Significance of fineness of pozzolans in determining pozzolanic reactivity
CEMENTThis paper presents the quantification of the pozzolanic reactivity of pozzolans examined in terms of compressive strength, bound water and electrical resistivity. The pozzolans studied included natural pozzolans, glass pozzolans and fly ash that were ground to four fineness levels or median particle sizes (d50) of approximately 3, 5, 10 and 15 µm ...
