• Identify locations for core extraction

• Mark and prepare concrete surface

• Drill cores with diamond core drill

• Extract cores carefully without damage

• Measure dimensions and visually inspect for defects

• Cure cores if necessary for standard testing

• Conduct compressive strength tests using a compression machine

• Measure density and evaluate structural condition

• Compare results with original design specifications

• Prepare detailed technical report with recommendations

Concrete core testing is performed to evaluate in-situ strength and quality when standard cast specimens are not available or for existing structures. It provides a reliable measure of the actual performance of hardened concrete.

Cores are drilled, extracted, and tested in compression machines. Visual inspection and measurement ensure the quality and integrity of the samples. Testing allows evaluation of structural elements, detecting deterioration or inconsistencies.

The final report provides compressive strength results, density, and engineering recommendations for structural safety, rehabilitation, or modifications. Core testing is critical for assessing existing structures and verifying compliance with design standards.
