Girlsday 2024

For this year's Girls' Day, the event was relaunched under the motto "Introduction to the world of concrete" and expanded thematically.
Schoolgirls were given the exciting opportunity to experience the diversity and possible applications of concrete up close and with their own hands during a visit to the laboratory.
with their own hands.

Particularly impressive was the independent production of miniature versions of the RUB campus landmark, the Audimax, from colored mortar.
This gave the students a first insight into the possibilities opened up by digitalization and the interdisciplinary connection of civil engineering with other technical fields.
construction with other technical fields.

In order to produce the negative mold for the miniature editions, a CAD model was created in advance based on drone images of the lecture hall.
This model was then 3D-printed and ultimately formed the template for the production of the reusable silicone formwork.

Another focus was on the optimization potential of concrete with regard to climate change and the scarcity of resources.
It was shown which approaches exist or are still required in order to meet future challenges.

The workshop was organized and carried out in cooperation with the Press and Public Relations Department of the Faculty of Civil and Environmental Engineering
and the Institute of Concrete Structures.

Girl's and Boy's Day 2023

This year, after a two-year break from Corona, Girls' and Boys' Day finally took place again. The Chair of Building Materials Technology was again represented with a workshop under the motto "Concrete is colorful!" The title deliberately refers to the diversity of concrete as a building material.

Within the scope of the practice-oriented workshop, the students were given insights into the diverse properties and possible applications of the material. In addition, they were given the opportunity to deal creatively with the design diversity of concrete as a building material, to produce it independently and to test the fresh concrete properties.

At the same time, the diverse tasks of a civil engineer's day-to-day work were also conveyed. Afterwards, the concrete produced could be colored independently with color pigments and poured into a wide variety of shapes. As a souvenir of this year's Girls' and Boys' Day, the participants were allowed to take home the freshly made "artificial stones". These now have to harden in the formwork after one day and can then be stripped by the participants and treated accordingly with the newly acquired knowledge.

The Chair of Building Materials Technology would like to thank the Junge Uni RUB for the excellent organization.

More information about the Girls' and Boys' Day and further offers for pupils can be found here and here.


Bridge construction site A44 near Kassel

Last week, employees from the Chair of Building Materials Technology accompanied the concreting of the superstructure of a new bridge being built on the A44 near Kassel. The construction project is being carried out by the Josef Raedlinger Group of Companies.

The reason for this was, on the one hand, the validation of modified fresh concrete testing methods under construction site conditions within the framework of the AiF e.V.-funded research project "Processing of fresh concrete surfaces - development of adequate testing methods for the early evaluation of fresh concrete" (IGF project no. 21499 N).

On the other hand, test specimens as well as a demonstrator slab were produced on site, which serve the subsequent investigation of the chloride penetration resistance, the carbonation depth as well as the compressive strength within the scope of the AiF e.V.-funded research project "Durability according to the Performance Principle" (IGF project no. 21823 N).

Student internship

As part of the long-standing cooperation with the Alfried Krupp School Laboratory, the student project "Concrete Corrosion and Rehabilitation" took place again at the beginning of March. The project represented the conclusion for a seventh grade class of their series of lessons on the subject of historic preservation and building restoration and offered the students the opportunity to deepen their previously learned knowledge through the practical application of common restoration methods.

The first port of call this time was the GC building on the RUB campus, which is a listed building and has been decommissioned for imminent demolition. Together with the project manager responsible for the demolition, they were able to examine the building fabric and the interaction of concrete and steel in the composite material reinforced concrete. They used non-destructive measuring methods such as the rebound hammer to determine the concrete compressive strength and the profometer to determine the position of the reinforcement under the concrete cover.

The students then determined the carbonation depth of various structural components in the exterior of the building and took concrete samples for a moisture measurement using the calcium carbide method. At the Institute for Structural Engineering (KIBKON), trained building material testers demonstrated this method and then assisted the students with a complete repair of reinforced concrete beams.

The full-day internship allowed the students to apply and deepen their theoretical knowledge on concrete corrosion and rehabilitation of a listed structure in practice. It gave them the opportunity to gain an insight into the day-to-day work of engineers in the field of structural engineering.

SFB 837 Workshop

On November 02, 2022, the workshop on "Current developments on annular gap mortar in mechanized tunneling" took place within the framework of the Collaborative Research Center 837. At the event, current

The speakers were Dr. Paul Gehwolf (Dr. Spang GmbH), Dipl.-Ing. Maik Weber (Wayss & Freytag), Tilman Schade M. Sc. (PORR GmbH) and Tagir Iskhakov M. Sc. (RUB, Chair of Statics and Dynamics).

In addition, the Institute for Building Materials was represented by both a lecture by Prof. Dr.-Ing. Rolf Breitenbücher entitled "Deformable annular gap mortars for compressive rock" and a lecture by Dr. Bou-Young Youn-Čale on "Test methods for assessing the consolidation potential of annular gap mortars".

reCYCL:ING - TOGETHER FOR MORE GREEN ON THE CAMPUS

The student assistants of the Institute for Building Materials have participated in the project "reCYCL:ING" of the Press and Public Relations Department of the Faculty of Civil and Environmental Engineering. As part of the project, the planters in the immediate vicinity of the I-building row, which are in need of renovation, are being repaired. This concerns not only the planting but also the exterior appearance. For example, both planters refurbished by the Department of Building Materials Technology were clad with a surrounding concrete facing. The concrete used contains polymer fibers that improve durability as well as resistance to weathering. When the contents of the bucket were replaced, large quantities of plastic packaging waste came to light, which led to the idea of setting an example for a more sensible and sustainable use of plastic.
