• Aggregates Portland Cement Association

    Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete. After harvesting, aggregate is processed: crushed, screened, and washed to obtain proper cleanliness and gradation.

    The technical process of manufacturing M-sand gives the sand particles a rough cubical shape with rounded off edges, allowing it to create stronger bonds between the cement and the coarse aggregate. This same technology allows the manufactured sand grains to be graded, so that a specific size distribution can be maintained.

    A World of MineralsAggregate ProcessingGeneral Kinematics Processing EquipmentDuring processing, aggregates are distilled down to a level of their most common use. Some aggregates may be crushed to a powder while others may be screened to various diameter chunks. The proper processing of aggregates is important in maintaining their desirable qualities. For instance, between 60 and 75 percentof concrete consists of both coarse and fine aggregates. If the aggregates are not properly sized, as well as clean and free from other matter, the concrete could fail to meet its desired strength a

    A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel (aggregate) together. Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete. Concrete is the most widely used material in existence and is only behind water as the planet's most-consumed resource.
