The effect of the addition of lignite fly ash, natural greek pozzolan and blastfurnace slag to ordinary portland cement on the carbonation of mortar specimens was studied in a programme of long-term exposure to the atmosphere in relation to the evolution of their porous structure. Additions of 4%, 15% and 30% or 50% of the admixtures to the cement were tested. The carbonation depth and the specific pore volume of the cover were measured. The additions of 4% pozzolan, and 4% and 15% fly ash, and 4% and 15% slag did not influence the porosity and the carbonation of the specimens compared to reference specimens without admixtures. Higher additions resulted in an increase of the above parameters. © 1994. (EN)
