- This paper presents the most frequently occurring cases of cement paste corrosion caused by living organisms. Concrete is exposed to the effects of corrosive factors. One of the factors which cause corrosion are living organisms. The key role is played by bacteria, algae, fungi, lichen. The role of microorganisms is essential in the destructive processes. The enzymes and metabolites secreted by microorganisms contribute to the destruction of the material by dissolution, hydrolysis, crystallization of the products of corrosion. Also, the settlement of microorganisms on the surface of a material, the biofilm effect, may lead to the processes of destruction.
