MIT Publishes Research Brief on Net-Zero Carbon Concrete in U.S. Pavements
The MIT Concrete Sustainability Hub (CSH) has released a research brief that presents pathways to net-zero concrete pavements by 2050. The three-page brief, written by Dr. Hessam AzariJafari of the CSH describes the need to address strategies and methods for offsetting and reducing embodied greenhouse gas emissions in concrete pavements.
A few of the key messages include:
Concrete mixtures with zero embodied carbon can be attained using the simultaneous benefits of reduction, replacement, reuse, recycling, and CO2 sequestration.
Technical and economic barriers, as well as market acceptance, should be considered in future work to investigate their feasibility in different regions.
The order of implementation will determine the contribution of each attribute to the total GHG savings.
