Nachhaltigkeit durch Re-Use – Ermittlung der rechnerisch notwendigen Mindestfestigkeit von Glas in unterschiedlichen Anwendungszenarien
Bachelor thesis
The construction industry faces the challenge of massively reducing CO₂ emissions. Glass is energy-intensive to manufacture, but theoretically infinitely recyclable or – even better – directly reusable. The problem is that recycled glass can have lower surface strength than new glass due to surface defects, which means it has a reduced load-bearing capacity.
In order to be able to use glass safely in new windows and facades, both the limit state of load-bearing capacity (stress) and the limit state of serviceability (deformation/deflection) must be verified. In certain cases, the limit state of serviceability is decisive.
Core data
Research objective
A systematic investigation will be conducted to determine the extent to which material strength may decrease without the limit state of load-bearing capacity leading to premature failure. Through this reverse calculation, we define performance classes for recycled glass that enable its safe reuse in modern window and façade systems.
