Date: 5/1/2004. Abstract: The paper shows the influence of mineral additions (in form of fly ash, slag and ground limestone) replacing portland cement on the COz penetration rate of concretes manufactured at a given water-cementitious material ratio (w/cm). The results indicate that at a given w/cm there is an increase in the carbonation rate
