Construction aggregate Wikipedia
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. Aggregates are a component of composite materials such as concrete and asphalt concrete; the aggregate serves as .

Tips on Aggregate Sampling for Sieve Analysis Gilson Co.
Aggregates play an important role in nearly all phases of highway construction. Quality assurance begins as samples are collected from the job site, prepared, and tested in the lab. This threepart series will cover sieve analysis of coarse aggregate, beginning from gathering samples at a job site, to preparing the samples and testing them in the lab.

Aggregates for Concrete GreenSpec
Coarse aggregates are particulates that are greater than The usual range employed is between and in diameter. Fine aggregates are usually sand or crushed stone that are less than in diameter. • Typically the most common size of aggregate used in construction is 20mm. A larger size, 40mm, is more common in mass concrete.

According to the suggestions in 1 coarse aggregate was eliminated in UHPC1 (Table 1). Only quartz sand in the range of to mm was used as aggregate. So UHPC1 is comparable to a RPC. In UHPC2 basalt splits with particles from 2 to 5 mm were used as coarse aggre gate, and the same sand in UHPC1 as fine aggregate.
