  • Concrete - Wikipedia

    Concrete is strong in compression, as the aggregate efficiently carries the compression load.However, it is weak in tension as the cement holding the aggregate in place can crack, allowing the structure to fail. Reinforced concrete adds either steel reinforcing bars, steel fibers, aramid fibers, carbon fibers, glass fibers, or plastic fibers to carry tensile loads.

  • Properties of concrete - Wikipedia

    Concrete has relatively high compressive strength (it doesn't crack under weight), but significantly lower tensile strength (it cracks when being pulled). The compressive strength is typically controlled with the ratio of water to cement when forming the concrete, and tensile strength is increased by additives, typically steel, to create reinforced concrete.
