View inside the Cheops Pyramid

Geophysics doctoral student Johannes Scherr reports from Egypt

One of the best researched buildings of antiquity: the Cheops Pyramid. Still, its structure has not yet been investigated in its entirety. Using non-destructive testing methods, doctoral student Johannes Scherr took a closer look at the inside of the pyramid. For us he wrote down his experiences:



From Hydrophobic Concrete to Towering Pyramids  – Interview with Professor Große

Online Artikel in REISSWOLF, the Periodical of the Student Association for Mechanical Engineering

An interview with Professor Christian Große about the TUM Chair for Non-destructive Testing: What do concrete with bacterial spores, a BMW Wendler and pyramids have in common? They all were all examined by Professor Große using nondestructive testing methods. The measurement technology is particularly interesting and ranges from Georadar to Computer Tomography. Professor Große founded and built the Chair for Non-destructive Testing in 2010 with only two staff members. Today, the Chair has over 20 employees and his research has lead him to the most unique investigations.



New Data about the structure of the Pyramid of Cheops

Interview with Prof. Christian Große on the ScanPyramid project team’s investigation of the Pyramids of Giza

Measuring a height of 139 meters (455 ft.), the largest of the three pyramids of Giza is one of the oldest edifices in the world. Yet, even after 4,500 years, this architectural masterpiece still leaves some questions unanswered. Christian Grosse, Professor for Non-destructive Testing at Technical University of Munich (TUM) has performed fascinating measurements at the Pyramid of Cheops in coordination with Cairo University. In this interview, he presents his experiences.

In cooperation with the Chair of Non-destructive Testing and the Chair of Conservation-Restoration, Art Technology and Conservation Science of the TU Munich as well as the Fraunhofer Institute EZRT - Fürth, the Deutsches Museum examined a Messerschmitt Me 163 "Comet". The museum wished to examine various components, surface paint, and internal construction without having to disassemble the plane.

The Chair examined the aircraft using various nondestructive test methods, including Lock-in infrared thermography, flash thermography, phased-array ultrasound, eddy current and video endoscopy.

The Chair took thermographic images used in the November/December 2014 edition of the magazine "aktiv Radfahren." The images were used to evaluate the insulating properties of winter clothing for cyclists while in a cold-chamber.


Nov. 2014 - Nov. 2018

The chair was a member of the COST TU1404 project from November 2014 - November 2018, “Towards the next generation of standards for service life of cement-based materials and structures,” which is funded by the European Commission. The basis for a modern and reliable quality assurance tests for fresh concrete were established. The project coordinator is Prof. Azenha, University of Minho, Portugal. The Chair of Non-destructive testing worked closely with Work Group WG 1 - Testing of cement-based materials, which was led by Prof. Trtnik (IGMAT Building Materials Institute, Ljubljana, Slovenia) and dealt with interlaboratory-tests where the suitability of various NDT tests (including ultrasound) for fresh concrete analysis were evalated.

Excellence-cluster MAI Carbon starts Projekt MAIzfp:

Kick-off in Munich-Pasing


Partner of the project MAIzfp

On the 1st of March the joint project "MAIzfp - Combined non-destructive testing for quality control of composite materials" has launched as a part of the BMBF-funded cluster of excellence MAI Carbon. Through the joint research of the chair with different industrial and research partners competences are brought together in the field of non-destructive testing of CFRP materials. The objective is to improve the confidence level of both individual NDT methods and their combination to ensure an economical manufacturing process for composite materials.



Partner of the EU project HEALCON

Since 1st January 2013 the Chair is a partner in the EU project HEALCON (Seventh Framework Program). The goal of the projet HEALCON is to produce a smart concrete with self-healing properties in order to enhance the durability and sustainability of concrete structures (for example, concrete infrastructure). The Chair of Non-destructive Testing, in cooperation with the other project partners, is developing a test and monitoring protocol using a variety of NDT methods to observe the healing mechanisms and to assess the condition of the concrete.
