Scaled structure

Explanation:

A concrete model is a model that is in fact a physical representation of something. The opposite is an abstract model, which is not a physical representation. Theoretical, conceptual, and computer models are all abstract models.

Scaled structure (scale model) is a three-dimensional physical representation of an object that preserves accurate relationships between all of its important aspects.
