Useful Applications of Ground Penetrating Radar

Ground penetrating radar (GPR) is state-of-the-art equipment used for exploring the subsurface of the earth. The cutting-edge imaging technology found in high-end GPR systems measures electromagnetic wave propagation and echo from the subsurface, which images and identifies changes in the magnetic and electrical properties beneath the surface of the earth. Hence, GPR systems are useful in locating underground utility lines in earth or post tensioning and reinforcing in concrete. Ground penetrating radar is surprisingly versatile for many other applications, including forensic research, land surveying, detecting unexploded land mines, conducting groundwater studies, and monitoring the structural integrity of airplane runways.



GPR is useful in many different fields. It is used to study ice, groundwater, soil, and bedrock under earth sciences and it may be helpful in finding diamonds and gold nuggets in alluvial gravel beds. In that case, ground penetrating radar is used to find natural traps in stream beds where heavy particles can accumulate. Space exploration has found some use for GPR, Yutu a Chinese lunar rover had a GPR on board to investigate the moon’s crust and soil.

Engineering applications for ground penetrating radar include locating buried utility lines and structures, non-destructive testing of pavements and structures, and identifying the characteristics of bedrock and soil. GPR is used in environmental remediation to determine the best sites for landfills and contaminant plumes. In archaeology, ground penetrating radar is helpful in mapping cemeteries, finding buried structures, and determining archaeological features. In law enforcement, GPR is valuable for finding buried evidence and locating unidentified or unmarked graves.

The military uses ground penetrating radar to find tunnels and mines. The reason why GPR is preferred for these applications is due to its speedy ability to acquire and produce data compared to other conventional geophysical methods. Hence, operators can easily and quickly produce measurements repeatedly, which can be crucial when determining rapid changes.

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 ...
