2016/03/07· Fineness modulus gives the idea about how course or fine the sand is. Lower FM indicates fine sand and higher FM indicates courser sand.Fine sand requires more cement paste due to high surface area and tendency to develop
than river sand. The particle shape is cubical, which is almost closer to rounded river sand. Another issue associated with river sand is that of obtaining required grading with a fineness modulus (FM) of 2.4 to 3.1. Generally2.9
Sand generally includes river sand, artificial sand, mountain sand, dilute sand, and lake sand. It can be classified into four grades according to fineness modulus : Coarse sand: fineness modulus of 3.7–3.1, with an average particle diameter of 0.5 mm or more;
2018/04/10· FINENESS MODULUS OF SAND AND SIEVE ANALYSIS OF SAND/HOW TO DECIDE ZONE OF SAND (FINE AGGREGATE).
River sand 2.507 Quarry dust 2.688 Coarse aggregate 2.703 3.2.3 Fineness Modulus Fineness modulus is an empirical factor obtained by adding the cumulative percentages of aggregate retained on each of the standard
2017/12/03· Therefore, fineness modulus of coarse aggregates = sum (cumulative % retained) / 100 = (717/100) = 7.17Fineness modulus of 7.17 means, the average size of particle of given coarse aggregate sample is in between 7 th and 8 th sieves, that is between 10mm to 20mm.
Fineness Modulus of Sand To calculate the fineness modulus of sand, the sum of the cumulative percentages retained on the following sieves are divided by 100: 150μm (No. 100), 300μm (No. 50), 600-μm (No. 30), 1.18mm (No
2018/09/20· 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
