Since it was published in 1983, the limitation of materials concrete is M25 and Steel Fe500. Now the concrete technology developed a lot and Euro code starts with Concrete M30 to M60 and Steel Fe500 to Fe550. This app includes both Euro standard and Indian standard with Concrete M15 to M60 and Steel Fe250 to Fe550. The usage is very simple just replace the existing values in the app with your real design values and click on Calculate button to get results of your design.
