بیشترFineness modulus is generally used to get an idea of how coarse or fine the aggregate is. More fineness modulus value indicates that the aggregate is coarser and small value of fineness modulus indicates that the aggregate is finer. Fineness modulus of different type of sand is as per given below. Type of Sand. Fineness Modulus Range. Fine Sand.

بیشترFigure 1 In general, FM defines how fine or coarse the sand is. A small number indicates fine sand; a large number indicates coarse sand. For mix proportioning, fine sand would require more cement and a greater tendency to develop cracks. A coarse sand will produce a concrete mixture that is harsh and difficult to finish and will cause segregation.

بیشترJul 31, 2016· Fineness modulus of sand (fine aggregate) is an index number which represents the mean size of the particles in sand. It is calculated by performing sieve analysis with standard sieves. The cumulative percentage retained on each sieve is added and subtracted by 100 gives the value of fineness modulus.
