Biography

Jan specializes in the development, characterization, and evaluation of concrete mixtures, with focus on conventional, self-consolidating, high-performance, and other specialty concretes. He is an expert in rheology of cement-based materials, fresh concrete properties optimization and troubleshooting, and concrete pumpability. His technical work includes characterization of concrete air void system and assessment of freeze-thaw durability, implementation of new technologies in concrete mixture design, and use of novel test methods and characterization technique of construction materials. At CTLGroup, Jan’s main focus is on design, development and troubleshooting of concrete mixtures, solving construction-related issues, deployment of new products in the construction industry, and research & development.

Prior to joining CTLGroup, Jan was a research assistant at Kansas State University. While there, he conducted research projects focused on improving construction practices and durability of local infrastructure.
