Academy of Young Scientists

At the initiative of the Board and Members of the Section of Building Materials Engineering, Committee of Civil Engineering - Polish Academy of Sciences, on June 15-16, 2023, our #MSAGroup research team hosted, within the framework of the Academy of Young Scientists, representatives of a number of renowned research units from all over Poland (AGH, Instytut Techniki Budowlanej, Wrocław University of Science and Technology and Cracow, Kielce, Opole, Rzeszów, Silesian and Warsaw Universities of Technology). During the theoretical part of the workshop entitled: "Methods for studying the chemical and mineral composition of cement hydration products," participants had the opportunity to listen to lectures given by Professor Zbigniew Giergiczny and Professor Wojciech Franus. During these lectures, workshop participants gained expert knowledge about cement, its components, the hydration process and aspects related to standardization and application in construction. In addition, they were introduced to the possibilities of studying hydration products from both chemical and phase analysis perspectives. Theoretical knowledge gained was applied in the laboratory part of the workshop. The Young Scientists had the opportunity to learn the principles of sample preparation, analysis and interpretation of results, using three research methods: X-ray fluorescence spectrometry (XRF), X-ray diffraction (XRD) and scanning electron microscopy with chemical composition microanalysis (SEM-EDS). The workshop provided an excellent opportunity to exchange knowledge between scientists from different parts of Poland and to present the research capabilities of our laboratory. We would like to thank all participants for their participation in the workshop.

Two weeks of building scientific cooperation are behind us

In the period from May 14 to 28, 2023, members of our MSAGroup research team (Joanna Fonczyk, Joanna Styczeń, Martyna Janek and Wojtek Franus) were on research visits, which included scientific cooperation with two research groups: Concrete Research Group headed by Aleksandra Radlinska and Structural Science Group headed by Olaf Borkiewicz. During our week-long stay at Penn State University, we had the opportunity to present two papers titled. "Influence of zeolite framework on the cement hydration process" and "Microbially Induced Carbonates Precipitation (MICP) in self-healing cement composites",as well as learn about the technique of 3D printing large-scale concrete architectural elements and the research potential of this University. Amazing impression!

Then, after an almost 11-hour car trip, we arrived at Argonne National Laboratory, where, under the supervision of Kamilla Wiaderek and Olaf Borkiewicz, we conducted pilot experiments on the level of ordering of the C-S-H structure depending on the contribution of the pozzolanic additive (in our case, it was the allite-synthetic zeolite system) during the initial period of hydration, and phase changes in carbonate minerals during the process of self-healing cracks and cracks in concrete using the potential of bacteria. Olu, Kamilo, Olafie thank you for your hospitality and great atmosphere during our visit!
