Non-Destructive Testing Equipment for Concrete

Non-Destructive Testing Equipment for Concrete

Testing equipment is used to ensure the quality and the life of a product. These test tools are classified into the destructive types and the non-destructive types. The non-destructive test equipment is largely used in sectors where specimen checking is impossible and in cases where if the product is damaged the consequences are irrecoverable.

Concrete is one common area where the non-destructive testing tools are largely used. These tools can be highly useful as concrete is one of the places where tools that damage the product cannot be used to ensure its quality. So non-destructive tools are used in the process of testing the quality. However, in the process of testing, the structure and the type of concrete should be known in order to carry out the testing process perfectly. Listed below are some of the common tools that are a part of the non-destructive testing equipment.

Non-Destructive Testing Equipment for Concrete

Concrete Strength testers:

The first tool on the list is, in fact, the most important one as well. This non-destructive tool helps in finding out the strength of the concrete, and it can be done at varying degrees with the help of advanced tools that are available in an extensive range.

Ultrasonic concrete tester:

Ultrasonic devices are also a part of the non-destructive test equipment. These instruments either generate stress waves or sound waves that are used to determine the quality of the other materials that are used as a part of the concrete with destroying the basic structure.

Corrosion Testers:

Two things have to be kept in mind as far as concrete basements or flooring is concerned. Concrete has steel bars within them, and not all concretes are corrosion resistant. So as these corrosion testers ensure both the quality of the steel bars within concrete and also the corrosion resistance of the concrete.

Rebar Locators:

Rebar locators are exclusively used to measure the quality of the reinforcing bars present within the concrete. Once the construction begins to take shape, it might be difficult to ascertain the quality of the steel bar within. Rebar locators make the job easy and testify the quality of the steel bars inside the concrete.

Moisture and Flow testers:

A lot of construction materials are involved in the process of concrete. The quality and the moisture content of every single component involved will play a role in the standard of the concrete. So these moisture testers ensure the quality of the materials used as a part of the concrete thereby determining the final quality of the building.

Ultrasonic Pulse velocity meter:

Just like the concrete testing tool that was used in the beginning process, pulse velocity meter is used after the construction of the building is wound up. This instrument also employs ultrasonic waves to test the quality, uniformity, porosity and the placement of the concrete in the building. This will ensure the safety and the life of the building.

 

How Does Thermal Analysis Work?

Thermal Analysis

To know how thermal analysis works it is important that we understand what thermal analysis is and where it is used. Thermal Analysis influences that part of science that deals with materials. There are almost 11 known types of thermal analysis. Depending on the situation and the material that is about to undergo the test these thermal analyses are classified. In the process of thermal analysis, the administer makes an effort to find how a material reacts at different temperatures. In simple terms change in material in correspondence with the change in temperature. This is the simple science behind the thermal analysis.

Thermal Analysis

History and Scope of Thermal Analysis:

  • It is quite interesting to note that thermal analysis came into existence during the BC days. This is because most of the changes that natural sciences dealt with were with regard to fire. So they regarded fire as the basic matter that propelled change within two physical quantities.
  • Keeping the above point in mind, the sciences that followed also employed fire as the considered it as the general analyzer of matter. However, they kept redefining the word fire with words like heat and temperature.
  • Thermal Analysis is primarily used in the pharmaceutical industry. So it has to be either a chemist or a pharmacist who will possibly be handling the thermal analysis procedures.
  • Usage of thermal analysis is widely used in the chemical industry. This is because the change in the reaction between two materials can be monitored quickly be a chemist only with the fluctuation in temperature.
  • Almost all the studies carried out in the purview of thermal analysis can be classified into three major heads. They are Mass, Temperature or other parameters such as dimensions, etc. Depending what head the materials fall into, the method of thermal analysis is chosen.
  • There is also a concept called Simultaneous Thermal Analysis where the method enables the application of two processes such as a thermal analysis and a differential scanning calorimetry on the same material, at the same time and also in the same instrument.
  • The common application of thermal analysis is found in pharmaceutical materials, polymer, metal, food and printed circuit boards

Now that you have gotten a basic idea of what is thermal analysis, let us see how the process works:

Process of thermal analysis:

  • Thermal Analysis begins with finding the right method that has to be applied to the material that is undergoing the test.
  • Once the suitable method is found, the next thing is to apply the same onto the materials. A set of tools and instruments are required to carry out the process. Once you have the things set, you can get to the process of thermal analysis.
  • At varying degrees of heat, the material is tested, and the corresponding changes are recorded along with the results. The point at which the material is found to give the required result is what we find through the thermal analysis.

 

All that you have to Know about Radiography

Radiography

Radiography is a technique that used the electromagnetic radiation to view the internal structure of an object. This is what happens with radiography. Radiography comes along with an X-ray generator. These X-rays are responsible for creating the electromagnetic radiation that pierces the body and scans whatever is inside. The images that are generated in radiography are all two-dimensional images. They are not elevated or superimposed. This is where the role of CT scanning technique enters. CT which expands as Computed tomography, brings in a set of these two-dimensional images processes it and then turns it into a three-dimensional image.

Now having spoken about the basic things about radiography, here is one confusion that prevails in the heads of most of the people. The confusion is as to, what is the difference between a radiologist and a radiographer. So let’s find out the difference between a radiographer and a radiologist.

Radiography

Radiographer:

A radiographer is a person who has knowledge of accessing the instruments along with radiography. They take care of patients and assist them in treatments that are associated with radiography. This is the job of a radiographer. Radiographers are doctors. They are simply medical technicians who are involved in the process of radiography. Radiographers play a role in different medical teams as in CT scan, Radiotherapy treatment, patient care, X-ray, and MRI. They can assist in the process of radiography and can carry out the whole, but they cannot interpret the results and suggest medication.

