Research & grants
General research interests
My primary research interests are in materials characterization (mainly cementitious composites, fly-ash, FRC, HPC, novel
metallic structures) using advanced experimental techniques, related
microstructure description, multi-scale modeling and applications of novel
nano/micro-scale materials and modifications to increase structural
integrity and durability. Since 1999, I participated in
several grant projects as PI or co-PI sponsored mainly by the Czech Science
Foundation (CSF), and Ministry of Education and Ministry of Culture of the
Czech Republic.
Currently working on
Nanomechanics, nanoindentation, nanoparticle treatments to structural materials,
electromigration, chloride transport and resistance, rheology of fresh
concrete, formwork pressures.
