From the gradation curve and size distribution, fineness modulus (FM) of IFS aggregate was found to be 7.19. A blend of fine aggregate (70% Qibla Bandi and 30% of Chenab river sand) having fineness modulus of 2.49 and Specific gravity of 2.68 was introduced in concrete mix design (Table1-B). As per ACI 211.4R-93 [30], a mixture of concrete has ...
Aug 31, 2020· Fineness modulus gives us overall idea of whether a material is finer or coarser; higher the FM, coarser is the material and vice versa. It also indicates the surface area of particles of the aggregate, the required amount of fresh cement paste to cover the aggregate particles will be less and thus less water is required.

Fineness modulus of sand is an index arrived based on the particle size analysis and then dividing the sum of the cumulative percentage of particles retained on the sieves by 100. it is important to note that higher the fineness modulus, higher is the coarser portion of the sand.
Fineness modulus - Wikipedia. The Fineness Modulus (FM) is an empirical figure obtained by adding the total percentage of the sample of an aggregate retained on each of a specified series of sieves, and dividing the sum by 100.
The fineness of a precious metal object (coin, bar, jewelry, etc.) represents the weight of fine metal therein, in proportion to the total weight which includes alloying base metals and any impurities. Alloy metals are added to increase hardness and durability of coins and jewelry, alter colors, decrease the cost per weight, or avoid the cost of high-purity refinement. For example, copper is ...

What is fineness test of cement? The test done for finding the fineness of cement by sieving the cement on the standard IS sieve is called the fineness test of cement. The proportion of cement size greater than 90 microns is considered as fineness cement. In other words, the fineness of the cement is the particle size of cement.
