Juho Yliniemi

Juho is an Associate Professor in the Fibre and Particle Engineering Research Unit and Group leader of Materials chemistry of inorganic side streams and applications-team.

He has over 10-year research experience on industrial inorganic sidestreams and alkaline activated materials which are commonly called as geopolymers. He has also founded a company (www.kekogeopolymeerit.fi) based on the research.

The research focus of his team are:

-Advanced characterization of inorganic side streams
-Low-CO2 cement binder chemistry
-Dissolution, precipitation, and hydration reactions
-Cement admixtures
-Metal-ligand complexes
-Solid surface-liquid interface reactions
-Performance of low-CO2 cementitious materials
-Fresh and hardened properties of mortars
Characterization of hardened cements in nano- and microscale

Research interests

  • Alkali-activated materials; Materials chemistry of cement; Dissolution of silicates;
