Concrete is reinforced by the addition of bare or coated steel reinforcing bars (rebar), which are usually formed into a gridlike pattern prior to pouring the concrete. The reinforcing steel helps the concrete resist tensile stresses that would otherwise tend...

The inclusion of steel reinforcing bars within the masonry gives a great increase in its ability to resist tensile and shear forces. The reinforcing bars are surrounded by grout or mortar to form a composite element. The grout...
