Title:
Bacterial Additives Improve the Water Resistance of Mortar 
Abstract:
The ingress of water into mortar and concrete is an ongoing problem which can reduce the lifetime of cementitious structures. Commonly used approaches that aim at preventing water ingress mainly employ an additional surface treatment after the casting process. Thus, they are time-consuming and make use of synthetic, nonsustainable additives. In contrast, it was shown recently that a biological material, i.e., a bacterial biofilm generated by B. subtilis 3610 bacteria, can be used as a bulk addit...    »
