Non-Destructive Testing Method of Concrete Using Impact Acoustics

Non-destructive Impulse Response S’mash Method for Concrete Pile Testing

Nowadays, in the civil engineering practice, the pile-building is the most universal type of foundation. It is usually associated with bridges, fly-overs and other civil engineering objects, industrial buildings, tall buildings, chimneys, tanks etc [1]. It is essential to control the quality of concrete piles. The most accepted weight-bearing capacity measurement technique is the static probe l...

Artificial neural networks for non destructive testing of concrete structures

In this paper, the determination of defects in concrete structures using an ultrasound technique is discussed. A diagnostic model for concrete pillars by means of Multi Layer Perceptron neural networks is developed to locate and classify the defects. Finite Elements numerical techniques have been used to model a concrete pillar of specified size (i.e., rectangular cross section and 2 meters in ...

Non-Linear Non-Destructive Evaluation of Concrete

This paper explains non-linear non-destructive evaluation of concrete aimed at examining the occurrence of non-linearity under non-linear wave propagation through the concrete. Standard cubic concrete sections in damaged and undamaged conditions were investigated. The specimen was first damaged under compression testing and then subjected to non-linear ultrasonic evaluation in two directions i....

Improving Non-Destructive Concrete Strength Tests Using Support Vector Machines

Non-destructive testing (NDT) methods are important alternatives when destructive tests are not feasible to examine the in situ concrete properties without damaging the structure. The rebound hammer test and the ultrasonic pulse velocity test are two popular NDT methods to examine the properties of concrete. The rebound of the hammer depends on the hardness of the test specimen and ultrasonic p...
