The reason behind performing the Charpy impact testing is to understand the overall energy that has been absorbed by the material during fracture. Widely called a Charpy V-notch test, the testing process involves striking a given specimen using a weighted pendulum that gets swung at a desirable height. This type of impact testing method is commonly followed in many different industries as it is the best possible way to prepare the right materials.  Widely acknowledged features of  Charpy impact testing : Charpy test showcases if a metal is ductile or brittle. These kinds of classification are highly used with the ferric type of steels, which tend to showcase them as ductile or brittle. Brittle metal, after passing through the required impact test, absorbs only minimum energy. Ductile metal absorbs higher energy levels. A generated fracture surface does provide information co-related to the type of fracture surface created through the process. The appearance is highly noted in findi

Concrete moisture meters and the measurement of accurate levels of moisture in a concrete slab is essential due to many different reasons. Within a given slab, the different areas may not dry evenly. Therefore, moisture tests are carried out for the different slab areas to ensure proper working and use. Moisture may cause the degradation of the organic flooring or other materials that may be placed on concrete. Further, it can deteriorate the quality of the flooring itself and may also invite the growth of moulds. Rebar reinforcement can also be avoided beneath the surface by measuring the moisture content of concrete using a  concrete moisture meter .   The Concrete Moisture Meters for Testing and Investigation   According to the “ASTM F2170” standard, all the concrete slabs should be tested before their installation and use for the moisture content regardless of their grade or age. A  concrete moisture meter  can check the content or moisture level at any point of the slab an

Construction and excavation work often bring the workers close to the many different underground utilities, including telecommunications, gas, electricity, water, and others. The utility locating equipment, including the advanced ground penetration radars available now, ensures that the exact location of these varied utilities is found out. The work can be carried out with the restraint, safety, and without losses. The utility locating equipment includes the transmitter and receiver, and create and spread the electromagnetic field by directing it inappropriate subsurface and beneath the ground regions. When an underground utility reflects these radiations, they are received by the utility provider's receiver, which provides for accurate and reliable work.   Detection: A Primary and Important Consideration While Using Utility Locating Equipment    Using the latest and advanced GPR or  utility locating equipment improves the probability of the accuracy of the process of dete

A coating thickness gauge is a highly precise and intelligent instrument that can accurately and quickly measure the thickness of a surface coating or plating. These surfaces may be metallic or non-metallic. The different coating thickness gauges can be used for ceramic and non-magnetic paintings, rubber coats on different kinds of materials, plastics, ferrous and nonferrous materials, and non-conductive and non-corrosive materials, and other kinds of material coatings.   The Essentiality of Coating Thickness Gauges The thickness of a coating is of paramount importance in many different aspects. A  coating thickness gauge can  be used to evaluate the life of a surface and product, where the proper thickness of the coating is essential for its longevity. It can also be used to inspect specific claims, as in the case of pre-owned cars, and can deduce the re-painted spots, among other uses and benefits. The gauge is used to measure the coating thickness on materials, including glass

  Charpy Impact Test also known as the Charpy V-Notch test, is used for measuring the amount of energy that a material absorbs at the time of fracture. The “Strain Rate” test is conducted in a standardised form, and the energy absorbed reveals a material notch’s toughness.   Factors and Variables of the Charpy Notch test   The Charpy test apparatus includes a pendulum with a known height and weight that is dropped from a given height and impacts the notched specimen. An important factor is the energy absorbed, determined by measuring the pendulum’s height before and after the impact/fracture. The size and dimensions of the notch are also important as these factors impact the test results. The test may also have several variables, as described below.           I.             Significant variations in the test results will be obtained because of the variations in the product form (for instance, plate or forging).         II.             The manufacturing process may imp

A paint thickness gauge is used to measure dry film thickness. A painting job requires precision and accurate coating technique to make it long lasting. It is necessary to gauge the right thickness of the paints to evaluate the expected life of the coating, performance, and appearance of a product, and ensure compliance with a host of international standards. The Paint Thickness Gauge is equipment which can help in ascertaining the correct layer thickness and therefore help in making the job seamless and error-free. Also, the thickness gauge does not employ any descriptive methods used before to test the paint thickness. The gauge uses electronic testing methods which are quite non-destructive and also provides cumulative results.   Tips to choose the right paint thickness gauge In industries, manufacturers use paint thickness gauge to make sure their products are of required standards. Here are what to look for when choosinga thickness gauge: ·          Type of gauge The

The CBR Test is a measure of the resistance of a material to penetration of standard plunger under controlled moisture conditions and density. The California Division of Highways developed it as a method of evaluating and classifying soil-subgrade and base course materials for flexible pavements. The test might be conducted in the undisturbed or remoulded sample. A cylindrical plunger of 50 mm diameter is used to penetrate a pavement component material at 1.25 mm/minute. Loads of 5 mm and 2.5 mm are recorded. It is expressed as a percentage of standard load value at a respective deformation level to obtain the value of CBR. California Bearing Ratio Test on Subgrade Soil The primary aim of this test is to determine the California Bearing Ratio value of the subgrade soil. Apparatus for CBR Test Any compression machine that can operate at a constant rate of 1.25 mm per minute can be used. It consists of a moulds of 150 mm and 175 mm height offer a collar of about 50 mm leng

The comprehensive strength of the concrete compression test offers an idea about all the characteristics of concrete. By this single test, one can judge whether concreting has been done correctly or not. The compressive strength of concrete for general construction varies from 15 MPa to 30 MPa and higher in industrial and commercial sectors. Compressive strength of concrete depends upon various factors like cement strength, water-cement ratio, quality of concrete material, and quality control at the time of production of concrete, among others. Test for compressive strength is carried out either on a cylinder or cube. Various standard codes recommend a concrete cube or cylinder as the standard specimen for the analysis. How can compressive strength be defined? Compressive strength can be defined as structure or material to carry loads on its surface without any deflection or crack. A material under compression tends to reduce the size when in tension, and the size elongates.

The magnetic extensometer is a system which is used for examining the settlement and heave in foundations, digging and barriers. Settlement occurs at the depth or the position and is identified there. It is there only where the settlement is measured. The soil extensometer incorporates magnetic targets that are placed so that they can move freely outside the access case or inclinometer case which is flush joined. The 3 or 6 Leaf Spider, magnetic settlement plates or magnetic joints can be the targets. The relative position of the magnetic targets is used for measuring the settlement. This is done by using a Reed Switch Probe which helps in identifying the magnets which are lowered down through the central access casing. Features This device helps in the total and the progressive settlements too. The Following are the characteristics of a magnetic extensometer that are used in the task of excavation. Convenient handling As an alternative to the measuring tape, the magne
