What is the wire used to secure concrete blocks commonly called?

• A. Anchor Wire
• B. Rebar
• C. Tie Wire
• D. Sill Wire

Answer: (C)

The wire used to secure concrete blocks is called tie wire because its job is to bind or tie the masonry units together during construction, helping keep blocks aligned and in place until the mortar cures. It’s a soft, easily twisted steel wire that you wrap around blocks or through joints to hold the wall steady while work continues. This is different from reinforcing material like rebar, which provides structural strength, and from terms like anchor wire or sill wire, which aren’t the standard name for this binding purpose. Tie wire directly reflects its function of tying the blocks together.
