A look into Concrete Compression Testing

The concrete compression test is conducted to determine the compressive strength of concrete structures. In a concrete compression test, a concrete specimen is formed into a cylinder or cube, allowed to set for a period of time and then tested in a laboratory using a specially designed machine. The size of the specimen depends on where the test is conducted. For instance, 150mm cubes are the norm in European and Asian countries and in Russia, while cylinders are used in Australia and the US. 

Concrete specimens are typically created and cured for 28 days on-site before being sent to the laboratory to be tested, but there are times where the testing may occur after one, three, seven, or 14 days of curing. When the specimen is placed in concrete compression test machine, pressure is constantly applied until failure cracks appear, the machine will detect the rapid drop in pressure when a break occurs. 

There are different types of concrete compression test machines. A manual flexure and cement compression machine can be used for reliable flexure and strength tests on specimens made of mortar. Manual operation makes it ideal for on-site testing when a power supply is unavailable. The machine is easy to use, even if you lack experience in operating concrete compressing testing machines. 

Semi-automatic concrete compression testing uses a motorised machine with a single or double testing chamber for flexure and compression tests, these units record results but need an operator to control the load rating. Concrete compression testing machines come in an automatic version which will control the load rate of test automatically along with recording results.

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
