Outline of Final Research Achievements |
This study focused on a solar module glass which is one of residues produced by recovery of rare metals. A main component of the solar module glass contains amorphous silica. Therefore, this study evaluated the compressive strength, which is the most important property of concrete, when using crushed solar module glass as a mineral admixture. As a result, it was confirmed that the compressive strength can be secured in case of mixing the crushed glass up to 5% of replacement ratio to cement. However, the compressive strength decreases when mixing the crushed glass of 10% of replacement ratio to cement.
