Note: J₁ represents the water maintenance of without dosage of admixture specimen with a base content of 0.60 in water at 80 degrees C; J₂ represents the water maintenance of without dosage of admixture specimen with a base content of 0.90 in water at 80 degrees C; the FA-1-0 experimental piece with a base content of 0.60 without dosage of admixture maintained in an alkali solution of 80 degrees C 1 mol/L; the FA-2-0 experimental piece with a base content of 0.90 without dosage of admixture maintained in an alkali solution of 80 degrees C 1 mol/L; the FA-1-20 experimental piece with a base content of 0.60, and the amount of dosage of admixture is 20% without dosage of admixture maintained in an alkali solution of 80 degrees C 1 mol/L; other specimen numbers are similar to the above.
