represents a coarser material and a lower fineness modulus represents a finer material. Knowing the fineness modulus of aggregate gives you some indication of the amount of paste needed to make concrete using the aggregate. For instance, sand with a low fineness modulus has more voids in it and more particle surface, thus, more paste is

the concept of fineness modulus (FM) for estimating the propor-tions of fine and coarse aggregates in c o n c r ete mixtures. The pre m i s e : "aggregate of the same fineness mod-ulus will require the same quantity of water to produce a mix of the same consistency and give a concrete of the same strength." Over the years, many
Fineness Modulus of Fine Aggregate. Fine aggregates is the sand used in mortars. The size of the fine aggregate is limited to maximum 4.75mm beyond which it is known as coarse aggregates. Fineness modulus is only a numerical index of fineness that gives some idea about the mean size of the articles in the entire body of concrete.
Sep 01, 2014· Fineness 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.
Fineness modulus of fine aggregate is 2.75. It means the average value of a and 3 sieve. It means the average aggregate size is in between 0.3mm to 0 Values of Fineness Modulus of Sand Fineness modulus of fine aggregate varies from 2.0 to 3.5mm.
Aug 31, 2020· Calculate the Fineness modulus of aggregates with the help of following formula. FM = ∑ [(Cumulative % retained on standard sieve of 150μm or above)] /100. Following points should be kept in mind while calculating the FM. Only add the sieves of 150µm and above. If any standard sieve is missing, use the value of next higher sieve.
It is obtained when Fineness Modulus is about 2.7. The net cost of Concrete reduces when FM of sand increases. It reduces by about 6.5% for an increase of FM from 2.0 to 3.0. As the fineness modulus of Sand increases, the Cost/Benefit Ratio reduce by a very large factor. This …
Feb 08, 2019· 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.
