what are the metal aggregate sizes

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.

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.

Aggregate gravel options for drainage behind rock retaining wall

Aggregate gravel options for drainage behind rock retaining wall I've gone overboard with drainage behind our new rock retaining walls. Given they cost $15k (5 separate walls totalling approx 50 metres in length and between 200 and 1000mm in height), I figure it's worth the investment.

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.
