Concrete reinforcing bar placement ties?

Concrete reinforcing bar placement ties?

What are the requirements per ACI/CRSI for the type, material, and precribed placement for concrete reinforcing bar ties.  Is there a guide for the type of tie, for instance if it is steel, what gage and what spacing is required.  Can anyone provide a reference.  Does it address "bag ties" or automated rebar tying machines.

RE: Concrete reinforcing bar placement ties?

CRSI Manual of Standard Practice

Chapter 4 “Suggested Specifications for Reinforcing Steel”

E. Tie Wire:
1. Tie wire shale be 16.5 gauge or heaver, black annealed.
2. Epoxy-coated reinforcing bars shall be tied with plastic-coated or epoxy-coated steel wire; or other acceptable material.
3. Zinc-coated (galvanized) reinforcing bars shall be tied with zinc-coated steel wire, non-metallic-coated tie steel wire, or other acceptable material.

The CRSI book Placing Reinforcing Bars page 10-27 to 10-32 gives examples of different types of ties and why and when they are used.  There is also lots of other information concerning ties and wire.  There is no mention of the automatic tying machines.  In the field I have observed that experienced rod-busters can out tie a tying machine any day of week.
