agregaten

Agregaten is a term that can refer to different concepts depending on language and context. In many contexts it is a plural form related to the word aggregate. In English, the standard plural is aggregates, and agregaten is not common, often appearing as a misspelling or a transliteration error.

In geology and materials science, an aggregate is a coherent mass of mineral particles, grains, or crystals. Aggregates may be clumps of crystals bound together by cementing materials, or a loose collection of grains forming a distinct unit within rock or sediment. Natural aggregates include sand, gravel, and crushed stone, which are widely used in construction and road-building. The properties of aggregates—such as grain size distribution, shape, density, strength, and cleanliness—significantly influence the performance of the final material, including concrete.

In engineering and industry, the term also appears in the sense of equipment units. For example, in Dutch and related languages, a generator set is called an aggregaat, with plural aggregaten; multiple units would then be referred to as aggregaten. The spelling agregaten may occur in older texts or nonstandard usage, but aggregates in the English sense are more commonly used for materials, while aggregaat/aggregaten denotes machinery.
