How would you create a concrete ramp (angle 1:12)?
Wouldn't gravity be against you?
Pouring concrete tomorrow

    you use a relatively dry mix of concrete, compared to what you'd use for a horizontal slab so it doesn't run downhill before its set enough to stop moving

    Ask for 25mm slump and work the concrete from the lowest end to the highest

    Make sure you have the shuttering in at the right angle too as well as all said above. If you are walking or driving on it you want a textured/ribbed finish ideally.

    And it's a reasonable enough question !  But the answer is basically, as has already been mentioned, you use a fairly dry mix.
    If you Google for "Concrete Slump" you'll find plenty of fascinating articles on the technicalities of it all.  But any professional builder will be well aware of the correct mix to be using - with concrete, you usually vary both the mix (ratio of the ingredients) and the consistency to suit the particular application you're using it for.

    They have a steel cross frame in place on the screed (for the ramp (which includes a "hairpin bend")
    Total length 26 feet 
    Concrete coming in the morning 
    No sign of any rebar mesh yet though

    Not sure this is relevant but we had a metal ramp fitted to access the front door. ( paid for by social services).
    When the installers arrived there was a lot of discussion about guard rails. I will not go into detail but there are H&S rules about ramps and safety rails so just wondering if these will be part of your installation?

    Thanks 
    Only as far as the fact that we are getting rails fitted
