Concrete Aggregate . Concrete aggregate is made up of fine and coarse aggregates. Fine aggregates are natural sand or crushed stone where most particles are smaller than 5 mm. Coarse aggregates are a combination of gravels or crushed aggregate with particles mostly larger than 5mm, and generally between 10 mm and 40 mm.
