Overview. The gradation and size test (Figure 1) is used to determine aggregate particle size distribution. Size distribution is perhaps the single most important aggregate quality associated with the control of HMA mixtures.
Classification of aggregates based on shape and size such as coarse and fine aggregates are discussed here, What is an Aggregate? Aggregates are the important constituents of the concrete which give body to the concrete and also reduce shrinkage.
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.
Fineness modulus of coarse aggregates represents the average size of the particles in the coarse aggregate by an index number. It is calculated by performing sieve analysis with standard sieves. It is calculated by performing sieve analysis with standard sieves.
Because of this, gradation is a primary concern in HMA and PCC mix design and thus most agencies specify allowable aggregate gradations for both. Maximum Aggregate Size Maximum aggregate size can affect HMA, PCC and base /subbase courses in several ways.
The gradation of the coarse aggregates used in concrete pavement and concrete base shall meet the requirements for 37.5 mm and 19 mm aggregate shown in Table 4. Aggregates shall be stockpiled as
Different volume ratios of coarse (aggregate size numbers 467, 57, or 67), intermediate (aggregate size number 8 or 89), and fine aggregates were selected to

of coarse aggregates (quartzite, limestone and granite) were selected for blending and optimization with medium sand (FM = 2.84) in different proportions to satisfy the target gradation. After optimizing the aggregate gradation the cement content in the concrete mix

Importance: This experiment is carried out to find and check the gradation of coarse aggregate i.e. crush. The concrete's main bulky material is crush, it is used to increase the volume of the concrete along with its strength giving property.
Gradations in Aggregate - The Concrete Network. Broad coarse-aggregate gradation ranges are listed in Table 2 of ASTM C 33. These broad gradation bands are for use all across the country.
Importance: This experiment is carried out to find and check the gradation of the fine aggregate i.e. sand. The concrete consists of three basic solid materials, one is the sand whose fineness is checked by experiment no 1, the other two materials are the coarse aggregate that is the crush while the third is the fine aggregate that is the sand.

A sieve analysis (or gradation test) is a practice or procedure used (commonly used in civil engineering) to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by ...

The grading of coarse aggregate may be varied through wider limits than that of fine aggregates, since it does not affect the workability, uniformity and finishing qualities of concrete mix. As per IS-383 the grading limit of coarse aggregate, both for single size as …
Coarse aggregates used in concrete making contain aggregates of various sizes. This particle size distribution of the coarse aggregates is termed as "Gradation". The sieve analysis is conducted to determine this particle size distribution.
Second, is you have to determine the gradation or the distribution of aggregate particles by size, within a given sample in order to determine the concrete production requirements and …
Sieve analysis helps to determine the particle size distribution of the coarse and fine aggregates.This is done by sieving the aggregates as per IS: 2386 (Part I) – 1963. In this we use different sieves as standardized by the IS code and then pass aggregates through them and thus collect different sized particles left over different sieves.
