By not using rebar, the Romans were limited to using their concrete for applications in which it was always under compression, not tension.
Makes a helluva a difference.
Even with rebar in it, I note the offset supports under the West Dodge Expressway in Omaha around the 114th street intersection are already showing tension cracks* and the structure is only ~ 10 years old now.
*not a structural concern, but it does highlight the enormous load on those offset columns, the dead weight of the structure on the backside of those columns does not exceed (by quite a bit) the tension load the column is bearing.

The granting of a pardon is an imputation of guilt, and the acceptance a confession of it.
