Construction aggregate, or simply "aggregate", is a broad category of coarse to medium grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined materials in the world.

### Shape, Size - Coarse Aggregates

Coarse aggregates are classified into two main groups: (i) single-size aggregate and (ii) graded aggregate. Single-size aggregate is based on a nominal size specification. It contains about 85 to 100 percent of the material which passes through that specified size of the sieve and zero to 25% of which is retained in the next lower sieve.

### Aggregates for Concrete - Portland Cement Association

Coarse-Aggregate Grading. The maximum size of coarse aggregate used in concrete has a direct bearing on the economy of concrete. Usually more water and cement is required for small-size aggregates than for large sizes, due to an increase in total aggregate surface area.

### Aggregate Sizing Explained - Chaney Enterprises

· 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.

### MATERIALS of CONSTRUCTION Lab Application -Testing of ...

If this ratio is higher than 3, than the particle is too long (non-cubic particle). EN 933-4 sets down the amount of measured grains to minimum 100 grains from each size of the coarse aggregate. Shape index SI is defined as a ratio between the weight of particles with L/E 3 and weight of all measured particles in percents.

### Function and Importance of Aggregate in Concrete

· • Coarse aggregate is used to describe particles larger than 4.75 mm, and the term fine aggregate is used for particles smaller than 4.75mm; typically, fine aggregates contain particles in the size range 75 µm to 4.75 mm, and coarse aggregates from 4.75 to about 50 mm, except for mass concrete which may contain particles up to 150 mm.

· It is the aggregate composed of both fine aggregate and coarse aggregate. According to size All-in-aggregate is described as all-in-aggregates of its nominal size, i.e. 40mm, 20mm etc. For example, all in aggregate of nominal size of 20mm means an aggregate most of which passes through 20 mm IS sieve and contains fine aggregates also.
