4) Return to the plant and build
retaining blocks or other precast
concrete structures with the
rejected
concrete.
While this is a good way to dispose of unwant-
ed concrete, the revenue from these struc-
tures is much less than the actual cost of the
concrete. If it were profi table, most ready mix
companies would already be in the precast
business.
Fritz-Pak offers a solution: the best option is
to correct potentially rejected loads by add-
ing appropriate admixtures at the job site so
they meet specifi cations. Fritz-Pak admixtures
are pre-measured powders packed in easy-to-
use water soluble bags. They are added direct-
ly to the ready mix truck and mixed for 5-10
minutes on site. These products can:
1) Correct air content
2) Increase slump without adding water
3) Decrease slump for proper placement
4) Accelerate the set time without chlorides
5) Retard set time
6) Improve the pumpability of concrete
The cost of correcting a load in this way can
be as little as $0.35 per yard!
The Fritz-Pak line has been successfully used
by ready mix producers for nearly 20 years.
Those companies who carry Fritz-Pak on their
trucks are in the best position to make quick
inexpensive corrections to salvage otherwise
rejected loads, making them more competi-
tive in an increasingly tough market.
In the case of unexpectedly leftover concrete,
Fritz-Pak retarders carried on the truck can be
added whenever needed to extend the life of
the concrete. It can then be safely diverted to
another site, returned to the plant for proper
disposal, or even for rebatching.
In the following pages, we give a brief over-
view of the applications and use of Fritz-Pak's
products most useful to ready mix producers.
More information about all of these may be
found in our product brochures and Product
Bulletins. You can fi nd all this information on
