Abstract

A new method called the adhesive-bonded anchorage pullout test is proposed in the paper to estimate the in-place concrete compressive strength. In this method, a threaded metal insert is anchored into the concrete by means of a high strength adhesive. To estimate the concrete compressive strength, the pullout force when the anchorage system fails is measured. The embedded depth and the diameter of the reaction ring are determined by theoretical and experimental analysis. The empirical correlation relationships between the pullout forces of this new method and the compressive strengths of concrete cubes are presented for concrete specimens with varying concrete mixes in the 10–80 MPa strength range. In order to assess the accuracy of this method on site, verification tests are undertaken on a number of concrete structures. The experimental and analytical studies show that the newly proposed method is accurate in estimating the in-place concrete compressive strength.
