Gradation and Size - Pavement Interactive

The particle size distribution, or gradation, of an aggregate is one of the most influential aggregate characteristics in determining how it will perform as a pavement material. In HMA, gradation helps determine almost every important property including stiffness, stability, durability, permeability, workability, fatigue resistance, frictional resistance and moisture susceptibility (Roberts et ...

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. The cumulative percentage retained on each sieve is added and subtracted by 100 gives the value of fine aggregate.

wanted. Specifying the size of the aggregate for the job then becomes a very important decision for the purchaser. Coarse aggregates are classified as open-graded and dense-graded. One of the difficulties with use is a tendency of aggregate sizes to segregate in handling.

Aggregate Sizing Explained - Chaney Enterprises

Jan 15, 2016· For example coarse aggregate has a standard grading requirement for each different size from #1 to #8. A #1 aggregate is a nominal size of 3 ½ to 1 ½ inches and a #8 aggregate is a nominal size of 3/8 to 0.094 inch. More specifically, a #57 aggregate is the combination of #5 and #7 aggregates ranging from 1 to 0.19 inch.

Aggregate Properties - The Concrete Portal

A maximum size up to 40 mm is used for coarse aggregate in most structural applications, while for mass concreting purposes such as dams, sizes up to 150 mm may be used. Fine aggregates, on the other hand, have particles up to a minimum size of 0.075 mm. Typical particle size analyses of coarse and fine aggregates are shown in Figure 1.

Sieve analysis - Wikipedia

Sieve analysis has, in general, been used for decades to monitor material quality based on particle size. For coarse material, sizes that range down to #100 mesh (150μm), a sieve analysis and particle size distribution is accurate and consistent. However, for material that is finer than 100 mesh, dry sieving can be significantly less accurate.

ACI 211.1: Maximum Aggregate Size For Concrete Mix Design

In this post I shall discuss maximum aggregate size that can be used in design. Large maximum sizes of aggregates produce less voids than smaller sizes. Hence, concretes with the larger-sized aggregates require less mortar per unit volume of concrete, and of coarse it is the mortar which contains the most expensive ingredient, cement.
