under construction - half circle reinforced concrete inside (15cm) thick natural stone outside ,all around - 4meters wide - 2m deep from centre (2m ARC) 2.3meters deep -- 4 viewing windows of 1m x 1m x 12cm tempered (tempershield) windows in individual supported steel frames 10cm x 10cm . Water level will be level with the viewing panes giving a pressure to the panes of 1m water height
Size
4m x half circle ( 4 m depth ) height is about 2.3 meters
Water Conditions
river water flowing out of huge swamp areas with a ph of about 6
thanks for your reply - I have done quit a bit of research and nobody or nowhere can I find info on whether the 1mx1mx12 toughened glass would do or not .If I use your calculating tool with a safety factor of 2 WITH NORMAL glass it would need 13mm so I would assume that as toughened glass is at least 5x stronger that 12mm should be MORE than enough?? I could double that with 2 panes to 24mm . If I put the glass on a flat surface on a black cloth in the sun so it heats up ,clean it properly , put a small continuous bead of silicone around the edges , put the second glass on top , the weight (heavy) should press it down and form a thin airtight seal all around , then when it cools the hot air inside should shrink and cause a vacuum pulling the 2 panes tightly together ? ( in theory) I thought of laminating them together but that cannot be done in the congo ,pity!-Again thanks for your help
