Recycled Aggregate Concrete, Nov 15, 2014· It is called recycled aggregate which can be produced by concrete crusher The aggregates are categorized by size as coarse and fine aggregate The characteristic of recycled aggregates could be different by its parent concrete because the parent concrete was designed for its purposes such as permeable, durable and high strength concreteExperimental Investigation on Concrete with Replacement of ,, Consequently, these process coarse aggregates utilize in the concrete in cast-off aggregate and concrete  Advertisements The discarding of building waste is 5000 tons per day in Overall analyzation in India and South Asia According to Hindu also 2375 ,1120 Lightweight Aggregate Manufacturing, 11201 Process Description1,2 Lightweight aggregate is a type of coarse aggregate that is used in the production of lightweight concrete products such as concrete block, structural concrete, and pavement The Standard Industrial Classification (SIC) code for lightweight aggregate manufacturing is 3295; there currently is no Source ,Aggregates for Concrete, blast-furnace slag is also used as fine or coarse aggregate The aggregates are usually washed and graded at the pit or plant Some variation in the type, quality, cleanli-ness, grading, moisture content, and other properties is expected Close to half of the coarse aggregates used in portland cement concrete in North America are gravels;5 Aggregate Production, aggregate physical properties, and, in particular, gradation (size control) 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.
