To attain maximum aggregate packing density, empirical approaches typically used in the U.S. aim to achieve a ÎcontinuousÌ, also known as Îwellgraded'', combined aggregate grading or particlesize distribution. ÎCombinedÌ in this context refers to a combination of both coarse and fine aggregate grading in the ratio that they are present in

Figure 5: Gradation and size equipment. Fuller and Thompson''s Equation (Interactive Equation) 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. NCHRP Report

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 each sieve as a fraction of the whole mass.
Jul 07, 2014 · IS specifiions classify the fine aggregate into four types according to its grading as fine aggregate of grading Zone1 to grading Zone4. The four grading zones become progressively finer from grading Zone1 to grading Zone4. 90% to of the fine aggregate passes 4.75 mm IS sieve and 0 to 15% passes 150 micron IS sieve depending upon

Grading of Aggregates. Grading of Aggregates is one which is made up of stones of different sizes, ranging from large to small (inclusive of sand) so as to have minimum of air voids (and that will have maximum density) when mixed together 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.
