ACI Showcases Solidia as Emerging Technology for Civil Infrastructure
Solidia Technologies’ novel utilization of carbon dioxide in concrete curing was featured as a leading emerging technology in civil infrastructure during the American Concrete Institute Fall 2015 Convention taking place this week 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 percent 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 ton of cement during the curing process.
