Tilt-Up Concrete Construction
Concrete
Placement
Before placing
concrete for Tilt-Up panels, clean the base slab. Use compressed air
to blow away dirt, leaves, and other loose debris. Also, remove any
standing water on the slab.
Concrete placement methods for Tilt-Up panels are the same as those
for floor slabs. Since the panels are structural members, make sure
the concrete mix meets specifications. Direct chute placement is the
most economical method, but pumping and bucket placement also work.
Consolidate the concrete to ensure good flow around the reinforcing
steel. A trowel finish is suitable for most projects.
As with other types of concrete construction, plan for the
unexpected. If the weather will be cold, have insulation blankets
ready. If it looks like rain, delay the pour or have a suitable
covering material available. Provisions should be made to block off
a pour if a concrete truck breaks down or gets stuck in traffic. On
hot or windy days, be prepared to cure the panels by water misting
or by applying a suitable curing compound.
