Recycled plastic can be used as coarse aggregate in concrete. However, it is important to underline that re using of wastes is not yet economically advantageous, due to the high costs of transport and its effect on the al costs tot of production. Moreover, it is important not to neglect other costs, directly referable to the
Dec 21, 2005 · Gravel coarse aggregate costs about 5 mils per pound, and sand fine aggregate costs about 4 mils per pound. So, the cost of an airentrained 6bag (564 lb) mix made using gravel coarse aggregate (1800 lb) and sand fine aggregate (1250 lb), as we previously mentioned, is about $75 per cubic yard even including the patriotic fly ash or ground
Construction aggregate, or simply "aggregate" is a broad egory 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.

Physical and mechanical characteristics of recycled concrete aggregate (RCA) acquired from concrete waste are thoroughly examined. Though the RCA exhibited relatively lesser performance compared with the natural coarse aggregate (NCA), it reveals the same properties as of normalweight aggregates in several instances.
Unit Weight of Aggregate in Bulk The DryRodded Unit Weight of an aggregate is the weight required to fill a contained or a specified unit volume, after it has been rodded to attain maximum packing. ASTM C29 gives the common methods of determining the DryRodded Unit Weight that is also sometimes called the "bulk unit weight of aggregates
