Tested and approved – TRC on its way to broad application
Indoor reinforcement with TUDALIT®-TRC
The lack of general technical building inspection and design regulations has been an obstacle for the widespread use of textile reinforced concrete (TRC). Despite its easy application, the corrosion resistance of the textile reinforcement, and the high increase in the load bearing capacity of TRC-strengthened structural elements, the use of TRC was only possible after applying for an approval for its application in individual cases (ZiE).
In 2009, pioneer work to draft such regulations began at the Deutsche Zentrum Textilbeton (DZT). A procedure for strengthening steel reinforced concrete with TUDALIT®-TRC was developed and was coordinated with the German Institute for Building Technology (DIBt). After the testing plan had been approved, our institute was commissioned to carry out and to evaluate the many tests required for approval. The small-scaled tests and large-scale tests on building components, aimed at verifying the load bearing capacity, began in 2010, and they were successfully completed with an expert’s opinion in 2014.
With the granting and approval of regulation Z-31.10-182 in June 2014, the scene has been set for a broad and easy use of TUDALIT®-TRC. TRC can now be used as a reinforcement method for indoor reinforced concrete elements. The approval of these technical regulations has increased the acceptance of TRC among contractors, architects, structural engineers and construction companies.
Now, new fields of application need to be opened up and extended through further research and standardisation of TRC. For example, outdoor building elements as well as elements under predominantly non static loading need further examination. There is still a lot of work to do. Let’s get to it!
