The present abZ is to be understood as initial development and start-up technology. Their approval is the result of several years of a one-time joint effort of the TUDALIT members. We hope that the planner portfolio will help you in deciding on suitable projects on bending strength of reinforced concrete for the application of this new and fascinating technology. Your tips and suggestions for improvement of the planner portfolio are welcome. Ulrich Assmann Chairman of the Management Board of TUDALIT e.V. as on: 15.

TUDALIT® – the quality brand for textile reinforcements in concrete building The composite textile-reinforced concrete revolutionizes the construction work in the world and opens up new possibilities for builders and architects. The composite textile-reinforced concrete is developed at renowned German research institutions and is available for practical applications. Its areas of application include: q New construction, q Renovation, q Reinforcement. With the quality brand TUDALIT® products are available with the highest technical standards and a close co- operation between manufacturers and companies is guaranteed from planning up to the usage on the building site. The association of the quality brand TUDALIT® was established in January 2009. TUDALIT e.V. has developed and funded the basis for the first general building supervisory approval for more than four years. Valuable experiences have been acquired through a series of projects with approvals in case-by-case basis. as on: 15.

If a reinforcement measure is to be carried out as a quality-assured application by TUDALIT®, the TUDALIT association supports you as a partner. We support you in fulfilling the following conditions laid down in the general building supervisory approval and in proving to the builder: q Use of the TUDALIT®-Kit components defined in the general building supervisory approval Z-31.10-182 q Execution of the work by certified companies, The planner portfolio, section 1 1-2 Build lighter – Shape the future Leichter bauen – Zukunft formen Contact person TUDALIT e.V.

Textile concrete at a glance Textile concrete is a composite material made of special fine concrete matrices and reinforcements of lat- ticed textile layer. The base layer consists of carbon fibers or other suitable high-performance fibers such as alkali-resistant glass fibers. The maximum grain size of the mineral matrix is generally between 1 to 4 mm. The textile carbon reinforcements do not corrode. Hence, for textile concrete with carbon reinforcement, in contrast to reinforced concrete, thick concrete covers are not required. The minimum concrete covers in the textile concrete must only ensure the bond of textile reinforcement and the concrete matrix and must be the reinforcement diameters in the millimeter range.

Typical thickness range of structural component lies between10 mm to 50 mm. According to the present general building inspectorate and approval, based on the number of reinforce- ment layers (up to a maximum of 4), a layer thickness of approx. 6 mm to 30 mm is required while rein- forcing steel concrete components. q The low space requirement of the textile reinforcements makes the material ideal for the restoration and reinforcement of monument-protected structure and for geometrically restricted conditions in existing buildings. q Another advantage of building and restoring the stand with textile concrete is the significantly lower addi- tional loads (dead load of the reinforcing layer). q The plasticity
