Martinez et al. tested three different Roman concrete recipes with varying slaked lime-to-pozzolan ratios (1:2, 1:3, and 1:4), and assessed greenhouse gas and air emissions for each production stage based on known Roman construction practices. The results surprised the scientists. Per volume of concrete, the production process for Roman concrete ended up emitting as much and, in some cases, more CO2 than modern formulations.
