What does fm stand for in a sieve analysis

  • Fineness Modulus - an overview ScienceDirect Topics

    In the early days the Fineness Modulus (FM) was the favored tool for quick evaluation of soils and soil blends. The FM is a number used to describe the mean particle size of a soil sample, e.g. an FM of 2 describes a sandy soil and an FM of 7 is a blend too coarse for rammed earth. It was developed by the US Army Corps of Engineers.

  • Effect of Fineness of Sand on the Cost and Properties of

    A curve has been plotted between FM of sand Vs C/B Ratio as shown in Figure 6. From this graph, it is seen that C/B ratio reduces considerably as the FM of sand increases. From FM varying from 2.0 to 3.0 the C/B ratio reduces by 71%. Thus, it is advisable to use coarser sand in Concrete. Conclusion
