tarmac customers.

Tarmac ready-mix concrete head Andrew Campling said "This new partnership with Converge means we can offer even more innovations to customers as part of our lower carbon CEVO concrete brand. Alongside other solutions, including our new online carbon calculator and the easy-to-use CEVO rating system, we're providing our customers with the tools to help them reduce carbon on construction projects."

Converge CEO Raphael Scheps said "The pairing of CEVO with Converge's sensors and AI technology is a perfect match for concrete decarbonisation. By packaging our technology with Tarmac's low embodied carbon mixes, contractors can build sustainably with the confidence that they're getting all the performance they need. We're proud to be partnering with Tarmac to offer leading AI solutions to the construction industry."

UK: CRH-subsidiary Tarmac has launched the new CEVO umbrella brand for its reduced-CO₂ concrete range. A colour-coded labelling system of strength and sustainability ratings also accompanies the new brand. The CEVO range will be the UK’s first to align entirely with the Institution of Civil Engineers (ICE)’s Low Carbon Concrete Routemap. Tarmac has also released a new carbon calculator, benchmarked against the Green Construction Board standard and calculated in accordance with PAS 2050 lifecycle assessment methodology. This includes a major update to the new BS8500 British concrete standard, which allows up to 20% limestone filler in concrete. The company has also developed an alkali-activated material (AACM) system in line with the new standard.

Tarmac’s head of readymix concrete performance Andrew Campling said "We've listened to our customers and made the process of accessing transparent data and procuring lower carbon concrete as simple as possible. Through the benchmarking, the options to deliver carbon savings are even easier to understand and measure - it is designed to be specification made simple."
