How Are Aggregates Used in Concrete? | A.L. Blair

The fineness of aggregates is measured using the fineness modulus (FM). The FM for fine aggregates should be within the range of 2.3 to 3.1. Aggregates that are too fine will have a high water demand, and will also result in a sticky concrete mix.

70% sand with the remainder being gravel. The fineness modulus of the sand and gravel used varies from region to region. Product densities usually range from 135 pounds to 145 pounds per cubic foot. Admixtures are often used to increase concrete strength

Effects of various fineness moduli of fine aggregate on

Abstract The effects of various fineness moduli (FM) of fine aggregate on the engineering properties of high‐performance concrete (HPC) were studied. Two kinds of coarse aggregates (stiff and soft) and three kinds of fine aggregates (FM=3.24, 2.73 and 2.18) were used.

What is Fineness Modulus of Coarse Aggregates and Its

Coarse aggregate means the aggregate which is retained on 4.75mm sieve when it is sieved through 4.75mm. To find fineness modulus of coarse aggregate we need sieve sizes of 80mm, 40mm, 20mm, 10mm, 4.75mm, 2.36mm, 1.18mm, 0.6mm, 0.3mm and 0


normalweight sand, a wide range of concrete densities may be obtained. Aggregates for structural lightweight concrete usually have a top size of minus 3/4 in. or minus 1/2 in. Most lightweight concretes use a lightweight coarse aggregate 3/4 in. to #4 mesh (1/2 - #8) with ordinary sand, minus #4 mesh (minus 4.8 mm), however other combinations of

How to Assess the Quality of Fine Aggregate at Site?

3.2. Based on Fineness Modulus As per IS 1542: 1992 – clause 5.2, the fineness modulus of sand shall be not less than 1.4 in case of crushed stone sands and crushed gravel sand and not less than 1.5 in case of naturally occurring sands. Lower FM indicates fine sand and higher FM indicates courser sand. 4. Result interpretation 4.1.

Effects of source materials, fineness and curing methods on

The fineness modulus of sand was calculated as 2.41 using sieve analysis following ASTM C136 . The table also indicates that grain size of the raw materials is approximately equivalent to the d 10 , d 50 and d 90 that are used to determine the size of a particle.

The Importance of Fineness Modulus

In 1925, Duff Abrams introduced the concept of fineness modulus (FM) for estimating the proportions of fine and course aggregates in concrete mixtures. The premise: "aggregate of the same fineness modulus will require the same quantity of water to produce a mix of the same consistnecy and give a concrete of the same strength."
