    How dry does the soil have to be for lime cement, used in a greenhouse foundation, to be allowed to set ?

    Mortars need water and moisture to crystallize in order to set. Add some ash for it to set like concrete.

    Wood ash is quite moisture retentive due to the microscopic holes formed during combustion .. that little fact sprung from my memory when you mentioned it. Thanks

    So I mixed lime and sand. No wood ash as I wasn't able to find any.
    The mix was quite runny going in, I definitely added more sand than lime.
    I was told the lime needed to sit in water for a few days so that's what I did.
    24hours later and the cement is still soft to the touch.
    Does the lime need longer to set or do I need to start again ?
