Fig. 3: The A1-A3 GWP distribution for five concrete strength classes in the three U.S. regions with data highly saturated metropolitans.
From: Disparities in low-carbon concrete GWP at the metropolitan level in the United States
The relationship between GWP and five different concrete strength classes for the seven highly saturated metropolitans in the (a) Eastern, (b) Pacific Southwest, and (c) Pacific Northwest regions. We found that the five concrete compressive strength classes (p-values of 0.0294 and less) and three regions (p-values < 0.001) were statistically different from each other.
