That's the whole point of the construction project dropping the extra cash – when water seeps in the tiny fractures in concrete, they don't want the rebar to swell and expand with rust and split the concrete wide open. It's called oxide jacking, and it makes bridge owners cranky. Stainless won't do that.Concrete Testing Equipment, Non-Destructive TestingFlexural tests on concrete are performed two ways. Center-point load tests (ASTM C293) concentrates stress at the sample's center point, while three-point load tests (ASTM C78) apply force uniformly to the middle one-third of the specimen. Center-point load tests typically show results 10 to 15 percent higher than three-point test results.
