Material Testing Equipment

Concrete structures are a great deal more than sand, gravel, cement and water stirred up and left to harden into usefully shaped lumps. Considerable care and knowledge are required to produce quality concrete. We propose a complete range of testing equipment to satisfy practically all the EN and other National Standards.

Compression & Flexural Testing

The ADVANTEST 9 Compression Testing Machine can control up to 4 hydraulic testing frames, of various dimensions and capacities, to perform tests under controlled speed of:

• Load/stress (e.g. MPa/s; kN/s; etc.)
• Displacement (e.g. µm/s; µm/s)
• Strain (e.g. mstrain/s).

• Concrete post peak residual strength
• Concrete fracture toughness, from the complete Hardening + Softening Load vs.Strain diagram
• Determination of the Elastic modulus.

Cement Compression & Flexure Testers

These machines, featuring a very rigid two column frame, have been designed for the testing of the cement prism either in compression or in flexure. These frames are fitted respectively with EN compression bearing plates and EN compression bearing plates plus flexural jig.

Automatic Testing systems for Cement

Test laboratories that examine the mechanical properties of building materials require Advanced Test Systems that guarantee a high degree of accuracy and compliance to the reference Standards. They also require user friendly equipment, rapid set up and execution, automation, flexibility, and the possibility to integrate with an existing network so as to create a comprehensive data storage and management procedure.

The testing systems consist of a control console including hydraulic pump and circuit, electrical/electronic apparatus and strength measurement system, connected to 1 to 4 different frames. Different testing software can complete the testing system.

Non Destructive Testing

Strength Testing

Rebar Location

R-Meter MK III represents the re-birth of a classic rebar locator. It utilizes the latest in eddy current sensing and microprocessor technology to accurately locate, determine depth, and estimate diameter of metal objects in concrete. 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 tendons, copper tubing, conduit, and more.

Ultrasonic Testing

The V-Meter is widely used and accepted for quality control and inspection of concrete. It can measure and correlate concrete strength to standard strength measurement, permitting non-destructive testing of complete structures. It will identify honey-combs, voids, frozen concrete, cracks and other non-homogenous conditions in concrete. It is also used for testing of wood nondestructively, to detect knots, shakes, delamination, checks, splits, grain orientation, windfall cracks and presence of decay and rot.

Corrosion Testing

Gecor-8 is the world’s most advanced system for analyzing corrosion of concrete reinforcing steel in existing structures. Both the classical corrosion potential as well as the resistivity of the concrete can be measured. Advanced modulation confinement technique precisely measures the true polarization resistance of the steel reinforcing bar. The Gecor 8 also has the ability to measure corrosion rate in submerged or very wet structures.

Testing of Fresh Concrete

The M-METER, using modern microprocessor technology, applies the proven relationship of time and temperature to concrete strength for monitoring poured concrete at the site. This improves safety, ensures quality and reduces cost. The maturity method is a technique for predicting strength based on the temperature history of the concrete. Strength increases as cement hydrates. The extent of the cement hydration depends on how long the concrete has cured and at what temperature. Maturity is a measure of how far the hydration has progressed.
