Testing the Compressive Strength of Concrete — What, why

A 3 or 7-day test may help detect potential problems with concrete quality or testing procedures at the lab but is not a basis for rejecting concrete, with a requirement for 28-day or other age strength. ASTM C 1077 requires that laboratory technicians involved in testing concrete must be certified.

Concrete Testing Equipment | ELE International

Concrete cores can be taken from hardened concrete for testing, but Non-destructive Test (NDT) equipment enables the testing of in-situ concrete or concrete samples. ELE provides crack detection microscopes, and a (Schmidt) rebound hammer, or test hammer, for measuring surface hardness and penetration resistance.

How to Attach New Concrete to Old Concrete With Pins | Hunker

When joining new concrete work to old concrete work, the joint will always develop a crack and will be a point of expansion and contraction. Over time this expansion and contraction, especially if they occur at different rates due to the sections of concrete being exposed to different temperatures, will work the sections apart, and the crack will widen.
