適用范圍：This European Standard describes a means of determining the tensile bond between sprayed concrete andsubstrate of concrete or rock tested in a laboratory as a direct tension test. Bond strength is defined as thecapacity to transfer tension between two layers. Bond strength is calculated as the ultimate tensile forcedivided by the stressed cross-sectional area of a core, drilled out of a sprayed concrete layer together with aportion of the substrate concrete or rock.Alternative in situ test methods for determining bond strength are allowed provided they meet all therequirements of this European Standard. In case of dispute, the method described in this European Standardis the reference test method.
