Fineness Modulus of Fine, Coarse or Combined Aggregates

Reference ASTM C 136M-14

Fineness Modulus (FM) is an index of the fineness of an aggregate. In general, the higher the FM, the coarser the aggregate.

Fineness Modulus - The Fineness Modulus (FM) of fine, coarse, or combined aggregate is calculated by adding the cumulative percentages by mass retained on each of a specified series of sieves and dividing the sum by 100. The specified sieves for determining FM are: 150 μm (No. 100), 300 μm (No. 50), 600 μm (No. 30), 1.18 mm (No. 16), 2.36 mm (No. 8), 4.75 mm (No. 4), 9.5 mm (3⁄8 in.), 19.0 mm (3⁄4 in.), 37.5 mm (11⁄2 in.), 75 mm (3 in.) and, 150 mm (6 in.).

This TransCalc tool can be used to calculate and plot the Fineness Modulus of sample with reference to a selected specification. The input data can also be saved in the form of a pdf report. The plots are interactive and can be zoomed in or out and hovered over for additional data display. The plot can be saved by using the toolbars located on the top right of each plot. Please make use of the help texts provided in each input cell for further guidance on the usage of this tool.