Radiologist:

In contrary to the above, a radiologist is a doctor who has specialized skills in the field of radiography. A radiologist knows when and where radiography has to take place and the patient who is required to go through such treatment, while a radiographer can only tell you how to do it. Once the process of radiography is done, the radiologist can look at the result and interpret the status of the patient and suggest medication. This is the role of the radiologist in the process of radiography. Without the radiologist, the process would stay incomplete.

Now we clearly know the difference between a radiographer and a radiologist. So it is pretty much vivid that both the professional are imperative for radiography. While one is sound with the machine and other is sound in the medical perspective making their roles significant.

In the recent times, the scope for both the radiographer and the radiologist has largely increased. There are certain degrees that a person has to complete in order to qualify himself as a radiographer. A lot of institutes today cater these courses that help a lot of upcoming aspirants in this profession.

 

Role of Ultrasonic Devices in Industry

Ultrasonic Devices

Ultrasonic waves are those waves that have a range that is more than the upper limit of the audibility range of a normal human being. Which means the sound that is generated by the ultrasonic waves is not audible for the human ears. The word ‘ultrasonic’ is more often associated with hardware and engineering industry. But in reality, they play a significant role in the medical field as well.

Ultrasonic Devices

Ultrasonic in industries:

  • As far as the usage of the ultrasonic waves in the industrial sector is concerned, it plays a major role in the testing sector. It is one of the most common methods used in the non-destructive testing equipment.
  • In case if you didn’t know about these testing methods, testing the quality of a product can be classified into destructive testing methods and non-destructive testing methods. Since we are restricting ourselves to the non-destructive testing methods, we will see what this non-destructive method is. In the process of assuring the quality of a product the manufacturers employ testing methods, and if these testing methods come out with results with affecting the product or damaging them, then they are known are non-destructive testing methods. So non-destructive testing has to do with Ultrasonic waves? Ultrasonic waves are also utilized by the industries to test the quality of the product and this testing falls under the non-destructive category.
  • They analyze the product and give out the results without tampering the product. That is the reason why ultrasonic waves are associated with the non-destructive testing equipment. Most of the tools and equipment that are designed for the non-destructive testing purpose have the influence ultrasonic waves in them.
  • This ultrasonic method is employed in areas where the inspection is critical, making it an important part of the industries.
  • In industries that involve a lot of complex engineering as in the case of an aircraft, if damaged can be easily spotted and rectified with the help of ultrasonic waves. Prospectively dangerous situations can also be avoided as these methods in most cases are non-destructive and do not explore or exploit the other associated parts unless directed to do so. This makes rectification much easier than before. So this means, ultrasonic waves do not just stop with ensuring quality but also assists in rectifying the errors if any spotted.
  • Apart from non-destructive testing, ultrasonic waves are used in drilling, welding, soldering, cutting and machinery, cleaning and sonar. So the usage of ultrasonic waves is pretty much versatile than we can imagine.

Process:

The process in which these waves work is simple. The medium that uses the waves s what that matters. It is simply the transmission of rays, and the rays reflect through the medium that they are sent through. They precisely act on the spot where checking or rectification is required, without damaging the system and the transmission gets back to the source from where it was earlier generated. This is the process involved in the industrial ultrasonic transmission.

Uses of Non-Destructive Test Equipment

Non-Destructive Test Equipment

The production stage of almost all manufacturing processes will go through a lot of inspection and quality control stages. This is done to ensure that the product comes out in proper quality and makes sure the product lives its life. This is the reason behind employing test equipment in engineering. These test tools that are used in the process of testing are categorized into Destructive and Non-Destructive. So we get to see the uses of non-destructive test equipment, let us first understand what are non-destructive test tools and how they differ from the destructive ones.

Non-Destructive Test Equipment

Non-destructive test equipment:

Non-destructive test tools are some specific variety of techniques that are used both in science and in the industry to analyze and understand the properties of a product or a system without damaging the product. So the definition of non-destructive test tool is what the name self-explains.

Having explained this, we should forget the concept of ‘Destructive test equipment’. So, the first doubt that comes to our mind is that ‘Do test tools damage a product or a component in the process of testing?’ Yes, they do. This is where the concept of specimen test appears. All products are manufactured, and one among them is chosen as a specimen, and the testing analysis is carried out on that product. Since all the products are manufactured and produced in the same concept, the quality of the specimen acts as a testimony to the other similar products. Now that we know the terms let’s see the uses of non-destructive test equipment.

Uses of non-destructive test equipment:

The below listed are some of the non-destructive test tools and their uses.

Break-off tester:

Break-off tester is largely used in the construction sector. It is used both as a part of curing and in laying the concrete. Break-off tester is used to measure the strength of the concrete and the control in the curing process. This is important as the strength of the building depends on the strength of the concrete.

Capo test:

Again this has something to do with concrete. However, the application is quite different. Here capo test is done when the structure and the type of concrete are unknown at the time of testing. In such instances to avoid the inconveniences in ensuring the quality, Capo test is done.

Crack Measuring Microscope:

There are chances of concrete floors and basements having cracks that can affect the quality of the building. This instrument measures the width of the crack that is present in the concrete accurately. This enables people to take appropriate measures at the earliest.

Borescope:

A borescope is an equipment enabled with cold light supply and camera. In case, if there are cracks in hidden spaces and narrow path where it is usually hard to locate, borescope with its camera and other accessories finds and measures the crack with ease.
