Concrete Testing Equipment
The word concrete comes from the Latin word "concretus" that means compact or condensed; in fact it is well known that since the second century the Romans mixed quicklime with pozzolana to enhance its hydraulic properties.Concrete is a composite construction material made primarily from aggregate, cement, and water in order to obtain a robust stone like material. There are many formulations of concrete that provide various properties. Concrete is the most widely used man-made product in the world as the main building material within architectural structures, foundations, brick/block walls, pavements, bridges/overpasses, motorways/roads, runways, parking structures, dams, pools/reservoirs, pipes, footings for gates, fences, poles and even boats.
The quality of concrete is important in planning earthquake resistant structures that minimize damage, preventing injury and human loss.
Due to this reason, concrete must be closely controlled according to the relevant standards in every stage of production by experienced people using quality test equipment.
Pile Integrity Tester With Tablet Overview
The PET (Pile Echo Tester) uses the Pulse-Echo method (PEM) for quick pile integrity test (quality control) of a large number of piles.The pile top is struck with a lightweight handheld hammer. The reflected wave is captured and analyzed by the PET's digital accelerometer to provide information regarding the length and shape of the pile. The PET is fully compliant to ASTM D5882-16: Standard Test Method for Low Strain Impact Integrity Testing of Deep Foundations for pile integrity testing as well as additional standards PET hardware connects to any portable PCs. The Bluetooth version also connects to any Android device (phone, tablet). The PET package includes all software versions: for PC and for Android. All versions are included and operate in full compatibility.

Possibility to use the instrument with two exponential probes, or with one standard probe and one exponential probe.The use of the appliance is made easy because it is based on PC and Windows CE way of working, it allows using the user knowledge of the classic personal computer and its software’s.Possibility to connect the instrument to internet for consultations or extractions, like a common PC. Possibility to visualise the shape of the transmitting wave while it goes through the material checked, by transforming the instrument into a real oscilloscope with the option “Scope” mode.
Combined ultrasonic and rebound hammer determination (sonreb method): The ultrasonic tester houses an integral data logger for data acquisition, processing and store of rebound hammer values. The acquisition of the rebound values is performed with manual or automatic mode.
a) Manual mode:
Rebound values measured with a standard concrete hammer are manually input into the ultrasonic Tester.
b) Automatic mode:
The digital test hammer model is directly connected to the ultrasonic tester through a cable.
The measures of the velocity of ultrasonic pulses and the rebound values are automatically stored and processed, giving estimates of dynamic modulus of elasticity and Poisson’s Ratio, and providing information’s on possible voids, cracks and strength of the structure.Through mathematical formulas it is possible to evaluate the compressive strength of the concrete, useful to estimate formwork striking times.
The combined test allow to rectify different inaccuracies that are typical of the simple rebound hammer test, and obtaining estimates on the compressive strength of the concrete, that cannot be obtained with the ultrasonic test, granting high accuracy and reliability of the results.
The standard appliance includes:
• Instrument in basic configuration (x-scale 400MHz, 64MB Flash Memory, 64 MB Ram) in a practical and elegant palmer container.
• Two 55 kHz probes with connecting cables.
• Calibrating cylinder and contact paste
• Strong anti-shock case holding the instrument and the accessories.
• Battery pack Li-Ion 11,1V 3000 mA/per hour
• External feeder 230V/24V and battery charger

This is a rugged digital hand-held field instrument for finding the location and depth of reinforcement bars in place. This is light weight and inexpensive, and an easy to use unit to locate rebar. Rebar detection of up to 10"Diameter (250mm) can be accomplished when locating large diameter rebar. An easy to read display and a 4 Hr battery life are just a few advantages that make this one of the most advanced hand held units in the field today. The sensor design allows the end user to quickly and accurately locate and determine concrete cover in corners or hard to reach areas. The system allows the user to select between Imperial and Metric units, and the data can be saved in the instrument for posterior uploading to a computer. The data is saved in the system with the date and time of the record to help identify prior test taken. The Mini R-Meter rebar locator is also capable of locating non-ferrous metals. The eddy current sensor was specifically designed to react with the presence of currents on the outer surface of metal objects. It is uninfluenced by small metal particles in the concrete, whether the concrete is fresh or hardened, wet, or dry. The eddy current sensor also allows the unit to locate both ferrous as well as non-ferrous metals in concrete; thereby finding not only steel reinforcing bars accurately, but also tendons, copper tubing, conduit, and more. The latest in microprocessor technology not only conditions the signal from the sensor for more accurate and dependable results, but also provides the user with the information they need. Built in memory can store over 150 individual data points for later processing.
Measurement of Concrete Cover
The exact position and orientation of rebar can be measured quickly and accurately. Knowing the size of the rebar, concrete cover can be detected and the distance between the concrete and the surface it will appear in the easy to read display.
