Aggregates for Concrete - Civil Engineering

Aggregates for Concrete bination of gravels or crushed stone with particles predominantly larger than 5 mm (0.2 in.) and generally between 9.5 mm and 37.5 mm (3⁄ 8 in. and 11⁄ 2 in.). Some natural aggregate deposits, called pit-run gravel, consist of gravel and sand that can be readily used in concrete after minimal processing. Natural gravel and sand are usually dug or dredged from a pit ...

Material Definitions | Steed and Evans Limited

Fineness Modulus An empirical factor used to measure the fineness (or coarseness) of fine aggregate. The fineness modulus is defined by both CSA and ASTM. A low number indicates a fine sand, a high number a coarse sand. For supply of concrete fine aggregate, it has been found that a Fineness Modulus of between 2.3 and 3.1 will normally give satisfactory workability. It is good practice to keep ...

What is Fineness Modulus of Sand (Fine Aggregate) and ...

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 subtracted by 100 gives the value of fineness modulus.

Filler effect of fine particle sand on the compressive ...

The results show that the compressive strength of mortar contributed from the filler effect of smaller particles is higher than that of the coarser ones. The difference in compressive strength of mortar tends to be greater as the difference in ground river sand fineness increases. The results also suggest that ASTM C618 specification is not practically suitable for specifying pozzolan in ...

fineness modulus of the sample may require a concrete mix redesign. Applying the 0.20 Applying the 0.20 variation does not permit the fineness modulus to be less than 2.50 or morethan 3.10.

Stucco Sand and ASTM C 897 in Florida - Titan America

of the sand particles (see Table below) and the Fineness Modulus (FM). This is the area that creates most of the confusion. There are few, if any, naturally occurring sands in Florida that will meet the gradation requirements of the standard. Of course, natural sand can be modified with the addition of the required gradations of particles; but, this process is extremely costly and time ...

Calculating your grain fineness number. – Worldstar ...

The AFS Grain Fineness Number (AFS-GFN) is one means of measuring the grain fineness of a sand system. GFN is a measure of the average size of the particles (or grains) in a sand sample. AFS-GFN gives the metalcasting facility a means to verify its molding sand is staying within specification for the castings being produced and avoid conditions that could lead to potential casting problems.
