NEURODESIGN® · MATERIAL CLASS · STONE AND EARTH
Terrazzo
Aggregate in a cement or resin matrix, ground flat. Pattern is aggregate-driven, statistically uniform at room scale and highly varied at hand scale.
Decisive attributes
The attributes that most determine how this class behaves and how it is experienced. No values are shown, because a value belongs to a product and not to a class. Two products of the same material can differ from each other by more than the material differs from its neighbours.
Typical application
Flooring. Vanities. Lobbies.
Worth watching
Cement-matrix and resin-matrix terrazzo are usually specified interchangeably despite entirely different binder chemistry and emissions behaviour.
Evidence
No record in the research corpus tests human response to this material class. Its physical behaviour may be well understood and its properties may be entirely predictable from the attributes above. That is a different thing from evidence that a person responds to it, and this library does not convert one into the other. The absence is shown rather than filled.
Outcomes it could bear on
Outcomes whose material levers overlap this class. This is a structural relationship in the ontology, not a finding: it says the property is relevant to the outcome, not that this material produces it.
