Cement giant LafargeHolcim and cement-and-concrete technology start-up Solidia Technologies are to supply US precast concrete paving slab manufacturer EP Henry with its low-CO2 cement, in what they claim is a commercial breakthrough.
In development since 2013, Solidia Concrete is produced at lower temperatures and through a different chemical reaction that generates less CO2.
Solidia Cement also hardens by adding CO2 instead of water in a patented curing process that reduces the overall carbon footprint by up to 70% – achieved with a 40% reduction in carbon emissions and a 30% reduction in energy during production.
