• Collect fresh concrete samples from casting location

• Cast cubes or cylindrical specimens according to standard dimensions

• Cure samples under controlled temperature and humidity conditions

• Measure dimensions and mass before testing

• Place specimen in compression testing machine

• Apply load gradually until failure

• Record maximum load and calculate compressive strength

• Repeat tests for multiple specimens for reliability

• Compare results with design strength requirements

• Prepare detailed report with findings

Concrete compressive strength testing ensures that the material meets design requirements for structural performance. In Sri Lanka, where environmental conditions can impact curing, this testing is critical for quality assurance.

Cubes or cylinders are cast from fresh concrete and cured under controlled conditions. They are then tested in compression machines, and the maximum load at failure is recorded to determine concrete strength.

The report includes compressive strength results, comparison with design specifications, and recommendations. This testing is essential for verifying material quality, structural safety, and regulatory compliance.
