DESIGN, HANDLING AND FABRICATION OF PRESTRESSED GRADED CONCRETE COMPONENTS WITH BASALT REINFORCEMENT

This research project focuses on the first steps towards integration of prestressed basalt fibre reinforcement in the graded concrete technology, in order to enable the fabrication of purely mineral components with an improved recycling rate.

Methods for the Co-Design and production of prestressed concrete structures that fulfil their performance with a minimum amount of material will be developed, by synthesizing knowledge in the fields of structural engineering, materials science and production processes. The design of such components includes a parametric-optimisation step. An unbonded post-prestressing of the basalt fibre reinforcement will be a focal point to achieve utmost mass savings and recyclability. For this purpose, a prototypical manufacturing process will be established for mineral sheathings. Moreover, the automation of the critical handling process of the insert elements, hollow bodies for gradation and sheathings for reinforcement will be addressed, especially for complex On-Site environments. Finally, this handling process will be validated on experiments.

The project will be conducted in tight cooperation with RP 1-2, the on-site cyber-physical construction platforms (RPs 8-2 and 16-2) and the holistic quality model (RP 18-2).
