Gradation Test | Sieve Analysis of Fine and Coarse Aggregates

So the degree of gradation will decide about the sand to be used. Degree of gradation is also called fineness modulus of sand. We find fineness modulus and compare it the standard recommended values. Apparatus: The apparatus consists of six different types of sieves i.e. #4, #8, #16, #30, #50, and #100 sieve.

WHAT IS THE IMPORTANCE OF AGGREGATE GRADATION IN

Also aggregate comprises 85% of the volume of concrete. So we can definitely say that, most of the requirement of concrete in its plastic state is affected by aggregate properties and, "gradation of aggregate" is one of them.

Sieve analysis - Wikipedia

For each aggregate used in the mix design, include a gradation analysis that is representative of the aggregate. The gradations should be current and are typically the average of more than one individual test for each aggregate. The following chart shows example individual aggregate gradations and combined aggregate gradation

Gradation of aggregates In order to perform the test, a sufficient sample of the aggregate must be obtained from the source. Some PCC mix designs use gap graded aggregate to provide a more economical mix since less sand can be used for a given workability.

The NSA gradation is noticeably finer (greater percentages passing each sieve). The fine materials, composed of angular particles, are rock fines, as opposed to silts and clays in natural sand, and contribute to concrete workability. The various gradations provide standard sizes for aggregate production and quality-control testing.
