Features of GPR (Ground Penetrating Radar)

Ground Penetrating Radar, or GPR, is a technique to study the patterns under the surface. In this method, radar pulses penetrate the interior and are struck on the surface. The material inside can reflect, refract, or scatter these pulses, basically microwaves in the electromagnetic band.


GPR does not involve destroying the surface and thus is part of NDT (Non-Destructive Testing). Therefore, it is deemed more efficient as it saves time, cost, and effort to bring the surface back to normality. 


We have mentioned below some features and applications of this technique. If you are interested in using or purchasing GPR equipment, you shall find these details helpful. Continue reading-
 

  • GPR is primarily used to study the presence and volume of concrete, pipes, masonry, metals, cables, etc., in the subsurface. 
  • The frequency range that a GPR tool emits lies between 10 MHz and 2.6GHz. 
  • The system comprises a transmitter, sending and receiving antennas, and a radar gram control unit. The receptor records the signals that one can study on a monitor.
  • GPR is used for military purposes to detect tunnels or metallic objects underground. 
  • The GPR technique is also applied in archaeology. The pulses can detect the presence of historical objects and their features. 
  • The most widely used application of GPR is in civil engineering. It can locate reinforcement bars or cables inside the concrete. The thickness of concrete is also measurable using this technique. 
  • Most GPR tools can penetrate up to 10m under the ground.
  • The scan rate of basic GPR tools is around 100 scans per minute.  

So we shared with you the details that will help you pick the right Ground Penetrating Radar.

Advantages of Universal Testing Machine

The main advantage of investing in a universal testing machine is that the device can be used to test the strength, durability, and suitability for most any material. A universal testing machine has the capability to pull, compress, bend, or stretch material to its breaking point. It is primarily used by laboratories that manufacture and or mould different types of plastics. A universal testing device features one or two vertical columns mounted on a base. A second horizontal plate contains attachments that are used to hold the sample and slides up and down during stress testing samples. Dual vertical column machines are preferred by most laboratories as they can handle larger samples in terms of size and weight. Determining tensile strength is the most common test performed in a universal testing machine. This is done by holding one end of a sample in place while the other is pulled away until two sides are torn apart. The same process is used for testing flexural str

Uses for Universal Testing Machine

Universal testing machine or UTM is aptly named as it can perform various types of tensile and compression tests on different materials. There are also many different terms used to refer to a UTM that you will commonly hear in the industry, among the most popular of which are a tensile tester, bend tester, and compression tester. Some types of UTMs are stripped of some capabilities and/or are marketed to specific sectors, like texture analyzers for food, peel tester for adhesives, labels, and tapes, and top load compression tester for pipes and packaging. True UTMs can perform all of these and more. They are great multi-purpose instruments for any QC or R&D laboratory. The following are only a few common uses for UTMs: Tensile testing – One of the most common applications for UTM, a tensile test measure how strong a material is, how long it can stretch, and how stiff it is as the material is pulled apart until breaking point. Compression testing – Compr

Importance of Ultrasonic Pulse Velocity Test in The Construction Industry

Image
In the construction industry, it is important to ensure that structures are built properly using the highest-quality materials and construction methods. Hence, certain tests must be conducted to ensure the quality of certain materials. The ultrasonic pulse velocity test is one of the most essential tests designed to determine the quality of natural rock and concrete. This testing method is preferred because it is non-destructive and it is conducted on site, saving builders a lot of time and money. In an ultrasonic pulse velocity test, the quality and strength of rock or concrete is determined by measuring the velocity of the ultrasonic pulse, which passes through the natural rock formation or concrete structure. The test is conducted using specialised equipment that generates a pulse of ultrasonic wave and measuring the time it takes for that pulse to go through the concrete. A high velocity indicates that the material is continuous and high-quality, and a slower velocity may
