German House for Research & Innovation Showcases Cutting Edge Innovation & Technology
The German House for Research and Innovation in New Delhi in association with the Consulate General of Federal Republic of Germany and Max Mueller Bhavan, Kolkata, organized the “Excellence on Tour!” Road Show.
Overview of the Event
The event was graced by eminent personalities like the IISER Kolkata Director, Professor Dr. R. N. Mukherjee; the German Consul General, Rainer Schmiedchen; the Vice-President of the German Research Foundation (DFG), Professor Dr. Dorothea Wagner; the Director of the Max Planck Institute for Solar System Research, Professor Dr. Laurent Gizon and the Undersecretary Maximilian Metzger of International Cooperation of the German Ministry of Education and Research (BMBF).
Focusing on cutting-edge research work of the 21st century, the road show was enriched with several informative sessions focusing on latest science, technology, research and innovation strategies. The workshops and lectures will be structured around important themes such as toy technology, cancer biology, isolation of DNA, natural products, translucent concrete, role of antibiotics and many more.
Lecture on Textile Reinforced Concrete, Natural fibre based hybrid composites & translucent concrete:
Textile Reinforced Concrete (TRC) is an innovative composite material made from a concrete matrix and textile reinforcement by either glass or carbon, which makes the production of extremely light and slender components permissible. This flexible reinforcement makes it possible to create free forms and geometries. To create textile reinforced concrete, free-flowing fine-grained concretes are used to ensure a good bonding behavior between textile reinforcement and the surrounding concrete matrix.
RWTH Aachen presented this lecture on “Textile Reinforced Concrete, Natural fibre based hybrid composites, translucent concrete” where they presented innovative structures made of natural fibres, instead of the traditional iron & steel bars. These have a lot of advantages: They are less corrosive and easily moldable in aspects of design and strength. It emits less CO2 and is very eco friendly. It is based on the green structural concept, comprising of precast and less concrete hence it is lighter. Compared to iron and steel, it is thin, material saving and less eroding. Textiles do not corrode, hence chances of cracks formation are also less.
Development of the Idea and its Implementation
IIT, Delhi students collaborated with RWTH Aachen University to formulate this innovative technique. The fundamental research funded by German institutes replaced the iron and steel with glass rods and mono-filaments which granules of LED inserted in them, which emits light at night and possesses impressive moldability. As the network is in 3d format, it exerts load transmission to a larger area and the pressure is shared.
India is a country filled with natural resources, hence its forms a wonderful platform for creating concrete with neutral fibres, mesh, jute, flax, bi-axial warp knitted fabric and so on. It gives better ductibilty than Iron and Steel structures. Two programs in Germany have already adopted this innovative technique, and is soon going to be adopted and implemented in India. This will prove to be hugely beneficial for Indian conditions. Cost of housing, roads will reduce with such an effort.
Uses of textile reinforced materials, concretes are extensively increasing in modern days in combination with material science and textile technology. Bridges, Pillars and Road Guards are prepared by jute reinforced concretes to withstand vibrations and sudden jerks.
Translucent concrete popularly known as light-transmitting concrete, is a concrete based building material with light-transmissive properties due to embedded light optical elements – usually optical fibres. Light is conducted through the stone from one end to the other. This results into a certain light pattern on the other surface, depending on the fiber structure. Shadows cast onto one side appear as silhouettes through the material.
The German company LUCEM produces concrete panels with optical fibers inside. The material combines the compactness of concrete and the ease of light. During daytime, it seems to be an elegant natural stone cladding, but surprises with light coming out of the material during evening. In this way, an elegant, non-technically looking facade becomes a media platform for interactive light display. This new technology was recently showcased on a completed building in Germany: the worldwide first Media Facade made with LUCEM Light Transmitting Concrete.
