For ultrafine fly ash mortar, the 28-day compressive strength of mortar shows an evident trend of first increase and then decrease with the increase of replacement ratio. Under the condition of ensuring the same compressive strength, upgraded finer fly ash can replace more cement, thus realizing energy saving and CO 2 emission reduction.

Feb 15, 2021  For 90F mortar, when fly ash replaces 30%~45% of cement, the compressive strength of 90F mortar is close to that of Control group, and higher replacement ratio will cause a decrease of compressive strength. For 60F mortar, this value is around 15%. For 40F mortar, there is no increasing tendency.
