concrete crushing test procedure

Concrete Block Crushing Machine Concrete Block Crushing. 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.Testing of Concrete
