Prestressed Basalt Reinforced Graded Concrete Components

Research Project 22-1 (RP 22-1)

IntCDC Research Project 22-1 – Prestressed Graded Concrete Components with Basalt Reinforcement
DESIGN, HANDLING AND FABRICATION OF PRESTRESSED GRADED CONCRETE COMPONENTS WITH BASALT REINFORCEMENT

This research project focuses on the first steps towards the integration of prestressed basalt fibre reinforcement into 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 achieve their performance with a minimum amount of material will be developed, by synthesising 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 focus to achieve maximum mass savings and recyclability. To this end, a prototypical manufacturing process for mineral sheathings will be established. 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 experimentally validated.

The project will be carried out in close collaboration with the Functionally Graded Concrete Building System (RP 1-2), the on-site Cyber-Physical Construction Platforms (RP 8-2 and RP 16-2) and the Holistic Quality Model (RP 18-2).
