CORE SAMPLING AND TEST FOR DAMAGE ASSESSMENT

Abstract

Core sampling and test or core extraction test is the examination and compressive strength testing of cores drilled from hardened concrete enable the visual inspection of interior regions of the structural member along with estimation of actual concrete strength. A more direct assessment on strength can be made by core sampling and testing.

In addition to assessment of strength, core test is evaluating structural capacity or safety assessment. The process involves extracting cylindrical samples (cores) from existing concrete structures to determine various properties and potential degradation. These cores are then subjected to a series of tests to measure characteristics such as compressive strength, density, and moisture content. The results provide valuable insights for maintenance and repair.

Core test is a semi-destructive test of concrete.  If the core test result deviate significantly from the expected design strength, it can indicate potential issues with the concrete mixture, placement and curing process. This allows for appropriate remedial action to be taken if necessary. This helps ensure the structure meets the design specification and safety requirements.
