NDT (NON DESTRUCTIVE TESTING) OF CONCRETE STRUCTURE ANSHULAnshul Shakya
Non-destructive testing (NDT) methods have a large potential to be part of such a system. NDT methods in general are widely used in several industry branches. Aircrafts, nuclear facilities, chemical plants, electronic devices and other safety critical installations are tested regularly with fast and reliable testing technologies. A variety of advanced NDT methods are available for metallic or composite materials. In reassessment of existing structures, have become available for concrete structures, but are still not established for regular inspections.
Therefore,the objective of this project is to study the applicability, performance, availability, complexity and restrictions of NDT. The purpose of establishing standard procedures for nondestructive testing (NDT) of concrete structures is to qualify and quantify the material properties of in-situ concrete without intrusively examining the material properties. There are many techniques that are currently being research for the NDT of materials today. It is focuses on the NDT methods relevant for the inspection and monitoring of concrete materials.

The quality of new concrete structures is dependent on many factors such as type of cement, type of aggregates, water cement ratio, curing, environmental conditions etc. Besides this, the control exercised during construction also contributes a lot to achieve the desired quality. The present system of checking slump and testing cubes, to assess the strength of concrete, in structure under construction, are not sufficient as the actual strength of the structure depend on many other factors such as proper compaction, effective curing also. Considering the above requirements, need of testing of hardened concrete in new structures as well as old structures, is there to assess the actual condition of structures.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

2. Non-destructive Testing
NDT is the process of inspecting, testing, or evaluating materials, components or
assemblies for discontinuities, or differences in characteristics without destroying the
serviceability of the part or system. In other words, when the inspection or test is
completed the part can still be used
.
3. Why and When NDT Used
Test piece too precious to be destroyed
Test piece to be reuse after inspection
Test piece is in service
For quality control purpose
Flaw Detection and Evaluation
Leak Detection
Location Determination

Structure and Microstructure Characterization
4. Major types of NDT
Detection of surface flaws
Visual
Magnetic Particle Inspection
Fluorescent Dye Penetrant Inspection
Detection of internal flaws
X-Radiography
Ultrasonic Testing
Eddy current Testing
5. Visual
Most basic and common inspection method.
Tools include fiberscopes, bore scopes, magnifying glasses and mirrors.
Portable video inspection unit with zoom allows inspection of large tanks and
vessels, railroad tank cars, sewer lines.
Robotic crawlers permit observation in hazardous or tight areas, such as air ducts,
reactors, pipelines.
6. Magnetic Particle Inspection (MPI)
A nondestructive testing method used for defect detection. Fast and relatively easy to apply and
part surface preparation is not as critical as for some other NDT methods. – MPI one of the most
widely utilized nondestructive testing methods.
MPI uses magnetic fields and small magnetic particles, such as iron filings to detect flaws in
components. The only requirement from an inspect ability standpoint is that the component
being inspected must be made of a ferromagnetic material such as iron, nickel, cobalt, or some
of their alloys. Ferromagnetic materials are materials that can be magnetized to a level that will
allow the inspection to be affective.
The method is used to inspect a variety of product forms such as castings, forgings, and
weldment. Many different industries use magnetic particle inspection for determining a
component's fitness-for-use. Some examples of industries that use magnetic particle inspection
are the structural steel, automotive, petrochemical, power generation, and aerospace
industries. Underwater inspection is another area where magnetic particle inspection may be
used to test such things as offshore structures and underwater pipelines.
7. Magnetic particle inspection Method
Magnetic flux lines in a ferromagnetic material (resulting from the application of a
magnetic field) are distorted around a defect.
Distortion causes magnetic flux lines to protrude from the surface at the location of the
surface crack. This is known as “field leakage”.
Field leakage attracts magnetic particles (Fe or Fe3O4) that are applied to the surface.
Subsurface cracks near the surface can also be detected.
Applied magnetic field is preferably perpendicular to the length of the defect.
8. Distortion of the magnetic flux lines due to a surface crack in a magnetic material
Distortion of the magnetic flux lines due to a subsurface defect
Little distortion of the magnetic flux lines when the length of the defect is parallel to the
applied magnetic field
9. Magnetic Particle Inspection
Pulverized iron oxide (Fe3O4) or carbonyl iron powder can be used
Colored or even fluorescent magnetic powder can be used to increase visibility
Powder can either be used dry or suspended in liquid
MPI is used for direct, visible indication on surface.
10. Indication of a crack in a saw blade Indication of cracks in a weldment
Before and after inspection pictures of cracks
emanating from a hole
Indication of cracks running between attachment holes in a
hinge
Examples of visible magnetic particle indications
11. Dye Penetrant Inspection
Liquid penetration inspection is a method that is used to reveal surface breaking flaws by bleed out
of a colored or fluorescent dye from the flaw.
The technique is based on the ability of a liquid to be drawn into a "clean" surface breaking flaw by
capillary action.
Liquid penetrant inspection (LPI) is one of the most widely used nondestructive evaluation (NDE)
methods. Its popularity can be attributed to two main factors, which are its relative ease of use and
its flexibility. LPI can be used to inspect almost any material provided that its surface is not extremely
rough or porous. Materials that are commonly inspected using LPI include metals (aluminum,
copper, steel, titanium, etc.), glass, many ceramic materials, rubber, and plastics.
12. Process
1. Surface Preparation: One of the most critical steps of a liquid penetrant inspection is the surface
preparation. The surface must be free of oil, grease, water, or other contaminants that may
prevent penetrant from entering flaws. The sample may also require etching if mechanical
operations such as machining, sanding, or grit blasting have been performed. These and other
mechanical operations can smear the surface of the sample, thus closing the defects.
2. Penetrant Application: Once the surface has been thoroughly cleaned and dried, the penetrant
material is applied by spraying, brushing, or immersing the parts in a penetrant bath.
3. Penetrant Dwell: The penetrant is left on the surface for a sufficient time to allow as much
penetrant as possible to be drawn from or to seep into a defect. The times vary depending on
the application, penetrant materials used, the material, the form of the material being
inspected, and the type of defect being inspected. Generally, there is no harm in using a longer
penetrant dwell time as long as the penetrant is not allowed to dry.
4. Excess Penetrant Removal: This is the most delicate part of the inspection procedure because
the excess penetrant must be removed from the surface of the sample while removing as little
penetrant as possible from defects. Depending on the penetrant system used, this step may
involve cleaning with a solvent, direct rinsing with water, or first treated with an emulsifier and
then rinsing with water.
13. 5. Developer Application: A thin layer of developer is then applied to the sample to draw penetrant trapped in flaws
back to the surface where it will be visible. Developers come in a variety of forms that may be applied by dusting (dry
powdered), dipping, or spraying (wet developers).
6. Indication Development: The developer is allowed to stand on the part surface for a period of time sufficient to
permit the extraction of the trapped penetrant out of any surface flaws. This development time is usually a minimum
of 10 minutes and significantly longer times may be necessary for tight cracks.
7. Inspection: Inspection is then performed under appropriate lighting to detect indications from any flaws which may
be present.
8. Clean Surface: The final step in the process is to thoroughly clean the part surface to remove the developer from the
parts that were found to be acceptable.
15. X-radiography
Radiography involves the use of
penetrating gamma- or X-radiation to
examine material's and product's
defects and internal features.
An X-ray machine or radioactive
isotope is used as a source of radiation.
Radiation is directed through a part and
onto film or other media.
The resulting shadowgraph shows the
internal features and soundness of the
part.
Material thickness and density changes
are indicated as lighter or darker areas
on the film.
The darker areas in the radiograph
below represent internal voids in the
component.

