احصل على السعرAggregates are inert granular materials such as sand, gravel, or crushed stone. 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 inch, but generally range between 3/8 and inches in diameter.
