column size- 200x200 mm assume concrete cover is 40 mm and 8 dia bar using so that, ties size will be 120x120 mm [(AxE mm)] using formula- 2x(A+E)+24 dia of bar = 2x(120+120)+24x8=672 mm.
200mm
50 mm dia gi pipe 4mm thick
hi, as a rule of thumb, approximately 60 bricks per sq metre , (60x16.5) about a thousand should do it.
Block work - 200mm Thick sqm1:30.26 sqm1:40.21 sqm1:50.16 sqm1:60.12
600,000mm
200mm = 20cm
20cm=200mm
25cm is longer than 200mm which equals 20cm
It can be used, provided you know the maximum weight on vehicles on it. From experience, 30 ton trailers can run comfortably on a 200mm thick g-25 concrete mix..
the formula for piers is: Pi x the raduis squared x the depth Ie a 400 mm diameter pier 1.2 metres deep would be: 3.14 x .2 (200mm)x .2(200mm) x 1.20(1200mm) = .150 cubic metres
