Dynamic Modulus of Elasticity:
It can be computed either through Resonant Frequency Test or Ultrasonic Pulse Velocity method.
Workability:
The following tests are commonly employed to measure workability:
- Slump Test
- Compaction Factor Test
- Kelly Ball apparatus
- Vee-Bee Consistometer
- Flow Test
Compressive Strength:
Non-destructive methods of testing concrete are Rebound Hammer Test, Dynamic or Vibration test, etc.
These tests are used for estimation of concrete strength and for comparative investigations.
Tensile Strength:
The test used to measure or estimate the tensile strength of the concrete is Cylinder Splitting Tension Test.
