Maximum length of cantilever beam is 1.2 metres from fixed end.

1) The span to depth ratio for a cantilever of the beam should not exceed 7.
2) Also, the maximum size of cantilever provided should be 10m.
3) i.e length of the cantilever should not be more than 10 meters.

C.R.R.I only works on road and road materials. So, I don't think C.R.R.I has provided any kind of relationship between the strength of concrete and water-cement ratio. Atleast i haven't found anything like this on the internet.
