Concrete has rather superior compressive strength, but Substantially reduced tensile power.[106] Thus, it is generally reinforced with elements which are solid in rigidity (typically steel). The elasticity of concrete is fairly frequent at low anxiety stages but begins reducing at larger anxiety stages as matrix cracking develops.
In reinforced concrete, the tensile power of steel and also the compressional energy of concrete render a member effective at sustaining heavy stresses of all kinds in excess of substantial spans. The fluidity of the concrete mix can make it attainable to placement the steel at or close to the point where by the greatest anxiety is anticipated.
