EXTRACT: This project has investigated processing waste silt generated from aggregate washing recycling plants into secondary aggregate. The fine particles that constitute silt are filtered from water used to wash recycled aggregate. Aggregate washing plants are increasingly used because legislation and financial drivers are supporting increased use of secondary aggregates. Washing is beneficial because international aggregate standards limit the quantity of fine material (typically <63ìm) that should be included in recycled aggregate. To comply with these standards both recycled and virgin aggregate are washed. The wash-water contains fine silt particles which are removed by filtration so the water can be recycled. The resulting silt filter cake is a major waste disposal issue for the industry. This project had the overall aim of manufacturing viable aggregate from waste silt produced by aggregate washing
