NDT (Non destructive testing)

Non Destructive Testing is a useful tool to evaluate the condition of a structure without damaging it. These tests for concrete and metal structures are employed to assess their physical and mechanical properties and detect any imperfections like cracks, voids etc.

Purpose of Non Destructive Testing

  • Estimating on site compressive strength
  • Deleting the presence of cracks, voids and other imperfections.
  • Monitoring structural changes in concrete overtime.
  • Assessing uniformity and homogeneity
  • Assessing the condition of prestressing /reinforcement steel especially regarding corrosion.

Methods of Non Destructive Testing

  • Penetration method
  • Rebound hammer test
  • Pull out test method
  • Ultrasonic pulse velocity method
  • Carbonation Test
  • CAPO Test
  • Half Cell Potential
  • Load Test
