Cover Story: Pervious portland cement concrete is both energy- and carbon-intensive to manufacture. Like normal concrete, however, some of the initial CO2 emissions associated with its manufacture can be sequestered through natural carbonation. In this work, we present the formulation and application of a theoretical model for estimating the CO2 sequestration potential of pervious concrete. We conservatively estimate that natural carbonation can recover up to 12% of initial CO2 emissions and that the CO2 sequestration potential is maximized for pervious concretes with lower water-to-cement ratios, higher compressive strengths, lower porosities, and lower hydraulic conductivities. We also show that mixtures with maximum CO2 sequestration potential emit more CO2 from a net-emissions perspective, despite their enhanced in situ CO2 sequestration potential. View this paper.
