• ### Aggregate in Concrete The Concrete Network

01/03/2011· The dividing line between fine and coarse aggregate is the 3/8-inch sieve. The fineness modulus (FM) is an index of the fineness of an aggregate. The FM is calculated by adding the cumulative percentages by mass retained on each of a specified series of sieves and dividing the sum by 100 (see Table 1). The FM for fine aggregate should fall within the range of 2.3 to 3.1. The FM should not

Only, while packing aggregate should be of equal size, that is of the same grade. Either all of them should be coarse, or all of them should be medium or fine grade. This implies that even if sand alone is packed, voids to the tune of 40-45 percent are again left. This principle of formation of voids is the governing principle for the preparation of concrete under this method. When the
