WebIt is especially suitable for testing large-diameter piles, secant pile walls, and slurry-wall elements. If a defect is found, the steel tubes may be pierced at the corresponding depth and the pile repaired by grouting. The piles can be tested after the concrete has gained some strength, usually at an age of five days or more from casting. WebUltrasonic testing is a classical non-destructive testing method, which is finding more and more applications in civil engineering. For ultrasonic testing of concrete a fre-quency range of 50 to 200 kHz is typically used. This range is controlled by the concrete properties such as aggregate size and pore distribution which affect the ...
