2021-11-12 Concrete has tremendous compressive strength, so to make it sturdier, engineers add steel bars inside concrete structures. This adds to the tensile strength of the concrete structure to make it a strapping, robust building. Notice the steel rods. They impart tensile strength to the concrete structure.
