Ultrasonic Testing of Concrete in Delhi, India

Advance inspection & Testing Lab is a Professionally managed Certified NDT testing lab in Delhi and providing Ultrasonic Pulse Velocity Testing Services in India. UPV test is done for quality control and inspection of concrete. Ultrasonic testing of concrete or ultrasonic pulse velocity test on concrete is a non-destructive test to assess the homogeneity and integrity of the concrete.

An ultrasonic pulse velocity (UPV) test is an in-situ, non-destructive test to check the quality of concrete. In this test, the strength and quality of concrete or rock are assessed by measuring the velocity of an ultrasonic pulse passing through a concrete structure.

Where Is Ultrasonic Pulse Velocity Test Useful?

Ultrasonic Testing

  1. Inspection of new and old structures, Concrete slabs, Concrete columns, Concrete walls, fire damaged areas, 
  2. Precast and prestressed beams, cylinders, and other concrete forms to identify honeycombs, voids, cracks, and other non-homogeneous conditions in concrete.

With This Ultrasonic Testing of Concrete, the Following Can Be Assessed

  1. Qualitative assessment of the strength of Ultrasonic testing of concrete, its gradation in different locat
    ions of structural members, and plotting the same.
  2. Any discontinuity in cross-section like cracks covers concrete delamination etc.
  3. Depth of surface cracks.

The Pulse Velocity in Concrete May Be Influenced By

  1. Path length
  2. The lateral dimension of the specimen tested
  3. Presence of reinforcement steel
  4. The moisture content of the concrete

Table 1 Shows the Guidelines for Qualitative Assessment of Concrete Based on UPV Test Results.

PULSE VELOCITY CONCRETE QUALITY
>4.0 km/s Very good to excellent
3.5 – 4.0 km/s Good to very good, slight porosity may exist
3.0 – 3.5 km/s Satisfactory but loss of integrity is suspected
<3.0 km/s Poor and los of integrity exist.
