Tests have been carried out to investigate the way in which carbon dioxide gas reacts with hardened portland cement in mortar. The influence of such factors as evoporable and nonevaporable water on this reaction was studied and the effect of different storage conditions on the shrinkage and the strength of the mortar is reported. It was found that the absorption of carbon dioxide IQ-creases in the presence of evaporable water. The carbon dioxide thus taken up reacts with the lime compounds; some carbon dioxide is bound as calcium carbonate but some is held by some less powerful bond.
