Carbonation and porosity of mortar specimens with pozzolanic and hydraulic cement admixtures
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.
