Testing sprayed concrete - Part 4: Bond strength of cores by direct tension
Also Known As:
The DIN EN 14488-4 standard provides guidelines for testing the bond strength of cores in sprayed concrete using direct tension. The purpose of this test is to determine the ability of the sprayed concrete to bond with the underlying substrate, which can be either concrete or rock.
The bond strength is calculated by measuring the ultimate tensile force applied to the core and dividing it by the stressed cross-sectional area. The core is obtained by drilling it out from the sprayed concrete layer along with a portion of the substrate.
The standard also includes amendments to the EN 14488-4:2005, which specify requirements for using alternative test methods and partially drilled specimens. These amendments ensure that accurate and reliable results are obtained when conducting the bond strength test.
