biogenic acid attack result in an increase of the porosity and changes in the pore structure of
the building materials. The impact of certain physicochemical concrete/mortar parameters
such as cement chemistry, water/binder (w/b) ratio, porosity and fluid permeability of
cementitious materials has been recognized from a material sciences perspective. In this work
the durability of cement composite made with blast furnace slag exposed to sulphur oxidizing
bacteria A. thiooxidans during the period of 12 months was investigated. Leaching of calcium
and silicon ions, water absorbability and porosity of the slag based composite using X-ray
computed tomography was evaluated.Workplace Institute of Geonics Contact Lucie Gurková, lucie.gurkova@ugn.cas.cz, Tel.: 596 979 354 Year of Publishing 2019 Electronic address https://iopscience.iop.org/article/10.1088/1757-899X/385/1/012052/meta
