Abstract:
In order to satisfy the needs of concrete durability, it is important to know the deterioration mechanisms to which the material could be submitted. Among the different mechanisms of concrete deterioration, biodeterioration is one of the most recently observed in structures. Its study is complex and demands a multidisciplinary research which involves different disciplines. This paper addresses biodeterioration concepts, the mechanisms involved, and the impact on concrete phases (cement paste and aggregate). An example of aesthetic and microstructural impacts on the mortar phase of a normal concrete when it is colonised by the Cladosporium sphaerospermum fungus is presented.
