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.

“No illusion is more crucial than the illusion that great success and huge money buy you immunity from the common ills of mankind, such as cars that won’t start.”
—Larry McMurtry (b. 1936)
“Mothers are likely to have more bad days on the job than most other professionals, considering the hours: round-the-clock, seven days a week, fifty-two weeks a year. . . . You go to work when you’re sick, maybe even clinically depressed, because motherhood is perhaps the only unpaid position where failure to show up can result in arrest.”
—Mary Kay Blakely (20th century)
“Without any extraordinary effort of genius, I have discovered that nature was the same three thousand years ago as at present; that men were but men then as well as now; that modes and customs vary often, but that human nature is always the same. And I can no more suppose, that men were better, braver, or wiser, fifteen hundred or three thousand years ago, than I can suppose that the animals or vegetables were better than they are now.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“The finest workers in stone are not copper or steel tools, but the gentle touches of air and water working at their leisure with a liberal allowance of time.”
—Henry David Thoreau (1817–1862)
“Reality is a question of perspective; the further you get from the past, the more concrete and plausible it seems—but as you approach the present, it inevitably seems incredible.”
—Salman Rushdie (b. 1948)
