May 15, 2007· That depends on the kind of concrete. There are different types and different figures. One way - take the density of concrete (2,300 kg/m^3 from the Physics Factbook), the CO2 to make cement (0.8 kg CO2/kg cement), the cement in concrete (10% from cement). This makes a figure of around 100 million kg of CO2 in our nuclear plant.
