reinforced concrete, concrete during which steel is embedded in such a manner which the two elements act jointly in resisting forces. The reinforcing steel—rods, bars, or mesh—absorbs the tensile, shear, and often the compressive stresses inside a concrete composition. Basic concrete doesn't quickly withstand tensile and shear stresses a result of wind, earthquakes, vibrations, and other forces which is for that reason unsuitable for most structural programs.

Concrete has relatively high compressive energy, but A great deal reduce tensile toughness.[106] As a result, it is normally reinforced with resources which might be sturdy in pressure (typically steel). The elasticity of concrete is comparatively continuous at lower anxiety ranges but starts off decreasing at bigger strain stages as matrix cracking develops.

Polymer concretes are mixtures of aggregate and any of various polymers and could be reinforced. The cement is costlier than lime-centered cements, but polymer concretes Yet have pros; they may have sizeable tensile strength even without reinforcement, and they're mainly impervious to drinking water.
