Concrete core testing is a vital method used to evaluate the in-situ strength and quality of hardened concrete by extracting cylindrical samples, or cores, from existing structures. These cores are subjected to compression tests to determine their compressive strength, which helps assess whether the concrete meets the specified design requirements. Additionally, core testing can reveal information about the concrete’s density, uniformity, and potential defects such as cracks or voids. This non-destructive or minimally destructive technique is essential for quality control, assessing structural integrity, and making informed decisions about the need for repairs or reinforcement in existing structures.
