Fine Aggregate and Fineness Modulus. Posted: 2016-10-14 In civil engineering, aggregates with a particle size greater than 5 mm are coarse aggregates, also known as stone; aggregates with a particle size of less than 5 mm are fine aggregates, also known as sand.Qualified fine aggregate should have a good gradation, including fineness modulus, firmness, mud Get price >>
Nov 30, 2020The specifications divide the sand in Zone I to Zone IV. Zone I–(Coarse to fine sand) Zone I to III are suggested for the Concrete works. Fineness Modulus of sand is a number which represents the mean size of the particles in sand. It is calculated by performing sieve analysis with standard sieves (4.75 mm to 150 micron). Get price >>
The sieve analysis, commonly known as the gradation test, is a basic essential test for all aggregate technicians. The sieve analysis determines the gradation (the distribution of aggregate particles, by size, within a given sample) in order to determine compliance with design, production control requirements, and verification specifications.

10/06/2020 Fineness modulus of manufactured-sand concrete influences the properties of concrete such as workability, packing density, voids content, and strength (Goltermann et al., 1997). If the manufactured sand is too coarse it will produce bleeding, segregation and harshness, while if the sand is too fine, it will increase the demand for Get price >>
May 24, 2020What is Fineness Modulus ?? Fineness modulus are ready index of coarseness or fineness of the material. It is also defined as an empirical factor obtained by adding the cumulative percentage of aggregate retained on each of the standard sieves ranging from 80mm to 150micron and dividing the sum by an arbitrary number 100.
