Concrete Test Hammer

Original Schmidt

The quality of concrete is mainly judged by its compressive strength directly affecting the load-bearing capacity and durability of concrete structures. Proceq invented the Original Schmidt, the world’s first and now most widely used test hammer for analyzing the compressive strength of concrete properties.

The Original Schmidt will hit the concrete at a defined energy whereas its rebound is dependent on the hardness of the concrete and is measured by the instrument. The Original Schmidt is available in models with different impact energies, each test hammer designed for a specific test application, in order to meet the needs of the customers to investigate a wide range of material types and sizes, such as bridge decks, thin walls, cast stone components or small components.

Schmidt OS-120

The Schmidt OS-120 Pendulum Hammers are designed to test on softer material such as light weight concrete, gypsum boards, fresh concrete and the mortar of joints in brickwork. Their unique design allows easy to handle measurements on vertical and horizontal surfaces.

Schmidt OS-120 is the only rebound hammer worldwide working with the pendulum system, thus it must not be loaded on the test surface. The larger plunger surface on the Schmidt OS-120PT allows tests on soft concrete starting with a compressive strength of 1 MPa.

Digital SilverSchmidt

The SilverSchmidt ST/PC is the first integrated concrete test hammer featuring true rebound value and unmatched repeatability. Two factors contribute to the improved performance of this concrete test hammer over its predecessors:

Ultrasonic Pulse Velocity (UPV)

Ultrasonic Pulse Velocity (UPV) testing of concrete is based on the pulse velocity method to provide information on the uniformity of concrete, cavities, cracks and defects. The pulse velocity in a material depends on its density and its elastic properties which in turn are related to the quality and the compressive strength of the concrete. It is therefore possible to obtain information about the properties of components by sonic investigations.

Proceq offers the most versatile instrument for ultrasonic Pulse Velocity (UPV) testing of concrete – the Pundit Lab, the newest member of the famous Pundit family. Along with the traditional transit time and pulse velocity measurement, this ultrasonic concrete testing equipment offers path length measurement, perpendicular crack depth measurement and surface velocity measurement.

Control buttons and optical feedback directly on the probe increase measurement efficiency and make to instrument even more user-friendly.

Rebar Detection

To allow certain constructions and to strengthen the concrete rebars are cast into it. Drilling through those reinforcing bars is a costly business that can be dangerous: Hitting a rebar while boring into the reinforced concrete can destroy the drilling instrument and can severely weaken the concrete structure. An instrument for rebar detection that quickly and accurately determines the location of the reinforcing bars in the concrete will significantly decrease construction time and costs.

The rebar detection instrument Profoscope has a unique real-time visualization mechanism, allowing the contractor to actually see the location of rebars beneath the concrete surface. The Profoscope+ features data storage for automatic collection of data to make rebar detection more efficient.

The Profometer PM-6 combines rebar detection and measurement of concrete cover and bar diameters in one instrument.

Corrosion Monitoring

Since reinforced concrete will be subject to a corrosion process that ultimately leads to a total failure of the structure, corrosion monitoring is essential. In the first stage, aggressive elements penetrate into the structure. On reaching the rebars, high concentrations of those elements attack the passive layer of hydrated iron oxide that protects the rebar against corrosion. Rust begins to form which eventually leads to structural failure. Early diagnosis and monitoring of seemingly healthy concrete cover allows pre-emptive corrosion control measures to reduce unwanted risks.

The Canin+ is an instrument for corrosion monitoring allowing rapid, comprehensive tests of the site and provides a assessment of locations where corrosion is likely to take place before the rust becomes visible. This corrosion monitoring allows the user to reduce the costs of corrective maintenance significantly.

Canin+

Corrosion Analysis allows the contractor to limit the maintenance tasks on reinforced concrete to the areas where it is really required. The Canin+ is the fastest instrument for corrosion analysis, offering a practical, cost-effective approach to the investigation of reinforced concrete. Corrosion analysis with the Canin+ allows a rapid, comprehensive test of the site and provides a fast assessment of locations where corrosion is likely to take place. Corrosion analysis with the half-cell potential method: accurate field potential measurements aid in detecting active corrosion in rebars.

Permeability Test

The permeability of concrete at the surface is a major factor in determining the durability of concrete structures. A reliable permeability test of the concrete cover is therefore crucial – not only in the laboratory but also at the building site. One factor determining the durability of concrete is the ease with which air can penetrate into concrete.

The permeability test with the Torrent permits a rapid analysis of the air permeability of the cover concrete by a non destructive method. The essential features of the permeability test method of the Torrent are a two-chamber vacuum cell and a pressure regulator which ensures an air flow at right angles to the surface into the inner chamber. The permeability test with the Torrent takes only 2 – 12 minutes

Permeability Tester - Torrent

The Torrent permeability tester permits a rapid and non destructive measurement of the quality of the cover concrete with respect to its durability. Concrete permeability is an excellent indicator of the potential durability and resistance of a particular concrete against the ingress of aggressive media in the gaseous or liquid state. A measurement with Proceq’s permeability tester takes 2-12 minutes.

Pull Off Tester - DY-2 Family

The Proceq DY-2 Family of automated pull-off testers covers the complete range of pull-off applications with unmatched ease of operation and a unique capability to store a complete record of the test.

Pull-off testing is one of the most widely used test methods in the construction industry. This is reflected in the huge number of standards dedicated to the method.

It has long been known that one of the major influences on the result of a pull-off test is the operator influence in the application of a constant load rate. The DY-2 with its integrated, feedback controlled motor removes this variable completely, by providing a fully automated test at a constant load rate which can be verified.
