MSAGroup

On 05-07.03.2025 Szymon Malinowski and Wojciech Franus represented MSAGroup - Materials/Synthesis/Application at the 16th technical seminar of the Association of Engineers and Technicians of Transportation of the Republic of Poland, Białystok branch “Current issues of traffic construction” in Mikołajki. Within the session “Contemporary climatic and environmental challenges in communication construction” we presented the results obtained during the INNOGLOBO project (INNOGLOBO/I/95/NZeolOx/2022) funded by the National Centre for Research and Development in lecture “Zeolite-oxide composites in the production of durable and environmentally friendly asphalt mixtures”. This seminar is one of the most important events in our conference calendar. A record 215 people attended this year's event, so attending the seminar is a great opportunity to present the research conducted at MSAGroup to a wide range of people involved in the Polish road construction industry. Thank you Marek Motylewicz for the invitation and see you next year!

Members of the MSAGroup - Materials/Synthesis/Application team (Joanna Fronczyk – SGGW, Martyna Janek, and Wojciech Franus, Lublin University of Technology) along with Barbara Gieroba and Anna Sroka-Bartnicka (Medical University of Lublin) have published a study on a method for healing cement composites using microbiologically induced carbonate precipitation (MICP). The article focuses on evaluating the ability of the ureolytic bacteria Bacillus subtilis to precipitate carbonates in the presence of different calcium and magnesium compounds through ureolytic and non-ureolytic pathways, as well as the impact of these processes on the self-healing of cracks in cement composites. The conducted analyses reveal how various factors—bacterial presence, composition of repair solutions, and the Ca/Mg ion ratio in the system—affect the carbonate precipitation process. The authors also highlight differences in the course and efficiency of this process under controlled conditions and within cement mortar environment.
The study has been published in the prestigious journal Composites Part B: Engineering (IF = 12.7). Read the full article here:
