Ultrafine grinding of fly ash with grinding aids: Impact

2015-3-1  In the ultrafine grinding process of fly ash, the network structure would be destroyed by mechanical force, resulting in the breaks of chemical bonds such as Si O Si, Al O Al and Si O Al. Thus the polymerization state of fly ash would be depolymerize from high polymeric structure to low polymeric structure.

Ultrafine grinding of fly ash with grinding aids: Impact

This paper presents the ultrafine grinding performance of fly ash with grinding aids (GA) and effect of GA on the particle characteristics, pozzolanic reaction degree of ultrafine fly ash (UFFA) and properties of blended cement containing UFFA.
