Carbon Sequestration and Decarbonization Technologies for Sustainable Cement and Concrete

In the global effort to combat climate change, the cement and concrete industry has been identified as a key decarbonization target owing to accounting for approximately 8% of CO2 emissions. Avenues for decarbonizing this sector include energy efficiency improvements, reuse/recycling, and carbon capture utilization and storage. This project consists of two sub-projects focused on different avenues to decarbonization. The first sub-project focuses on development of a ground recycled post-consumer glass alternative supplementary cementitious material to be treated with CO2 before use as a replacement for Portland cement. The second sub-project focuses on development of a novel CO2 stable foam for use as a component in cellular concrete. Cellular concrete is a non-structural form of concrete that does not use aggregate but rather air bubbles to produce a low density product. Replacing air bubbles with CO2 bubbles provide a potential avenue towards carbon sequestration in this niche deployment of concrete.
