AAC Precast Floor Panels
General:
Please read the following instructions to insure proper handling and installation of Autoclaved Aerated Concrete (AAC). Damage may occur if AAC is moved or handled several times. If damage should occur to panels, the manufacture should be notified and the panel should be set aside until the repair or use be determined by the manufacture.If damaged to block should occure it should be trimmed and utilized to reduce job site waste.
For All AAC
Construction Products
Deliver only an amount of material that can readily be installed.
Unload panels using pallet forks (either forklift, nylon straps, slings or pallet fork on a crane cable). Consult your OSHA safety manual for "rigging" or other safety considerations.
Storage areas should be accessible to delivery trucks and convenient to material staging areas. If possible, drop-deliver the material right to the material staging areas.
Storage material should always be stored away from other construction activities on a flat-grade area that is not susceptible to standing water, erosion or settling.
Keep the material on pallets and out of mud until ready for installation.
Special Considerations For
Panel Construction
As with most precast concrete products, the panels should be set directly from the delivery trailer, if permissible.
If the materials cannot be set directly from the delivery trailers, deliver only an amount of material that can be readily installed.
Do not "shake-out" stored materials until they are ready to be installed. Excessive handling may cause damage. Set delivery schedule to match exactly the erection sequence.
Most chipped corners and edges can be repaired. If any reinforcing is visible, contact an authorized AAC representative.
All damage must be repaired using an approved structural-grade AAC patching compound developed specifically for AAC products.
Most cracked planks or panels are usable, but contact an authorized AAC representative when cracks continue completely through the piece.
Stored or staged materials should always be set on flat, load-bearing, stable grade on pallets or dunnage.
