Factors Affecting Rebound Value

Factors Affecting Pulse Velocity

• Degree of coupling
• Presense of reinforcement
• Concrete temperature
• Moisture content
• Mix proportion
• Age of Concrete
• Stress level in Concrete
• Concrete strength can be predicted within 20% provided calibration curve is established

Applications Of Pulse Velocity Method

• Main application for assessment of concrete uniformity.
• To establish areas of deteriorated concrete.
• Detection of cracks .
• Calculation of dynamic young’s modulus.
