WebSingle size aggregates make the concrete harsh and does not work well with trowel and between the cables, strands or sheathing. The graded coarse aggregate is defined by its nominal size i.e., 40 mm, 20 mm, 16 mm, 12.5 mm, etc. For example, a graded aggregate of nominal size 12.5 mm means an aggregate most of which passes the 12.5 mm IS Sieve.
