Concrete Compression Testing
Concrete compression testing machines are essential tools in the construction industry, used to test the strength of concrete. These concrete testing machines measure the compressive strength of hardened concrete specimens, determining whether the concrete used in construction projects meets the minimum required strength.
First, you need concrete cylinder molds to shape and hold fresh concrete specimens during the casting process. These create cylindrical samples and facilitate concrete curing. Our complete line of concrete cylinder molds is constructed from the best steel materials and has an unlimited shelf life, whereas plastic concrete cylinder molds are designed for disposable use. Each set comes with multiple molds per case, with the most popular options including 36, 50, or 80 per case.
Then, you add the hardened specimens from the concrete cylinder molds to a compression testing machine.
Compression testing machines work by applying a compressive force to concrete until it fails. The failure point determines the compressive strength of the concrete.
Types of Compressive Testing Machines for Compression Test Methods
These machines come in a variety of sizes and capacities, depending on the size of the specimens being tested and the amount of force required. Often, you’ll find them in laboratories and in the field on construction sites. They are usually constructed from Teflon load frame and steel load frame, with a lactchable steel guard door.
There are two types of concrete compression testing machines: hydraulic and manual. Hydraulic machines are more common in construction projects because they offer more accurate results and require less effort to operate. They use hydraulic pressure to apply the necessary force to crush the concrete specimen.
Manual machines, on the other hand, require the operator to turn a hand crank to apply the force. As a result, they’re less accurate and more labor intensive.
All of our concrete compression testing machines can be fully equipped with high-accuracy and easy-to-use Pro or Pro-Plus digital controllers. Both exceed industry standards for accuracy, making it easier than ever to produce exceptional concrete. In addition, all of our sturdy concrete compression machines meet or exceed ASTM C39 and ACI 368 recommendations, as well as international standards and EN 12390, for rigidity in the concrete compression test methods.
The Pro Controllers display and the Pro Plus Controllers with the Pro Plus features options provide live load and rate of final load during compression tests by the compression machine, and each are accurate to ±0.5%. Peak load and average load rate are shown at the end of the test, and up to 600 tests can be stored in memory for you to download to a PC or printer.
Not only are results automatically stored, but the Pro-Plus also performs live X-Y plotting of load vs. time. There are also options to send data to a printer for custom printing, plotting, and reporting.
The compression testing machine with automatic controllers are a new addition to compressive strength tests. These automatic controllers perform complete test cycles on concrete strength specimens with minimal operator input.
Why Use Concrete Compression Tests with Compression Machines?
Using concrete compression testing products is crucial for ensuring the safety and reliability of construction projects. If the concrete used in a project is not strong enough, the structure can fail, leading to property damage, injuries, or even loss of life.
Regular testing of concrete with compression machines throughout construction helps to identify these issues early on, allowing for corrective measures before completing the project.
Concrete Compression Testing Machines Overview
Concrete Compression Testing Machines are specialized devices designed to evaluate the strength of concrete, which is typically measured in pounds per square inch (psi). These machines operate by applying controlled, increasing force to a concrete sample until it fractures, thereby determining its maximum strength. The process involves several key components and concepts:
Concrete PSI Tester: This is a central feature of the machine, designed to measure the pressure or force exerted on the concrete sample in psi. It provides an accurate assessment of the concrete's compressive strength.
Device to Test Concrete Strength: The entire setup of the compression testing machine serves as a device to test concrete's strength. It usually includes a hydraulic press and a load-bearing platform where the concrete specimen is placed.
Calibration of Cube Testing Machine: Calibration is crucial for ensuring accurate measurements. Cube testing machines, which test the strength of concrete cubes, must be regularly calibrated to maintain precision. This involves adjusting the machine to a standard set of measurements or using known weights to verify accuracy.
Compression Test on UTM Machine: UTM, or Universal Testing Machine, is a versatile device capable of conducting compression tests among other types of mechanical tests. When used for concrete, it applies a compressive load to the material to measure its strength and deformation characteristics.
Compressive Test Fixture: This is a component of the machine that holds the concrete sample in place during testing. It ensures the uniform application of force and accurate measurement of the sample's dimensions and integrity.
Universal Testing Machine: This is a broader category of testing machines that includes the capability for compression testing. UTMs are known for their versatility in performing various types of material strength tests, including tension, compression, and bending tests.
Load Cells: These are critical sensors in a compression testing machine. Load cells measure the amount of force applied to the concrete sample. Their accuracy is vital for reliable test results.
Load Cell: Singular form of load cells, it refers to the individual sensor used in the testing machine for measuring force.
Proving Ring: This is a device used in the calibration process. A proving ring is a steel ring with known force-deformation characteristics. It is used to calibrate testing machines by correlating the force applied with the deformation observed.
Calibration: This refers to the process of ensuring that the testing machine provides accurate readings. Calibration involves checking and adjusting the equipment with standard measures or known loads to ensure the results are accurate and reliable.
Overall, Concrete Compression Testing Machines are essential in determining the structural integrity and load-bearing capacity of concrete, playing a crucial role in construction and safety. Regular calibration and maintenance of these machines are vital to ensure their accuracy and reliability.
