Detection of crack in a concrete element by impact-echo method
Keywords:
Impact-echo method, concrete structure, crack detection.Abstract
Demonstrative experiment was done to verify ability of the impact-echo method to detect discontinuity, honeycombing or any defect in a concrete structure. Two beams of the length 7.5 m were investigated, the first one with an evident shear crack, the second one without visible deterioration. Observation confirmed assumptions and in the depth 2,0 m a discontinuity was detected.Downloads
