Due to an unfortunate turn of events the below note was not included in the paper but however should have been and therefore is to be regarded as part of the paper by the reader.

This paper corresponds to the 2014 Robert L’Hermite Medal lecture of Dr. Alexandra Bertron at the 2014 RILEM Annual Week in Sao Paulo, Brazil. She was awarded the medal as “She stood out due to her consistent research output, active participation and leadership in RILEM, international exchanges and the high quality of her work. Her research activities, performed at the Laboratory for Durability of Materials and Constructions (LMDC, U. Toulouse), mainly concern the interactions between cementitious matrices, organic matter and microorganisms both in aqueous and air media. Her research works focus on the investigation and the understanding of the phenomenology of these interactions in order to improve the durability and the quality of concrete construction”.