16. Method: Send x-rays through the material
and detect the transmitted x-ray image using
a photographic film
Method
17. Ultrasonic Testing
In ultrasonic testing, high-frequency sound waves are transmitted into a material to
detect imperfections or to locate changes in material properties.
The most commonly used ultrasonic testing technique is pulse echo, whereby sound
is introduced into a test object and reflections (echoes) from internal imperfections or
the part's geometrical surfaces are returned to a receiver. The time interval between
the transmission and reception of pulses give clues to the internal structure of the
material.
18. Ultrasonic Inspection
High frequency sound waves are
introduced into a material and
they are reflected back from
surfaces or flaws.
Reflected sound energy is
displayed versus time, and
inspector can visualize a cross
section of the specimen showing
the depth of features that reflect
sound.
19. Generation of Ultrasonic Waves
The active element or Piezoelectric transducers is the heart of the transducer as it
converts the electrical energy to acoustic energy, and vice versa.
Piezoelectric transducers are used for converting electrical pulses to mechanical vibrations
and vice versa
Commonly used piezoelectric materials are quartz, Li2SO4, and polarized ceramics such as
BaTiO3 and PbZrO3.
Usually the transducers generate ultrasonic waves with frequencies in the range 2.25 to
5.0 MHz
20. Eddy Current Testing
Eddy currents are loops of electric current induced within conductors by a changing magnetic field in
the conductor, due to Faraday's law of induction. Eddy currents flow in closed loops within conductors,
in planes perpendicular to the magnetic field.
Electrical currents are generated in a conductive material by an induced alternating magnetic field. The
electrical currents are called eddy currents because the flow in circles at and just below the surface of
the material. Interruptions in the flow of eddy currents, caused by imperfections, dimensional changes,
or changes in the material's conductive and permeability properties, can be detected with the proper
equipment.
Eddy current testing can be used on all electrically conducting materials with a reasonably smooth
surface.
The test equipment consists of a generator (AC power supply), a test coil and recording equipment, e.g.
a galvanometer or an oscilloscope
Used for crack detection, material thickness measurement (corrosion detection), sorting materials,
coating thickness measurement, metal detection, etc.
22. Principle of Eddy Current Testing
When a AC passes through a test coil, a primary magnetic field is set up around the coil
The AC primary field induces eddy current in the test object held below the test coil
A secondary magnetic field arises due to the eddy current
23. Advantages & Limitations
Can be applied to welds, tubing, brazing, castings,
billets, forgings, aluminum parts, turbine blades and
disks, gears.
Specimen Can re used.
Used for metals, nonmetals and composites.
Used on dense or thick material.
Used on all shapes and forms; castings, welds,
electronic assemblies, aerospace, marine and
automotive components
Need access to test surface defects must be surface breaking
decontamination & pre cleaning of test surface may be
needed
