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.

Maximum size.The smallest sieve through which 100 percent of the aggregate sample particles pass. Superpave defines the maximum aggregate size as "one sieve larger than the nominal maximum size" (Roberts et al., 1996 [1]).

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)

Blue Metal 10mm - Quarried Sands and Aggregates

Blue Metal is a construction aggregate which is crushed and screened to a consistent size, making it ideal for various landscape designs or features. It can be used for paths, driveways, concreting, drainage pits and drainage filler in pot plants or stand-alone vegie beds.

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.

What are Aggregates? - MyAsphaltPavingProject.com

For asphalt pavements, different size rocks are crushed and aggregates are blended into graduated sizes to provide the strongest, best packing structure while allowing enough extra space for the asphalt binder and some "breathing" space (air voids).

Aggregates for Concrete - Department of Civil Engineering

aggregate size numbers. Fine aggregate or sand has only one range of particle sizes for general construction and highway work. The grading and grading limits are usually expressed as the percentage of material passing each sieve. Fig. 5-6 shows these limits for fine aggregate and for one size of coarse aggregate.
