Aiming at maximizing the recyclability of glass and integrating the sustainability with glass structural application, the concept of recycled glass beam has been proposed at the beginning of this project. Based on the investigation of existing glass manufacturing and recycling industry, the resource material has been targeting at float glass from building sector. This thesis present the recycling process in the lab, as well as the selection of experiment method. In the view of structural application, the mechanical property of the recycled float glass has been tested and the results has been discussed in combination with chemical composition analysis. The prediction of the material property for this recycled float glass, especially the structural behavior has been raised on account of the empirical data and the computational analysis. At last, the applicability of the recycled float glass has been proved, following by the data of relative mechanical properties. This thesis is end up with the discussion of the possibility for further development and the conclusion of this recycled float-glass beam project.
