METHOD OF ULTRASONIC TESTING OF CONCRETE STRENGTH Russian patent published in 2005 - IPC

Abstract RU 2262692 C1

FIELD: analyzing or investigating materials.

SUBSTANCE: method comprises measuring the time interval and velocity of ultrasonic propagation at least in ten section of the structure zone to be tested, calculating the mean and maximum velocity of ultrasonic, drilling and testing cores with subsequent determining of the strength in the sections that possesses mean and maximum velocity of ultrasonic, respectively, and calculating the strength from the formula proposed. The humidity of concrete is monitored during testing.

EFFECT: enhanced accuracy and reliability of testing.
