Climate effects of carbonation
The uptake of CO2 in concrete also affects the net emissions of CO2 from the use of concrete in society and thus also the impact of concrete use on greenhouse gases and its climate effects. It is therefore important to understand and to take into account both the technical aspects of carbonation and its climate effects.
Carbonation of concrete
Carbonation of concrete is the chemical reaction between carbon dioxide in the air and calcium hydroxide and hydrated calcium silicate in the concrete to give mainly carbonates.
Calculation of CO2 uptake in concrete
Calculations of CO2 uptake in concrete are complex and include both chemical and physical processes.
Two calculation models
