| Summary: | Since the sustainability of concrete became a very important property in the past decades, 15 mixes of self-compacting concrete (SCC), as well as control mixes, were examined to find out the effect of replacing natural aggregates with recycled blue glass (RBG) waste on the rheological properties and permeability of self-compacting concrete. For this purpose, 3 series of SCCs were mixed: the 1st group replaced the natural aggregate (NFA) with fine recycled waste blue glass (RFWBG), the 2nd group replaced the natural coarse aggregate (NCA) with coarse recycled waste blue glass (RCWBG), and the last group replaced the natural aggregate with recycled blue glass (RGA). Each group contains 5 ratios of replacement (0%, 20%, 40%, 60%, 80%, and 100%). The results showed that the torque increased with the increase in recycled green glass replacement; for instance, it increased from 0.95 for control mixes to 1.302, 1.384, and 1.459 Nm for 100% replacement in the 1st, 2nd, and 3rd groups. Meanwhile, the permeability tests include chloride ion permeability (RCPT), a water sorptivity test, and a gas permeability test at 28 days; likewise, this study showed that these characteristics increase with the increase of recycled blue glass. |
