Grain Fineness sand test: The grain fineness test method is to find the size of the silica sand particles. It fine grain sand associate with good surface finish & strength of mold will high and lower permeability. It carried out on dry silica sand weight of 50 gms and free from the clay. When the top sieves of mechanical shaker, the sand is ...

Determination of fineness modulus of fine aggregate - Blogger

Jan 13, 2018· Many a time, fine aggregates are designated as coarse sand, medium sand and fine sand. These classifications do not give any precise meaning. What the supplier terms as fine sand may be really medium or even coarse sand. To avoid this ambiguity fineness modulus could be used as a yard stick to indicate the fineness of sand.

Fineness Modulus - site.iugaza.edu.ps

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 sieve is added and

Fineness Modulus - an overview | ScienceDirect Topics

Special fine sand: fineness modulus of 1.5–0.7, with an average particle diameter of 0.25 mm or less. The larger the fineness modulus is, the coarser the sand will be. The appropriate range of fineness modulus of the sand aggregate used in normal concrete is 3.7–1.6. Both medium sand and coarse sand spiked with some fine sand (coarse:fine ...

Sieve Analysis of Soil; Its Determination, Theory ...

Fineness Modulus: Fineness modulus is a single factor computed from the sieve analysis and is defined as the sum of the cumulative percentages retained on the sieve of the standard series divided by 100. The fineness modulus can be looked upon as a weighted average size or a sieve on which the material is retained, and the sieves being counted ...
