Effective Tools Used To Test Your Building Strength

Image
The type of tools you will need to test the concrete structure largely depends on the types of tests or evaluations you need to meet building standards and follow common construction practices. The following are some of the most common testing ways used by testing services, engineering firms, developers, and builders whenever building or testing: •    The Rebound Hammer Test – This test is performed to estimate the compressive strength of concrete using a rebound hammer. The rebound produced by aspring-loaded mass depends on how hard the stricken surface is. When the plunger of a rebound hammer is pressed against concrete, the mass, which is spring-controlled, rebounds—the extent of which depends on the hardness of the surface. The rebound value is taken and read from a graduated scale designated as the rebound index. This can be read directly from a graph on the body of the rebound hammer. •    The Core Cutting Test – This test is a partially ...

Know More About Piezometer – Pros And Cons!

Image
Piezometer is an instrument used to measure the pressure of fluids or ground water at a specific point. Vibrating Wire piezometers use a gland and a vibrating wire sensors to measure this pore pressure. The primary use of a piezometer is to determine the pressure of ground water at a particular point or any other fluids such as, for instance, in a digging well of an extraction plant. Since the equipment gives the instant pressure and allows the data to be logged over time, it is helpful in monitoring the fluid pressure in many applications. Piezometer are used extensively in the geotechnical industry in determining the level of ground water. This is very helpful when monitoring the ground conditions around construction or infrastructure such as tunnels. Other applications include the use of piezometer on construction sites, for gauging the ground water pressure before digging up the ground for erecting a structure.   The instrument is highly efficient in de...

Applications of Ultrasonic Pulse Velocity Testers

Image
The advance mention technologies have brought in a sea change to the world of construction. The ultrasonic pulse velocity tester is one such instrument, and one of the longest established non-destructive tests for concrete. It provides a general measure of concrete quality, can be used to examine cracks depths, or locate voids, delamination and bad consolidation problems within concrete.  Most importantly, the features of this test method allow an operator to examine the concrete internal structure with no surface damage or destructive testing. Irrespective of the age of the building and size, ultrasonic pulse velocity tester accurately examines the condition of the building. There are wide spread applications for this instrument. It may be used to assess the homogeneity of materials including concrete and mortars. UPV results have acorrelation to strength and moduli of materials. A relationship has been established between UPV results and the depths of cracks pe...

What Is Concrete Geometry Testing and What Are Its Benefits

Image
Since structural condition is of great concern to owners and users it is necessary to understand what lies inside them and where. Concrete geometry testing refers to the ability to find the location of steel reinforcing, post/pre tensioning, or conduits in concrete, or to measure the dimensions of a concrete element. Applications could include drilling a penetration (core) into a concrete slab, measuring the thickness of a slab or measuring the length of a pile. There are a lot of advantages associated with geometry testing of concrete. For instance, the thickness of a concrete element and its width are some of the major measurement indicators required during design and construction. With equipment capable of measuring concrete thickness, like the concrete thickness gauge, it becomes much easier and quicker to proceed with the work. The equipment is so portable that one can easily carry it to the specified testing area on a construction site. Advanced concrete geometr...

Instruments Used for Pile Integrity Testing and strain measurement

Image
A driven pile or a drilled shaftfoundation forms the basis of the building and any deformities or cracks in them can reduce their bearing capacity and ability to support the structure. There is testing equipment that can help in detecting these cracks or voids and prevent any damage to the whole structure. Selection of the right testing technique, preferably prior to the construction of the foundation is vital to analyse foundations for the presence of defects. Piles or shafts in a construction act as support for the building and any major cracks or soil inclusionspresent in them is considered to be a defect. Location and extent of these defects can be evaluated with pile integrity testing equipment. Pile integrity testing, also known as sonic echo testing measures the effect of a strike to the top surface of a cast or driven pile. An accelerometer and geophone record the effects of the strike. Both the depth of the pile, and the position of any defects can be ev...

Benefits of Using Concrete Thickness Gauge

Image
It is now much easier to measure the thickness of your concrete slab, thanks to the non-destructive concrete thickness gauge. This digital, portable equipment is a blessing for all engineers and builders who would like to have their concrete thickness measured without damaging the surface of the material. The concrete thickness gauge comes with a lot of benefits.   Apart from being cost effective and user- friendly, this equipment does not need much care in terms of special maintenance. Non-destructive technique – This thickness gauge replaces the older technique of finding the thickness by drilling and hitting at the concrete structures. Not even a minuscule damage can be seen on the surface of the concrete after the testing is completed. Easy calibration – Concrete thickness gauges do not require the regular calibration for every test. The equipment can be calibrated by gauging the thickness of a known concrete, just before using it to test an unknown on...
