VILAS NIKAM-NONDESTRUCTIVE TESTING

  1. 1. APOWERPOINT PRESENTATION ONNON-DESTRUCTIVE TESTING PREPARED BY MR.NIKAM VILAS NAVNATH LECTURER(M.I.T.DHANORE) E-mail:-vilas5151@gmail.com
  2. 2. INTRODUCTION• DEFINATION: Testing of concrete without destructing or disturbing or damaging or breaking actual structure of concrete member.
  3. 3. ADVANTAGES OF NDT1) Wastage of material is avoided.2) Strength of member can be checked at any time , at any point.3) Less time is required.4) Strength of wetted as well as dried sample can be tested.
  4. 4. METHODS OF NDT• Rebound Hammer Test.• Pulse velocity Test.• Surface Hardness Test.• Penetration & Pull out Technique.• Dynamic or Vibration Test.• Radioactive & Nuclear Method.• Magnetic & Electrical Method.• Acoustic & Emission Technique.
  5. 5. A) Schmidt’s Rebound Hammer Test.
  6. 6. Principle’s Rebound Hammer Test.
  7. 7. Actual Testing
  8. 8. How to Take Reading ?
  9. 9. But what is the Problem?
  10. 10. B) Pulse velocity Test.• Principle:- Measurement of time of pulse to travel through a concrete member.
  11. 11. Working of Pulse velocity Test
  12. 12. Actual model
  13. 13. How to Take Reading ?
  14. 14. Conclusion• Time Saving Technique.• Economy is achieved.• Comfortable.• Flexibility in state of material.
  15. 15. References• Concrete technology by M.S SHETTY.• Concrete technology by M.L. GAMBHIR.
