element type for concrete axialsymmetric model

[valval]

Hi all!
I've a problem choosing the element type for my model.
I've to model a concrete block and I want to do that taking advantage of the axialsymmetry of the problem.
So I've to use an element type that has this option.
Up to now I've tried using different element types from the element library (like plane42, plane25, solid273) but I'have not found good results and I think that the problem is that I can't model concrete behaviour in 2d. Is that right?
Is there any possibility to model concrete in 2d with axialsimmetry?
Thanks a lot

i think that solid65 is the best element for modeling concrete , but it is 3-D element
and you must model concrete behavior in a right way.
for symmetry , you can do that by using constrains.
