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

Features & Applications of Piezometer in Construction

Image
In geotechnical and civil engineering different tools are required and utilised to ensure a high-quality construction. The piezometer is one of the devices that is helpful in measuring pore water pressure. Some of the most advanced piezometers come with a vibrating wire, making them more effective in the method of converting fluid pressure into a frequency signal on a sensitive diaphragm. Frequency signals can be used in demanding environments, making them ideal in applications involving civil engineering. The signals are capable of being transmitted in long distances without degrading. Moreover, they are resistant to electrical external noise and they can tolerate wet wiring conditions. A vibrating wire gauge works based on the principle that when a tension wire is plucked, it vibrates at a resonant frequency. A magnetic coil surrounds the wire, and when plucked by a data logger interface, the result is the vibration’s resonant frequency. Changes in the distance between the

All That You Need to Know About Universal Testing Machine

Image
Universal testing machines are used to measure the force being applied to various materials and the deformation that occurs as a result. They are commonly used for testing the strength of steel reinforcing bars while under tension. They can be used to conduct tests to determine a material’s shear, flex or bend, peel, tear, puncture or burst, friction, torsion, friction, heat distortion temperature, and stiffness, too. Some of the most common types of universal testing machines are hydraulic and electromechanical testing equipment, which are designed, developed, and manufactured to conform to various standards. Some machines can be more versatile with the addition of certain types of accessories, like load cells, fixtures, grips, and platens. ‘Universal’ pertains to the many different types of standard compression and standard tests on structure, components, and materials. A basic universal testing machine will have the components including the load frame that typically consist

A Look into Soil Testing Equipment

Image
Soil is the base of foundations for any construction project. It acts as a support for roads and other crucial infrastructure. It makes good sense to ensure that you are building on an appropriate soil before construction begins. Soil testing provides information that can help construction companies and engineering firms determine the mechanical behaviour of soils. Testing can be conducted using the right equipment and accessories that go with them. High-quality soil testing equipment can characterise the soil samples on site or in the laboratory. Some equipment lets you collect soil samples, classify soils, and evaluate the mechanical property of the material. Here are some of the different types of soil testing equipment : CBR test machines – California Bearing Ratio is the test for measuring subgrade soil and highway sub base and subgrade strength. The process involves a penetration test, and the machines are ideal for testing cohesive materials, which are
