j. Mix Setting Chart.
CAUTION
The filled-out chart is only an example.
Do not use it to make concrete.
Whenever admixtures are
used, the amount of solution being added to the mixture in gallons per minute must be subtracted
from the water settings found in water settings calculations.
(1) Determine change in water settings when using admixture in the following manner
(a) If the hi-flow admix system is being used divide answer (C, fig 2-6) by four to get gallons per minute.

.525 = .5
÷
Qts Per Minute
Qts/Gal
Gal Per Minute
(b) If the low-flow admix system is being used divide answer (E, fig 2-9) by 128 to get gallons per minute.
12 6 (E, Fig.4-9)

0.98 = 0.1
÷
=
Ounces Per Minute
Ounces/Gal
Gal Per Minute
(c) Subtract either (1) or (2) or the total of both from either water setting (S or W, fig. 2-2).
