ACI showcases Solidia Technologies’ CO2-curing innovations

Solidia Technologies’ utilisation of carbon dioxide in concrete curing was featured as a leading emerging technology in civil infrastructure during the American Concrete Institute (ACI) Fall 2015 Convention taking place in Denver.

Solidia Cement™, which is silicate-based and has a low-calcium content, gains strength through carbonation instead of hydration. Presenting findings of ‘CO2-Cured Concrete based on Calcium Silicate Cement (CSC)’, Solidia Technologies Principal Scientist Sada Sahu, Ph.D., explained that, when compared to Ordinary Portland Cement (OPC), 30% less CO2 is emitted during the production of Solidia Cement. Additionally, Solidia Cement-based concrete (CSC) can consume up to 300 kg of CO2 per t of cement during the curing process.

For the second consecutive year, ACI Foundation’s Strategic Development Council (SDC) showcased Solidia as a leading innovator in the field. 

Commenting on the panel discussion, Dr. Ravikumar said, “Sustainable solutions are so important to this industry, since cement and concrete production accounts for up to five percent of global CO2 emissions. We discussed ways to reduce energy consumption, the use of various SCM's, or an alternative fuel source to make cement, but it is clear Solidia is the only all-encompassing solution.”

Currently in commercialisation for large- and small-scale applications, Solidia’s additional R&D collaborators include LafargeHolcim, CDS Group, DOE’s National Energy Technology Laboratory, the EPA, Rutgers University, Purdue University,Ohio University, and the University of South Florida.
