No gradation will perfectly follow the straight middle line, but as long as the gradation falls within the zone of the two outer lines, the grading will have a high packing density. The coarseness chart is not a grading system, it is simply a chart that helps ensure uniform blends of aggregate without major gaps in grading (Shilstone, 2002).

aggregates cannot be overemphasized. The fine and coarse aggregates generally occupy 60% to 75% of the concrete volume (70% to 85% by mass) and strongly influ-ence the concrete's freshly mixed and hardened proper-ties, mixture proportions, and economy. Fine aggregates (Fig. 5-1) generally consist of natural sand or crushed

The skid resistance was also affected significantly by the gradation, as represented by the composition index, of the aggregates. For the unpolished specimens, the British portable number (BPN) is shown to increase with increasing values of the composition index.

Combined Aggregate Gradation as a Method for Mitigating ...

One of the ideas also tried was a switch from the standard aggregate gradation specification to a combined gradation specification. The theory was that the near gap grading of the standard specification might be a contributing factor to the increased wear and that a combined gradation with its more uniform grading would help to mitigate this wear.

All samples for testing are determined using a random number chart and multiplying the random number by the sampling rate as defined in the Schedule of Materials Control. On the Combined Gradation Chart tab and Coarseness Factor Chart tab below, there are five gradation charts which contain 12 combined gradation test results each.


The Third Edition of the Earth Manual contains new or revised soil testing procedures as compared to the Second Edition (1974).

Gradation Ensure that the finished product meets the quality and gradation requirements of Subsection 815.2.01 for Group II aggregates, except that the aggregate will be recycled concrete.


6. If more than one type of coarse aggregate is being used, first find the optimal composition of the blend and then determine the characteristic diameter and packing density of the combined aggregate as described in steps 1 and 2. Then find the optimal composition of the combined aggregate with the sand.

Regardless of its practical use, a maximum density gradation provides a convenient reference. In 1907, Fuller and Thompson developed a widely used equation to describe a maximum density gradation for a given maximum aggregate size. This equation is: Where: P = percent finer than an aggregate size; d = aggregate size being considered

For fine aggregates, the fineness modulus ranges from 2.00 to 4.00, while coarse aggregates range from 6.50 to 8.00, when all material is finer than 1-1/2 in. (38.1 mm). Combined gradations will range from 4.00 to 7.00. The "8-18" Rule is one method to characterize an aggregate blend.

Grading of Aggregates - Aggregate Grading | The Construction ...

In grading of aggregates, the voids in the mixed aggregate would be minimum when the sand is just sufficient to fill the voids in the coarse aggregate. Voids in the coarse aggregate are filled in by sand and voids in the sand are filled in by cement. Mix that occupies the least volume is the densest and will produce the best results.
