Wiktor, V. (author), Jonkers, H.M. (author)Biodeposition, a method by which calcium carbonate (CaCO3) precipitation is induced by bacteria, has been proposed as an interesting approach to protect building materials. The liquid-based system presented in this paper aims at the sealing of cracks and decrease of the porosity due to the production of a calcium-based biomineral. In this system...conference paper 2015

Wiktor, V.A.C. (author), Jonkers, H.M. (author)This paper presents the field performance in a parking garage of the recently developed bacteria-based repair system for concrete. This liquid-based repair system aims at the sealing of cracks and decrease of the porosity due to the production of a calcium-based biomineral. The system combines advantages of both a traditional repair system for...journal article 2015

Wiktor, V.A.C. (author), Jonkers, H.M. (author)This paper focuses particularly on the ageing of concrete due to micro-crack formation or freeze/thaw which results in an increased permeability of the concrete. The bacteria-based repair system presented in this paper aims at recovering the concrete permeability thanks to bacteria-induced calcium carbonate precipitation inside cracks/porosity....conference paper 2014

Sangadji, S. (author), Wiktor, V.A.C. (author), Jonkers, H.M. (author), Schlangen, H.E.J.G. (author)Bacteria induced calcite precipitation has been proven to be effective in making concrete structure self-healing. In Microlab TU Delft, the concept has been enhanced by developing a liquid bacteria-based concrete repair system. The solution contains calcite precipitating bacteria, nutrients and buffer compound which may demonstrate high...conference paper 2013
