Concrete reinforced with chicken wire or hardware cloth yields ferrocement, a versatile construction material. It can also be used to make the armature for a papier-mâché sculpture, when relatively high strength is needed.

Will concrete countertops crack?

A: Yes. Not always, but concrete countertops can develop hairline cracks. The cracks tend to be non-structural and result from the natural shrinkage of the concrete. However, some countertop cracks can be prevented.
