Study on Calcium Nitrate impact on Carbonation of Concrete

Calcium Nitrate is a well-established concrete admixture since the 1980s and mostly used as setting accelerator. Additional effects have been documented such as compressive strength enhancement and several studies indicate reinforcement corrosion mitigation. Due to the impact on the distribution of the porosity it was suspected that Calcium Nitrate might influence the carbonation process, too.
