CO2-cured low-emissions cement
Low emission process for cement and concrete production
01.
Identification
Solidia Cement™ and Solidia Concrete™ are two features of a process that reduces the carbon footprint associated with cement by up to 70%.
The solution consists of the production of a low-lime, calcium silicate cement (CSC) as a replacement for ordinary Portland cement (OPC), and the curation of concrete made with CSC by it reacting with CO2 rather than H2O. CSC can be made in existing cement kilns, consumes less limestone and requires less energy than OPC all while reducing CO2 emissions from the kiln by 30 to 40%. When CSC-based concrete is cured with CO2, it costs less to produced, cures in less than 24 hours versus the traditional 28 days and has a higher durability than its OPC counterparts. Together, the low-lime cement/CO2-cured concrete technologies offer the potential to reduce the carbon footprint of cement and concrete and the water used to form concrete products can be reclaimed and recycled.

Implementation Stories
CO2-cured low-emissions cement by Solidia Technologies
Implemented by Elsmere Fire Company in Elsmere (United States) in 2019
Elsmere Fire Company, a fire department located in Delaware, commissioned a contractor (Next Level Hardscaping) for the installation of a new surface of 1000 square foot in front of their fire station. They teamed up with a paver manufac- turer – EP Henry – and Solidia to deliver the infrastructure with low carbon cement. At first, the installation of 4,806 pavers (= 8,900 kg of material) was also chosen as a water management paving system designed to address flooding issues in Delaware.
Result
2.2 metric t of co2 avoided
