Acoustic emission analysis (AE) in civil engineering

Division:

Civil Engineering

Department:

Building preservation

Description:

Damage to a structural part occurs under mechanical or thermal stresses. The cracking releases elastic waves in the material. These waves can be detected with a suitable transient recorder and extremely sensitive sensors. Using a suitable measuring device, we can determine the source of the signal and thus the location of the damage - even before it becomes visible to the human eye on the surface or before the component as a whole is damaged. We can use our measuring equipment for laboratory tests as well as on site at your project.

Magnetic leakage field measurement

Division:

Civil Engineering

Department:

Building preservation

Description:

Prestressed concrete structures owe their high load-bearing capacity and concurrent slim design to the integration of pre-stressed steel reinforcement. In most structures, this steel is embedded into the concrete and therefore not visible from the outside. It is thus not easily accessible for inspection. At the MPA University of Stuttgart, our engineers and scientists have developed a test method based on the applicaton of a magnetic field, that can be used to inspect the embedded prestressing steel for damage, especially fractures. Direct contact with the reinforcement is not necessary. This test is particularly relevant for the assessment of bridges in existing structures (recalculation guideline), but also for other long-span structures, such as gymnasiums and other halls. Further information on the test method can be found here.

Material moisture analysis

Division:

Civil Engineering

Department:

Description:

The knowledge of material moisture is of outstanding importance for the repair and preservation of historical buildings and structures. Our experienced field service team can carry out in situ measurements on your premises or take appropriate material samples, determine all necessary moisture-related parameters in the laboratory, and evaluate the results.

The water absorption behaviour of natural stone and other weathered materials is decisive for assessing the weathering behaviour. We determine the water absorption behaviour of your object in situ using capillary water absorption (test tube according to Karsten). We carry out capillary water absorption on building material samples of your object according to DIN EN 772-11.

Investigation of hygroscopic sorption properties according to DIN EN ISO 12571 on porous building materials with the reference method (desiccator method) and using a computer-controlled climate chamber, GraviSorp 120. Due to the possibility of setting small step sizes between 1% r.h. and 98 % r.h., we can record sorption isotherms and, for example, evaluate the damage potential of salts harmful to building materials.

Reinforcement scan

Division:

Description:

There are often no or only insufficient reinforcement plans for existing buildings. Our competent employees have a choice of different measuring methods to determine the position, amount and diameter of the existing reinforcement with non-destructive or minimally invasive test methods. Subsequent examinations, e.g. regarding corrosion, are carried out in cooperation with our colleague experts.

Salt pollution and salt reduction measures ("desalination")

Division:	Civil Engineering
Department:	Building preservation
Description:	Knowledge of the extent, concentration and type of salt contamination is essential for the preservation of historical objects and especially of buildings made of natural stone. Our experienced team uses mobile non-destructive test methods (e.g. Raman and near-infrared spectroscopy) to determine the near-surface salts. By sampling and laboratory investigations (e.g. ion chromatography and X-ray diffraction) the salt load is further verified, quantified and evaluated. The use of salt reduction methods aims at reducing the concentration of salts harmful to buildings in mineral building materials as non-destructively as possible. A reduction of the salt content is often a mandatory prerequisite for sustainable restoration measures: The formation of salt crystals is stopped or slowed down or the implementation of further measures, such as stone consolidation, is made possible. Salt reduction is achieved, for example, by compress desalination or the vacuum suction method. We support you in the evaluation of the success and estimation of the expenditure by analytical examination.

Structural monitoring (SHM)

Division:

Civil Engineering

Department:

Building preservation

Description:

A precise damage analysis of structures may require the consideration of time-dependent influences and loads. These include, for example, temperature, rain, solar radiation or mechanical loads from traffic and wind. With the help of a suitable structural health monitoring system, the origin of existing damage can be determined and future damage may be avoided. Our engineers will design a suitable concept with you and install and operate a monitoring system adapted to your needs, with classic electro-mechanical or fibre-optic sensors, wireless or wired. Find more information on the linked detail page.

We monitor for you:
• Displacements, deformations and crack widths
• Strains and forces
• Shock and vibration according to DIN and ETSI
• Loads, temperature, humidity and other influences
• Material moisture and salt load
• And many more

Description:

We use the methods of thermal analysis (DIN 51005) to study temperature-dependent material properties. We determine typical parameters for material characterization, such as decomposition temperatures, temperature stability, oxidation stability, quantitative composition, transformation temperatures and enthalpies with simultaneous thermal analysis (Netzsch STA 409). We determine glass transitions with the differential scanning calorimeter Mettler DSC 822.

Description:

Infrared thermography is an extremely helpful tool in building physics for quickly examining large areas. We use it on your buildings to find thermal bridges, make hidden structures visible, or localize moisture spots and leakages. Our modern infrared cameras have excellent temperature resolution, allowing us to detect even the slightest temperature differences.

Transmission Electron Microscopy (TEM)

Ultrasonic measurement array (civil engineering)

Ultrasonic measuring system for mineral building materials

Ultrasonic testing in civil engineering

Division:

Civil Engineering

Department:

Building preservation

Description:

Used for non-destructive testing of mineral, metallic and other solid materials in the construction and engineering industries. The object to be examined is sounded with acoustic waves. The reflected or transmitted wave is recorded and evaluated with regard to transit time, wave form or frequency content. Our experts can draw conclusions about material thickness, inhomogeneities, inclusions and embedded components, delaminations, material moisture and much more. We offer the performance of the measurements in the laboratory and on site.
