  • Manufactured Aggregate an overview ScienceDirect Topics

    EN 12620 6 defines manufactured aggregate as aggregate of mineral origin resulting from an industrial process involving thermal or other modification This is used to cover materials that have been deliberately manufactured by processes involving more than just mechanical processing of natural rock, sand or gravel, and aggregates that are byproducts of another industryManufactured aggregate mainly refers to machinemade aggregate(manufactured sand and crushed stone) Rock particles (excluding soft and weathered rock particles) processed by natural rock, river pebble stone or mine waste rock through mechanical crushing, shaping, screening, powder control and other processes, including:Manufactured Sand and Crushed Stones Processing The production of manufactured aggregates requires varying degrees of processing depending on the materials being used To provide an overview of this the production of manufactured aggregate byManufactured Aggregates GOVUK  Establishing a stable production process may reduce variability of the product EXTRACTION With the exception of slag and other manufactured aggregates most materials for aggregate production come from bedrock or unconsolidated deposits The vast majority of materials used in the mineral aggregate industry are5 Aggregate Production in  Manufactured aggregatesMaterials produced by agglomeration and curing with properties that meet standard specifications for construction aggregates (eg AASHTO, ASTM) MixingA process step to blend the feedstocks (combustion byproduct, recycle dry fines, and aluminumcontaining material, and water) to form a feed mix prior to agglomerationMethod for making manufactured aggregates from coal
