Zwanzig20 – C3 – Sub project V3.5 „Investigation of success factors for knowledge transfer, scaling potential and structural change of innovative technologies taking example of carbon reinforced concrete”

Univ.-Prof. Dr.-Ing. Dipl.-Wirt.-Ing. Jens OTTO, Dipl.-Ing. Jan KORTMANN

The research project C3-V3.5 will develop concepts for the transfer of innovative technologies and products to be marketable. In order to reach that goal, the current obstacles and weak points are to be identified and the requirements of the players in the market (e. g. engineers, architects, construction companies, building owners) have to be pointed out. For the construction material carbon fibre reinforced concrete the gaps within the knowledge transfer have to be found and compared to the requirements of the market. Therefore expert interviews will be carried out within the project. Furthermore current methods of knowledge transfer will be evaluated, refined and transferred to carbon reinforced concrete. To transfer laboratory scale applications into large scale usage, scaling potentials will be explored and evaluated on examples. In close contact with other C3 partners a concept for innovation management and knowledge transfer of innovative technologies and construction materials will be developed at the Institute for Construction Management.

Basic evaluation for adaptation of an innovative demolition method from the mining as a new technology for the selective dismantling in sensible areas - EIV - Bau

A large part of today’s construction projects are realised in the redevelopment of buildings. In the most cases this requires a large-scales and sensitive dismantling of existing constructions. Dismantling technologies in inner-city housing areas effort particularly high demands need to be fulfilled by the dismantling technologies in inner-city housing areas and ongoing use of buildings. The high demands also need to be fulfilled by the selective dismantling of new building project in case of construction defects and concreting mistakes. The reasons are located in higher-strength of concrete and the protection worthiness of existing building structures. The currently used dismantling technologies don´t satisfy the growing demands in the building practice. Depending on the method dismantling is characterised by a high emission, like vibrations and noises, a great amount of blasting abrasive, slow performance progress or a high physical involvement. The electrodynamic Elektro-Impuls-Verfahren (EIV) is an alternative technology. This newly developed process technology for the implementation in mining and special foundation engineering is based on destruction of solid material through high-voltage pulses. On the bases of large-scale experiments in mining it was able to show the high dismantling performance in combination of a low energy consumption. It is proved that the technology has a very low-emission and selective. The amount of cost savings are up to 30 % in comparison to conventional methods. The aim of the research project is to define the basics for a transferability of the electrodynamic Elektro-Impuls-Verfahren (EIV) on the low-emission and selective material removal in building constructions, civil engineering and structural engineering.

F20-17-1-067 – Adaptive building Structures to increase the resource efficiency of storied buildings in the inner-city area

Univ.-Prof. Dr.-Ing. Dipl.-Wirt.-Ing. Jens OTTO, Dipl.-Ing. Anne HARZDORF

Within the research project of the research initiative ZukunftBau supported by the Federal Ministry of the Interior, Building and Community the goal is to develop a system for the valuation of adaptive building structures. The valuation depends on functional, constructive, ecological and economical influence factors. Two targets of the project are the reduction of the resource consumption and the long-term value preservation of buildings.
The basis of the investigation is an extensive analysis about inner-city multi-story buildings. In combination with the fundamentals the relevance of different types of use, depending on the site conditions will be examined and translated into potential future scenarios. This first part of the investigation is necessary for the next step, where the functional, constructive, ecological and economical requirements of selected types of usage will be defined, combined in building parameters and integrated in the assessment system. Another task is the elaboration of organizational and legal framework conditions for the planning and execution of buildings. Furthermore a goal is to develop different proposals for the integration of the assessment system into the practice. Overall, strategies for the design and practical realization of adaptive buildings are to be developed through systematic structuring of multi-story buildings.

Zwanzig20 – C3 – Sub project V3.2 „Physical and morphologic characterization of dusts of the processing of carbon fibre reinforced concrete”

Univ.-Prof. Dr.-Ing. Peter JEHLE, Dipl.-Ing. Jan KORTMANN, Dipl.-Ing. Florian KOPF

Within the previous project C3-V1.3 the physical and morphological characterization of dust, which originates in the processing of carbon fibre reinforced concrete, was carried out. Dust within critical (health hazardous) dimensions has not been found within the experiments. However it was observed, that thermal stress causes a change in the structure of carbon fibres. It is therefore necessary to examine the dust from processing carbon fibre reinforced concrete after a thermal load. The project C3-V3.2 will test this behavior with dedicated experiments. It will not only contain a geometric analysis of the dust particles, but also an experiment with lung cells, which will be loaded with the dust particles. Due to the constant development of carbon reinforced concrete, new combinations of reinforcement material and concrete will be tested. This will also validate the results from the previous project.
The Institute for Construction Management is responsible for providing construction relevant data to aide with the evaluation of the experimental data. Furthermore it will help to translate the results into instructions for handling the construction material.
