Cement Composites Biodeterioration by Acidithiobacillus Thiooxidans
WSEAS TRANSACTIONS ON ENVIRONMENT AND DEVELOPMENTThe focus of this work was to study the biodeterioration of special cement composites by sulfur-oxidizing bacteria Acidithiobacillus thiooxidans. The laboratory prepared cement composites that contained the selected additives - silica fume (a secondary raw material) and zeolite (a natural raw material), as partial replacements for the binder. The tests
