This usual case appeared in water and fog curing at both 20[degrees]C and 40[degrees]C in which the CA concrete had 52 MPa at 91 days (Table 5) that was the highest strength in this experiment.
Table 6 shows the percentage difference in compressive strength from the dry curing to those from the water curing (20[degrees]C, Standard Room) and fog curing (40[degrees]C, Hot Room), see Table 3.
The different strength ratios of dry curing to the water curing (20[degrees]C, Standard Room) and fog curing (40[degrees]C, Hot Room) are shown from Figure 4 and 5 according to the calculation results in Table 6.
To prove the self-curing effects, no testing was done for specimens by water and fog curing. Various degrees of tensile strength are found for the FA concrete specimens classified in four W/C ratios.
