APPARATUS AND METHOD FOR MEASURING ADHERING FORCE OF CONCRETE USING UNIAXIAL TENSILE TEST

摘要

PURPOSE: An apparatus and a method for measuring adhering force of concrete are provided to improve precision of measuring result by minimizing parameters caused by an eccentricity of a test member. CONSTITUTION: An adhering force measuring apparatus for concrete includes an old concrete sample having a column shape. The old concrete sample has predetermined diameter and height. A new concrete sample is positioned adjacent to the old concrete sample. First and second nipple pipes(200,300) cover the old concrete sample and the new concrete sample. An adhesive member(250) is applied in a contact portion between the old concrete sample and the first nipple pipe(200) so as to integrally form the old concrete sample with the first nipple pipe(200). A tensile device is provided to provide tensile force with respect to the first and second nipple pipes(200,300). The tensile device is coupled to the first and second nipple pipes(200,300) by means of a connecting member(400).
