•The CAP and PSD of FA were defined as the major factors effecting properties of mortar.•The mechanical and bond strength depend more on CAP of FA.•The PSD of FA effected the flow value and shrinkage of mortar more apparently. This article presents the effects of fly ash (FA) on the properties and m...
