Aggregate in Concrete - The Concrete Network
The maximum size of coarse aggregate that can be used in a mix depends on the size, shape, and reinforcing of a member, based on these "not-to-exceed" guidelines (see Photos 5 and 6): 3/4 of the clear spacing between rebar or between rebar and forms (cover distance)
Sieve Analysis of Aggregates - Civil Engineering
sieve analysis 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 ...

Shape, Size - Coarse Aggregates
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. A graded aggregate contains more than one single-size aggregate.

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.
Aggregate Properties - The Concrete Portal
Typically, coarse aggregate sizes are larger than 4.75 mm (5 mm in British code), while fine aggregates form the portion below 4.75 mm. 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.

Classification of Aggregates Based on Size. Aggregates are available in nature in different sizes. The size of aggregate used may be related to the mix proportions, type of work etc. the size distribution of aggregates is called grading of aggregates.
Heavy metal distribution between soil aggregate core and ...
The increasing enrichment of Cu, and, to a lesser extent, Cd in the aggregate surface compared with the core fractions at the DOR-sites with increasing heavy metal burden may be explained by preferential sorption of deposited heavy metals to aggregate surfaces (Wilcke and Kaupenjohann, 1994).

Aggregate (composite) - Wikipedia
Aggregate is the component of a composite material that resists compressive stress and provides bulk to the composite material. For efficient filling, aggregate should be much smaller than the finished item, but have a wide variety of sizes. For example, the particles of stone used to make concrete typically include both sand and gravel
