How to Test Concrete Using Impact-Echo ?
In this article, we will briefly present and discuss Impact-Echo (IE) method for testing concrete structures. The method has proven to be extremely useful in evaluating the thickness of concrete elements from one side (e.g. tunnel lining, culvert wall, bridge abutment), determining the depth and location of subsurface defects (e.g. cracks, voids, honeycombing, debonding) within concrete, and estimating the depth of surface-opening cracks. The test method was first adapted in… Read More »How to Test Concrete Using Impact-Echo ?
