Giving ash a new life. The vast majority of the incinerator bottom ash (IBA) consists of inert brick, rubble, glass, ceramics, and stone. With over 20 years of experience processing and handling IBA aggregates (IBAA), we believe that IBAA deposits can be better used and offer an alternative manufactured aggregate suitable for many applications.
The fines fraction generated by crushing of concrete waste for production of recycled concrete aggregates amounts to 40 - 60 mass-%. Technically, fine recycled concrete aggregates (0 - 2 mm, fRCA) may be employed as a sand substitute in new concrete products. This is, however, hampered by the materials tendency for bridging/caking …
By Mat Herron Properly managing aggregate stockpiles means overcoming challenges both old and new, though drone technology is playing a greater role in solving those problems, experts say. Among the current obstacles faced by aggregate managers, especially those who run smaller plants, is the growing number of mixes being …

Bulk Aggregates Loading and Stowage: Aggregates are loaded onto the vessel using specialized equipment like conveyor belts, clamshell grabs, or bucket wheel loaders to ensure efficient and safe cargo handling. Proper stowage is essential for maintaining the stability of the cargo during the voyage and preventing cargo shifting or …
Aggregates may be broadly classi fied as natural or artificial, both with respect to source and to method of preparation. Natural sands and gravels are the product of weathering and the action of wind or water, while manufactured crushed fine aggregate and crushed stone coarse and fine aggregate are produced by crushing natural stone.
Aggregates, which account for 60 to 75 percent of the total volume of concrete, are divided into two distinct categories--fine and coarse. Fine aggregates generally consist of natural sand or crushed stone with most particles passing through a 3/8-inch sieve. Coarse aggregates are any particles greater than 0.19 inch, but generally range ...
