Continuous Mixers:
Calibration of mobile mixers should be checked
every 100 yards for proper proportioning. The
yield will be required to be within tolerance
of 1.0% according to the following tests:
With the cement meter set at zero,
and all controls set for desired mix. Discharge
mix material into a square container measuring
36" x 36" 9". When the container has been filled,
and struck leve, the cement meter should read
an amount equal to the cement desired for 1/4
of a cubic yard.
The Mixers should have available
fluid tanks to separate water and latex as well
as any admixtures that will be used.
The Mixers should provide positive control of
the flow of water, latex, and admixtures into
the mixing chamber.
The Mixers should have provisions
to prevent foreign matter or objects from entering
the cement hopper during the loading process.
If citric acid is used in the
® Latex Modified Concrete (RSLMC), it
should be introduced to the auger through an on
board admixture tank.
