Uses of Aggregates Aggregate can be used in a number of ways in construction. In roads and railway ballast the aggregates are used to resist the overall (static as well as dynamic) load, to distribute the load properly to the supporting ground and to drain the water off the surface.
Soil aggregates, as noted in the section on soil structure in Chapter 1, play a central role in protecting pools of carbon and nitrogen, and are derived from a variety of sources.A mechanism particularly prevalent in many tropical soils is the physical aggregation process, which occurs abiotically as a physicochemical process (Oades and Waters, 1991).
In the Fine Aggregates, the grain-size lies between 4.75 mm and 0.15 mm. In other words, these pass-through from sieve with the mesh size of 4.75 mm and are retained on a sieve of 0.15 mesh size. Sand is the most universally available natural Fine Aggregate.
