Carbon dioxide is non-toxic greenhouse gas emitted from sources as cement production. Concrete samples with different percentage of cement replacement by slag and also samples prepared according to standard recipe were prepared for the experiment. Sets of samples were exposed to aggressive environment (acid solution and medium with bacteria Acidithiobacillus thiooxidans) during 6 months. Quantities of calcium and silicon leached out into the liquid solution have been measured. Dissolved quantities were used for statistical analysis of trend of leaching and its influence on properties of concrete samples. Results point to the positive contribution of slag incorporation into concretes (exposed to chemical attack) and its important role in air pollution prevention by reduction of CO2 cement emissions.
