Paris/France – After a successful pilot phase, Air Liquide renews its partnership with Solidia Technologies, a developer of solutions to reduce the environmental footprint of precast concrete manufacturing.

During the pilot phase initiated in 2016, a joint team of Air Liquide and Solidia Technologies experts have industrialised the innovative solution Solidia Concrete, which uses carbon dioxide (CO2) to cure concrete. The combination of the consumption of CO2 during curing, and lowered carbon emissions achieved in the production of low-energy Solidia Cement that is used to bind the concrete, results in an up to 70 % reduced carbon footprint compared to traditional concrete.

As part of this worldwide partnership, Air Liquide is Solidia's preferred supplier of CO2 and the equipment used for its injection. In the United States, where sales of Solidia Concrete have been launched, Airgas, an Air Liquide company, supplies the carbon dioxide recovered and purified from CO2 emitted by other industries.

Specialist Book „Heat Transfer Technique“The comprehensive standard work „Heat Transfer Technique“ offers not only a detailed and well-founded presentation of the basics of heat transfer technique, but also shows the latest state of the art and the latest regulations in the use of organic fluids. Thematically, the book is rounded off with an overview of property data of organic heat transfer fluids as well as many use cases from practical experience.

Matthieu Giard, Vice President and Executive Committee Member of Air Liquide Group, supervising the Industrial Merchant business line commented: “Based on an innovative use of CO2, this technology represents a particularly interesting solution to reduce the carbon footprint of precast concrete.”

Tom Schuler, President and CEO of Solidia Technologies, added: “Air Liquide’s expertise has been a critical element in the development of our CO2 curing technology and the delivery of higher performance, lower environmental footprint concrete. We look forward to our continued collaboration with Air Liquide as we work to develop new products, enter additional markets, and offer new sustainable solutions for the entire 1 trillion dollar global concrete market.”
