NRRA: Use of Carbon Dioxide for Sustainable and Resilient Concrete Pavements
It is becoming increasingly apparent that it is necessary to explore alternative options for cement and concrete production used in public infrastructure to reduce carbon footprint. One possible process is to bubble CO2 in the fresh concrete during production to sequester CO2 and possibly to reduce cement content in the concrete without compromising system performance. This approach also has the possibility of reducing the susceptibility to oxychloride formation as demonstrated in pilot work conducted by this team. Concrete with reduced cement content will exhibit reduced shrinkage reducing the risk of early age cracking. Confirming these benefits would be a breakthrough in simultaneously reducing the CO2 footprint while enhancing concrete performance. The goal of this research is to address the questions of how much CO2 is sequestered using CarbonCure technology, and what are the effects on the performance of the pavement? The work will also include an assessment of the reduction of the CO2 footprint compared to control mixtures based on determining the amount of CO2 bound in the mixture as well as potential changes in maintenance needs of the pavement over the life of the pavement under traffic and environmental exposure.
