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. Aggregates are the most mined materials in the world.
MNR is an example of a reactor where the core is visible while the reactor is operating. The core itself appears to be glowing blue when looked at from the surface, as a result of the Cherenkov radiation. MNR is the only research reactor in Canada with a full containment structure.
There are thousands of aggregate-producing companies in the US, operating in each of the 50 states, and employing 105,000 people. Most aggregate is used by the construction industry, where it is an essential raw material and the main ingredient in concrete and asphalt concrete. [1] [2]

Crushed stone or angular rock is a form of construction aggregate, typically produced by mining a suitable rock deposit and breaking the removed rock down to the desired size using crushers. It is distinct from naturally occurring gravel , which is produced by natural processes of weathering and erosion and typically has a more rounded shape.
Particle aggregation. Particle agglomeration refers to the formation of assemblages in a suspension and represents a mechanism leading to the functional destabilization of colloidal systems. During this process, particles dispersed in the liquid phase stick to each other, and spontaneously form irregular particle assemblages, flocs, or ...

A J-aggregate is a type of dye with an absorption band that shifts to a longer wavelength (bathochromic shift) of increasing sharpness (higher absorption coefficient) when it aggregates under the influence of a solvent or additive or concentration as a result of supramolecular self-organisation.
