Accumulation of mineral ballast on organic aggregates

The accumulation of “ballast minerals” such as clays, calcium carbonate, and silica on organic aggregates may affect the aggregation, sinking velocity, and flux of POC [Ittekkot, 1993; Armstrong et al., 2002; François et al., 2002; Hamm, 2002; Klaas and Archer, 2002]. Ballast minerals have been postulated to enhance the fraction of surface primary production that reaches the seabed by either

Different Types Of Aggregate And Their Uses

- Ballast is the coarsest form of aggregate available. How is it made? Typically made of crushed stone, although ballast has often consisted of less suitable materials such as burnt clay. Is it for you? If what you need is either concrete mixes, filling gaps in hard core, as a concrete component, pathways, or major footings, then this is for you.
