Aggregates for Concrete

aggregate and crushed stone coarse and fine aggregate are produced by crushing natural stone Crushing, screening, and washing may be used to process aggregates from either sand and gravel deposits or stone quarries Aggregates may be produced from igneous, sedimentary, or metamorphic rocks, but geological type does not by itself make an aggregateAggregate material may be anything from a densegraded crushed aggregate to a granular soil having a relatively high percentage of dust At the time of mixing, the aggregate may either be damp, airdried, or artificially heated and dried Mixing methods may be performed either in the roadway, on the side of the roadway, or in a stationaryChapter 2 Asphalt and Asphalt Paving Materials
