Apr 17, 2015· 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 crack.
Jun 11, 2021· Fine sand: Fineness modulus should lie in between 2.2 to 2.6 Medium sand: Fineness modulus should lie in between 2.6 to 2.9 Coarse sand: Fineness modulus should lie in between 2.9 to 3.2. Sand having a fineness modulus more than 3.2 is unsuitable for making satisfactory concrete. The coarse aggregates have fineness modulus usually more than 5.
Jun 05, 2020· The Formula for Density of Sand: The ratio of the mass of the sand to the volume of the calibrating container gives the sand density. Density = Mass of Sand / Volume of Sand. Let's say that .015 m 3 is the volume of sand and 24 kg is the mass of sand then, 24 / .015 = 1600 kg/m 3. There are the following mean densities of the different ...
If fineness modulus of sand is 2.5, it is graded as very fine sand fine sand medium sand coarse sand
Aug 31, 2020· Surface Area ∝ 1/(Fineness Modulus) Larger value of FM is preferred for fine aggregates. For a good fine aggregate, the FM should be between 2.3 and 3.1 (ASTM Range for fine aggregates). A FM of 4 can be interpreted to means that the fourth sieve from bottom i.e. sieve No. 16 is the average size of the aggregate particles in the given sample.

Fineness Modulus of Sand. Fineness modulus of aggregate is an index number which gives an idea about the finance of aggregate and is an approximate proportion of the average size of particle in the aggregate. It is found out by sieve analysis test of standard size in the laboratory. The thumb rule is lower the fineness modulus, particles are ...
fineness modulus of sand and sieve analysis of sand/how to decide zone of sand (fine aggregate).
Jan 01, 1996· A small number indicates a fine grading, and a large number indicates a coarser material. The fineness modulus of the fine aggregate is required for mix proportioning, since sand gradation has the largest effect on concrete workability. Concrete made with a fine sand (low fineness modulus) has much higher paste requirements for good workability.

Fine aggregate (sand) grading affects consistence and finishability. Fineness Modulus (FM) is an empirical calculation used to support the optimisation of a concrete mix design. It is used to determine 'degree of uniformity of the grading'. This can create a relationship between grading and consistence and/or the amount of cement or water ...
Figure 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.
Fineness modulus of sand is defined as the cumulative amounts of aggregate that remained on each of the sieve sizes ranging from 75 mm to 150 microns are added together and divided by 100. The fineness modulus is commonly used to determine the coarseness or fineness of an aggregate. A higher fineness modulus value suggests a coarser aggregate ...
