Construction aggregate - Wikipedia

Construction aggregate, or simply aggregate, is a broad category of coarse- to medium-grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates.

Protein aggregation - Wikipedia

Protein aggregation. Misfolded proteins can form protein aggregates or amyloid fibrils, get degraded, or refold back to its native structure. In molecular biology, protein aggregation is a phenomenon in which intrinsically-disordered or mis-folded proteins aggregate (i.e., accumulate and clump together) either intra- or extracellularly.

Aggregate. Sand, gravel and crushed stone are all considered to be aggregates. More simply, aggregates include grains or fragments of rock. They are a non-renewable resource which we benefit from daily, but rarely think about. The aggregate industry is Ontario’s largest natural resource industry, affecting almost every aspect of our daily lives.
