CHRYSO collaborates with Solidia Technologies on low carbon concrete

CHRYSO, a leader in construction chemicals, has announced its partnership with Solidia Technologies, a start-up inventor of revolutionary technology for green cement and concrete. The two companies will collaborate to improve the sustainability performance and material properties of Solidia® ultra-low CO2 concrete through their combined chemical expertise.

The partnership is underpinned by a long-term commitment from both companies to making sustainable solutions accessible to cement and concrete producers worldwide.

Solidia sustainable technology is already available in the precast market and is used for non-reinforced concrete elements. Solidia’s unique technologies are based on a cement chemistry that can be produced at lower energies, significantly lowering carbon emissions, without hydrating but carbonating by injection of CO2 into fresh concrete. Combined, Solidia’s processes lower the carbon footprint of concrete by up to 70%, while reducing water and energy consumption. They also improve the performance and durability of concrete, which are further enhanced with a new, sophisticated admixture solution.

CHRYSO draws on a solid knowledge of sustainable building materials. For more than 10 years, the company has been developing admixture solutions that allow the intensive use of alternative binders without compromising material performance.

“The development of innovative admixture solutions adapted to Solidia’s new binder, boosting the final properties of concrete, is one of our R&D works in progress. This will enable higher strengths, an improved finish of the fresh concrete, and the optimisation of the curing process. Together with Solidia, we will scale the use of low CO2 concrete, helping manufacturers produce high quality precast elements,” declared Jean Mascaro, Concrete BU director of CHRYSO.

Tom Schuler, President and CEO of Solidia Technologies, said: “Incorporating CHRYSO’s exclusive water-reducing admixtures adapted to the specific chemistry of Solidia Concrete, will further reduce water consumption in the curing process.”

A key objective for the start-up is to improve cement and concrete production and performance while enhancing its environmental impact. Tom Schuler added: “By cutting energy consumption during the curing process, CHRYSO will help us achieve our ambitions and reach higher levels of performance.”

This partnership paves the way for upcoming advances in CO2 footprint reduction and new developments in sustainable chemistry. The deployment of new ultra-low CO2 concrete will accelerate the decarbonisation of the construction industry.
