Jan 09 20200183322 The PullOut Test The concept behind PullOut Test is that the tensile force required to pull a metal disk together with a layer of concrete from the surface to which it is attached is related to the compressive strength of the concreteThe pull out test is normally used for early diagnosis of strength problems However it can be used to evaluate the strength of concrete in existing
