The Unified Soil Classification System (USCS) is a soil classification system used in engineering and geology to describe the texture and grain size of a soil The classification system can be applied to most unconsolidated materials, and is represented by a twoletter symbol Each letter is described below (with the exception of Pt): If the soil has 5–12% by weight of fines passing a #200 sieve (5% < P#200 < 12%), both grain sConcrete aggregates are composed of geological materials such as gravel, sand and crushed rock The size of the particles determines whether it is a coarse aggregate (eg What Are Aggregates and How Are They Used?

Sand, gravel, and bedrock may be mined or quarried to produce raw materials known as 'construction' aggregate Construction aggregate is used for road base and stabilization 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 Aggregates for Concrete
