Ultra-low carbon concrete
project underway
A pioneering project to boost the take-up of ultra-low carbon concrete in civil engineering and construction is underway.
Jackson Civil Engineering is a partner on the DULCET (Durable low carbon reinforced concrete for challenging environments) project, which aims to develop and prove the performance of a new reinforced Cemfree concrete range for use in aggressive environments such as salt water and highways.
The venture is being joint-funded by Innovate UK, the United Kingdom's innovation agency, which provides money and support to organisations to make new products and services.
Key to achieving this is the use of low carbon Cemfree concrete as well as basalt fibre, instead of steel to reinforce the concrete, as it is less corrosive and has a much lower carbon footprint.
Other partners on the project are the makers of Cemfree, DB Group; BasTech UK (BTUK), which manufactures the basalt rebar; pre-cast concrete makers Poundfield Precast and Building Research Establishment (BRE), which carries out independent research to improve the built environment
The low carbon reinforced specimens were recently poured at Poundfield’s facilities at Creeting St Peter near Ipswich where consultants from BRE oversaw the process.
Once cured, the blocks will be sent to BRE’s research laboratories near Watford for a series of tests.

'We have come a long way with the development of low carbon reinforced concrete – the challenge now is to give designers the confidence to specify the products in schemes on the ground. '
