Predict The Behaviour of Soil with Soil Testing Equipment

The soil often serves as the base of foundations of structures, support for roads, and other crucial infrastructure. For this reason, soil testing is one of the mandatory tests construction companies, and engineering firms conduct to predict the mechanical behaviour of soils. With the proper soil testing equipment, it is easier to determine the behaviour and quality of the soil before you begin building on it. The equipment is designed to be accurate in characterising soil samples on-site or in the laboratory. High-end systems come with tools for collecting samples, classifying soils, conducting mechanical property evaluation, and testing the completed sub base or road base on site.

The triaxial shear test system is among the commonly used soil testing equipment. It measures the mechanical properties of soils and other deformable solids, like clay, sand, and granular materials. In this test, the effects of certain applications like excavations, tunnelling, and building constructions on soil can be simulated successfully. A triaxial test determines the relationship between stress and strain in undisturbed soil specimens by subjecting the sample to different drainage conditions and stress levels. The most advanced triaxial test systems automatically conduct compression tests on remoulded and cylindrical undisturbed soil samples.

Another way to predict the behaviour of soil is by the California Bearing Ratio (CBR) test. CBR testing machines measure the strength of the highway sub base and subgrade and subgrade soil with a penetration test. It is aimed at testing cohesive materials of a particular size, usually less than 19mm. There are different types of CBR test machines and are often classified as field testing systems or laboratory equipment.

Soil consolidation is determined by an odometer. High-quality front loading odometers have a solid build and designed to let you load the sample through the lever arm assembly and any of the three alternative beam ratios (9:1, 11:1, and 10:1). The beam comes with a beam support jack and counter balance weight, and the cell platform is designed to work with a full range of consolidation cells, with a central spigot to make sure that the cell is accurately centred under the loading.

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

Precautions to Be Taken While Using a Piezometer

The piezometer is a measuring device that determines pore pressures underground and liquid pressure. By determining pore pressure, you can understand the behaviour of the ground before, during, and after a construction project. Certain precautions must be taken when using a piezometer to ensure proper usage and the accuracy of results. Here are some of them: Have the right equipment – Invest in a state-of-the-art piezometer that uses a proven method of converting fluid pressures on the sensitive diaphragm into frequency signals which are ideal in the demanding environment common with civil engineering applications. Modern piezometers are capable of long distance signal transmission without degradation. They can tolerate wet wiring conditions and resist external electrical noise, too. Some manufacturers make piezometers specific for different applications, for instance, you should be able to find one with a heavy-duty body that can be b
