Best and Most Effective Way of Testing Concrete Strength and Quality

 

Investigating the physical behaviours, strength attributes, and elasticity of concrete is essential for the success of a project. Utilisinga  tool to test for strength of concrete simplifies this process. The Schmidt Hammer is one such tool, and it comes in various models to suit different materials like mortar, cement and rock.

 

You can determine concrete quality by looking into the density, penetrability, modulus, and elastic properties. But what is the most effective way to test the strength of concrete? Let’s take a look at every option.

 

Original Schmidt Hammer

 

The classic Schmidt hammer is the rebound hammer, which comes with a sensor for measuring the rebound value of the test impact. The R value mechanism measures the height of the impact mass’ rebound after impact, its affected by direction so you need a upwards, horizontal and downward measurements to create curves for before crushing.

 

Silver Schmidt Live Hammer

 

The latest Silver Schmidt Hammer are Q value hammers that are a speed measurement based mechanism, they measure the impact mass’ speed before and after impact, and the Q value is a ratio of the two. This measurement has no directionality, so it can be measured at any angle, and its more appropriate for 70 or more MPa strength materials.

 

It has more benefits than the classic Schmidt Hammer. For instance, it measures using the quotient of the impact and rebound velocities, increasing the sensitivity between 10 to 100 MPa while unaffected by gravity. This way, you can operate it at 360 degrees without corrections. It’s possible to increase the range to 5 to 100 MPa with the Mushroom Head for the Type L variants.

 

The Schmidt hammeris a lightweight digital unit that can connect directly to an Android or iOS device to log data, create custom curves, and perform other actions in real-time.

 

Ultrasonic pulse velocity testing equipment

 

UPV testing equipment provides a non-destructive and quick way to determine the strength and consistency of concrete. It also helps locate damage or voids in columns, walls, and beams and may be useful in measuring the depths of cracks in the material. The latest devices have a touchscreen display and are compatible with an ultrasonic pulse-echo transducer, making them practical for more applications, such as identifying concrete’s homogeneity and quality in relation to specified standards.

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
