Morphology

hydrated + lime

The compound meaning — lime that has had water added or that contains water molecules — is directly and compositionally derived from 'hydrated' (containing water) + 'lime' (the building/agricultural material). Although it's a technical term, the morphological composition is regular and cross-linguistically common, so a B1 learner who knows both constituents would very likely infer the intended meaning.

Etymology

Hydrated lime is named for how it is made: the word hydrated means 'with water' and lime is the basic white material, so people add 'water' to 'quicklime' to make a softer white powder. That's why today hydrated lime means the white, powdery substance used in building, farming, and water treatment.
