From April, 4 until May, 29 2019 a student of the Vilnius Gediminas Technical University (VGTU) doctoral study program , Ekaterina Karpova (Екатерина Карпова), is working in the Erasmus + program at the Faculty of Civil Engineering of the Brno University of Technology. As part of her PhD thesis and joint research, Ekaterina is interested in the impact of multi-layered carbon nanotubes (MWCNTs) on the properties of cement mortars and concretes with different types of superplasticizers. In the experimental work, she uses mainly scanning electron microscopy (SEM) and porosimetry (MIP) to elucidate the microstructure of developed materials with different doses of MWCNTs. It also focuses on the effect of suspension, with dispersed MWCNTs, on the resulting physical and mechanical properties of hardened mortars and the type of superplasticizer used on the development and course of hydration heat. Based on the evaluation of these results, the most suitable superplasticizer is selected for further testing.
