Fine aggregate is made up of particle sizes smaller than (3/16") and extends down to sizes smaller than (#200 mesh). In concrete generally and, to a lesser extent in asphaltic concrete, the proportion of minus #200 mesh sizes is normally limited to just a few percent of the total mass of aggregate....
Constituent Materials of Concrete
Coarse aggregates generally range between 3/8 to 11/2 inches ( mm to mm) in diameter. Most coarse aggregate used in concrete is crushed stone, although smooth river rock is also used. Inadequate amounts of fine aggregates can cause excessive bleeding, difficulties in pumping concrete, and difficulties in achieving smooth troweled ......
