The Use of Alkaliphilic Bacteria-based Repair Solution for Porous Network Concrete Healing MechanismSangadji, S. (author), Wiktor, V.A.C. (author), Jonkers, H.M. (author), Schlangen, E. (author)Bacteria induced calcium carbonate precipitation based on metabolic conversion of nutrients has been acknowledged for having potentials in self-healing cement-based materials. Recent studies have shown the development of bacteria-based repair solution (liquid) for concrete surface repair. This article demonstrates the feasible application of...conference paper 2017

Sangadji, S. (author)The high energy consumption, its corresponding emission of CO2 and financial losses due to premature failure are the pressing sustainability issues which must be tackled by the concrete infrastructure industry. Enhancement of concrete materials and durability of structures (designing new infrastructures for longer service life) is one solution...doctoral thesis 2015

Sangadji, S. (author), Schlangen, H.E.J.G. (author)To repair concrete cracks in difficult or dangerous conditions such as underground structures or hazardous liquid containers, self healing mechanism is a promising alternative method. This research aims to imitate the bone self healing process by putting porous concrete internally in the concrete structure to create a porous network similar to ...journal article 2013

Wiktor, V. (author), Sangadji, S. (author), Jonkers, H.M. (author), Schlangen, H.E.J.G. (author)Bacterially induced calcium carbonate precipitation has received considerable attention for its potential application in enforcing or repairing construction material. The mechanism of bacterially mediated calcite precipitation in those studies is primarily based on the enzymatic hydrolysis of urea. Besides calcite precipitation, this reaction...conference paper 2013

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

Schlangen, H.E.J.G. (author), Sangadji, S. (author)Infrastructures cover a very broad spectrum of different materials. This paper focuses on civil engineering structures, concrete and asphalt in particular. The public demand for such infrastructures is high level of service and performance, high durability and minimum negative ecological impact. New emerging self healing materials science...journal article 2013
