Assessing the compressive strength of concrete in an existing structure is essential when evaluating its ability to carry additional loads or after modifications. This is typically achieved through core sampling, which provides a representative measure of the concrete’s strength in different areas of the structure.

Testing Procedure

1. Core Sampling: Cores are taken from representative locations within the structure. This ensures the results reflect the overall strength of the concrete in different areas, accounting for potential variability.
2. Specimen Preparation: After being extracted, the concrete cores must be properly prepared for testing. This involves cleaning and possibly curing the cores to standard conditions before compressive strength testing.
3. Compression Testing: The prepared cores are subjected to compression testing using a suitable testing machine to measure their resistance to crushing under load. The results provide an indication of the concrete’s compressive strength, which is crucial for determining the structure’s capacity to bear additional or new loads.
4. Conformity Assessment: The results are then assessed for conformity against relevant standards or project specifications to ensure that the concrete meets the necessary strength requirements.
