Fine aggregate Coarse aggregate The fine aggregate is natural sand that has been washed and sieved to remove particles larger than 5 mm, and the coarse aggregate is a gravel that has been crushed, washed and sieved so that the particles vary from 5 to 50 mm in size. The fine and coarse aggregate is delivered separately.
