Common Failure Modes of Steel Reinforced Concrete
Reinforced concrete can fail due to inadequate strength, leading to mechanical failure, or due to a reduction in its durability. Corrosion and freeze/thaw cycles may damage poorly designed or constructed reinforced concrete. When rebar corrodes, the oxidation products (rust) expand and tends to flake, cracking the concrete and unbonding the rebar from the concrete. Typical mechanisms leading to durability problems are discussed below.

“For all Men would be Cowards if they durst:
And Honesty’s against all common sense—”
—John Wilmot, 2d Earl Of Rochester (1647–1680)
“... until both employers’ and workers’ groups assume responsibility for chastising their own recalcitrant children, they can vainly bay the moon about “ignorant” and “unfair” public criticism.

“For when they meet, the tensile air
Like fine steel strains under the weight
Of messages that both hearts bear—
Pure passion once, now purest hate....”

“freeways fifty lanes wide
on a concrete continent
spaced with bland billboards
illustrating imbecile illusions of happiness”
