b. General.
The Concrete-Mobile
®
mixer unit (hereafter referred to as the mixer) is a combination materials
transporter and concrete mixing plant. The special body is mounted on a model M919 truck chassis (see TM 9-2320-273-
10 for truck operating procedures).
The mixer carries sufficient unmixed material to produce fresh concrete in any quantity
up to 8 cubic yards (6.12 m
3
). The concrete is mixed at the site and since the unit has been precisely calibrated, mixes
can be produced that meet or exceed American Concrete Institute and American Association of State Highway and
Transportation Officials standards for design strength.
The unit can be used on an intermittent or continuous basis.
However, continuous operation is dependent on the availability of raw material at the site.
Some control settings for the
mix operations vary from truck to truck and from site to site.
The operating instructions in this manual identify which
settings vary. Your supervisor will provide you with the correct settings for your truck
