Radiographic evaluation of concrete involves the use of radiographic test on building elements to examine the internal condition of concrete. This test is capable of examining concrete members without causing any damages.
protection and repair of reinforced concrete. There are 10 PARTS to the standard covering TEST METHODS for material properties and SPECIFICATION for the KEY REPAIR MATERIALS, including coatings, mortars, bonding agents and injection materials.
1 Απρ 2024 · Repair evaluation in civil structures by NDT is important although not widely applied so far. Elastic wave techniques exhibit sensitivity to damage and healing allowing evaluation of repair effectiveness. Modern tomography techniques enable visualization of repair in the volume of structures.
detection of distress and deterioration, enabling repair or rehabilitation before replacement is necessary. It is important that the inspector properly document any observations related to environmental and loading conditions. Inspections are often supplemented with nondestructive tests, destructive tests, and other investigations, especially
1 Αυγ 1998 · This paper presents the basic principles of various imaging techniques associated with several NDT methods applicable to concrete structures. The techniques considered are radiography, radioactive computerized tomography, infrared thermography, radar imaging and acoustic imaging.
The x-ray radiography by selective detection and the x-ray fan beam radiography systems at the University of Florida were used for testing and comparison in order to develop an efficient and a high-resolution x-ray backscatter imaging system.
The methodology for repairing a concrete structure typi-cally includes a condition assessment of the structure, designing repairs, developing construction documents, bidding and negotiation processes, and performing the repair work. Preparing a maintenance plan for the repaired structure is also recommended.
