concrete

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, glass fibers, or plastic fibers to carry
