Elijah Adesanya


Doctoral Researcher
Process Engineering


Elijah is a Doctoral researcher at Fiber and Particle Engineering Research Unit. He started working in the unit as an Intern in 2014 after which he proceeded with his Master thesis in 2015 in the same unit. 

After graduation in 2015, he started as a Doctoral researcher working on the valorisation of industrial residues in alkali activated materials and in hydraulic binder as an alternative to Portland cement.

Thesis supervisions

Alkali activation of Fayalite slag (Co-Supervision)
  • # In this thesis, alkali activation of fayalite slag was investigated. The slag utilized is a by-product from nickel production. The activation of which resulted in the formation of an inorganic polymer binder of acceptable mechanical properties.
