Written by adminAugust 5, 2020 Introduction to Impact-Echo In this article, we will briefly review how to test concrete using impact-echo method. Impact Echo is an advanced non-destructive testing (NDT) method for evaluation of thin concrete and masonry members. Impact-Echo method works based on the use of stress waves. The test method
Written by adminJune 24, 2020 In this article, we will review an interesting category of ultrasonic test methods for concrete inspection and testing: Ultrasonic Pulse-Echo (UPE) is widely used for the inspection of concrete elements. The method has proven to be extremely useful in determining the thickness of concrete elements with one
Written by adminMay 29, 2020 In this article, and presentation, we are going to describe using non-destructive evaluation of cracking in concrete beams. The main reasons behind cracking is discussed. A systematic approach for evaluating the current condition of the beam is presented. Certain features of concrete cracks, such as the crack
Written by adminFebruary 10, 2020 Ground-Borne Vibration can be a serious concern for any building or structure within or adjacent to a construction zone. These structures may be potentially impacted by vibrations emanating from construction activities such as demolition, compaction, excavation, blasting, pile-driving, and operating heavy earth-moving equipment. In extreme cases, the
