Prediction model of compressive strength development of fly-ash
Fig. 1 shows the compressive strength development over time. Without fly ash, PL, the rate of strength development significantly decreased after an age of 28 days. When fly ash was added in place of part of cement, IN, the early strength was lower than that of the non-fly-ash concrete, but strength gains continued for a long time.
