- •
Alkalis in fly-ash acts as a concrete durability key parameter.
- •
Influence of free CaO, reactive silica and residue fineness on alkalis content was assessed.
- •
Alkalis content in fly-ash mainly depends on reactive silica amount.
- •
Increasing reactive silica will increase alkalis content.
- •
Alkalis changes in function of free CaO, reactive silica and fineness was examined.
