RE: coefficient of friction: concrete on concrete
In any case common assumption/specification for cohesionless soil is not to take more than 2/3 of angle of internal friciton of soil at base.
For concrete on concrete it depends on surface status. You can use as guide the values recommended for shear-friction. If plain, coef friction 1 and if rough 1.4, Nilson (old) gives.
Concrete on steel, 0.7, Nilson gave.
I have seen some other values for shear friction in code setup.
