Aug 29, 2019 Reinforce with Rebar. Concrete needs reinforcement for added strength and crack resistance. Its well worth the small additional cost and labor to install 12-in. rebar steel reinforcing bar. Youll find rebar at home centers and at suppliers of concrete and masonry products in 20-ft. lengths.
Design of Reinforced concrete walls are in many ways like columns.. They support vertical loads and are vulnerable to minor axis bending. They often act as primary elements of a structures lateral stability systems and by doing so are subjected to high in-plane bending forces.
Building walls using hollow concrete block is an economical means to creating a structure. However, hollow concrete block walls are not structurally very strong and will not resist the flexural stress that a wall is subjected to, causing them to collapse easily.
Concrete also can crack due to changes in temperature or unevenly distributed weight or stress. When pouring concrete for driveways, foundations, or floors, two common ways to reinforce concrete are to use wire mesh or fibers. Wire Mesh.

Another recent development in pouring concrete structures such as slabs is to add polypropylene fibers to the concrete, which then form a three-dimensional mesh to reinforce the slab. The chemical-mechanical bond the fibers form with the concrete can be superior, depending on what the structure is used for, to rebar reinforcement.
Concrete is an attractive building material because of its relatively low cost, environmental stability, and high compressive strength. Due to its inherent low tensile strength, however, concrete requires reinforcement in applications where significant tensile stresses will be realized in order to maximize its load-carrying capability and improve its toughness.
