Since A706 rebar inherently meets the requirements of A615, all W bars should also be accepted as dual grade. Future A706 and A615 specification revisions may permit reinforcement bars with only a ...

Common construction methods are the use of control joints typically spaced at 15 or 18 feet, extensive rebar reinforcement, post-tensioning slab designs, and pour strips. These materials and ...

Concrete's greatest weakness is its tensile strength, which can be less than 10% of its compressive strength. So, we often reinforce it to create a composite material strong against all types of ...

The carbon fiber is woven into a mesh, or as a composite material that mimics existing rebar structures. These two types of reinforcement can be combined in a composite to produce a concrete ...
