Concreting on timber balconies?

why not use cement sheet flooring 22mm or thereabouts and pack the joist to get fall towards the front of the deck then attach a gutter to the front, this is the way its usually done.

240 x 45 F17 maximum allowable span = 4.8M. 25% x 4.8M = 1.2M

Yes, I agree with you there :)

I was not thinking of the balconies as being cantilevered, hence my comment...

You WILL of course need to ensure that the other supporting structure will withstand the weight, the "parts" holding/supporting the trusses.

...assuming there was some support at the outer ends of the trusses.

Thanks for your feedback, I think I will check with an engineer.

Thanks for your feedback, I ended up asking an engineer who advised that I did not have a problem with the actual weight of the concrete, but it was a bad idea due to movement and shrinkage of timber.
