Papworths Construction Testing Equipment

Soil testing is a mandatory task for construction companies because it lets them predict the mechanical behaviour of soils which will become the support for infrastructure and roads or serve as the base of foundations for buildings. To save time and effort, construction companies must invest in high-quality soil testing equipment that is suitable for characterising soil samples in laboratories. Likewise, they must consider using high-end on-site testing equipment. Many different types of soil testing equipment support soil classification, the collection of soil samples, the evaluation of soil’s mechanical properties, and the testing of completed sub bases and road bases on site. Construction companies rely on soil testing equipment to examine the geotechnical and chemical properties of soil. They can determine if the soil is suitable for the construction project and if it can accommodate the building in the long run. Soil testing equipment is useful in identifying the kinds of so...

Checking the quality and durability of natural rocks and concrete is essential to ensure the stability and strength of a structure. To do that, you need to conduct an ultrasonic pulse velocity test, a non-destructive and in-situ testing method that assesses the quality and strength of concrete or rock. In this test, the velocity of the ultrasonic pulse through a concrete structure is measured. An ultrasonic pulse velocity test is conducted by letting a pulse of ultrasonic wave pass through a known distance of material, then measuring the time it takes for the pulse to go through the structure. A higher velocity pertains to a high-quality and durable material, while slow velocities may indicate defects like voids and cracks in the concrete or less dense materials. An ultrasonic pulse velocity test can be conducted quickly with more reliable results with the right testing equipment. Testing machines typically have a pulse generation circuit and a pulse reception circuit to receive ...

The right equipment can make it easier to examine and determine the quality of concrete. Ultrasonic pulse velocity testing equipment is one of the most essential instruments that you can use for conducting tests on concrete. High-quality ultrasonic concrete testing equipment offers data acquisition, complete control of transmission parameters, and waveform analysis. It can conduct conventional pulse velocity and transit time measurements, as well as surface velocity, perpendicular crack depth, and path length measurements. High-end ultrasonic concrete testing equipment comes with an optimised pulse shaping for better transmission range, even with lower voltage levels. Together with automated receiver gain and transmitter voltage, the equipment ensures optimum signal levels for stable and accurate measurements.  Modern ultrasonic concrete testing equipment is a touchscreen unit that can control traditional ultrasonic pulse velocity transducers and pulse echo transducers. A mat...

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 machine...
