Aggregates larger than 475 mm in size are termed as coarse aggregates After considering the properties of the fine aggregates this section will deal with the coarse aggregates their properties and various tests according to the IS code for coarse aggregates
Aggregates larger than 475 mm in size are termed as coarse aggregates After considering the properties of the fine aggregates this section will deal with the coarse aggregates their properties and various tests according to the IS code for coarse aggregatesFurther Details
Aggregate is the loose granular materials in the concrete which has the function of skeleton and fill Common aggregate can be classified into coarse aggregate and fine aggregate The aggregates which particle size is larger than 475mm is called coarse aggregate including gravel crushed stoneFurther Details
For coarse aggregates ASTM C136 specifies that mass retained in kg shouldn’t exceed the product of 25 × sieve opening mm × effective sieving area m2 Allow enough time on a sieve shaker or testing screen for complete separationFurther Details
May 17 2020 · Fine aggregate Coarse aggregate When the aggregate particle is not passed through the 475mm sieve as per IS standard is called coarse aggregate The size of fine aggregate particles is less than 475mmFurther Details

The surface area of coarse aggregate is less than fine aggregates 6 Function in Concrete The voids between the coarse aggregate are filled up by fine aggregate Coarse aggregate acts as inert filler material for concrete 7 Uses Fine aggregates are used in mortar plaster concrete filling of road pavement layers etcFurther Details
After harvesting aggregate is processed crushed screened and washed to obtain proper cleanliness and gradation If necessary a benefaction process such as jigging or heavy media separation can be used to upgrade the quality Once processed the aggregates are handled and stored to minimize segregation and degradation and prevent contaminationFurther Details
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 depositsFurther Details
Coarse Aggregate When the aggregate is sieved through 475mm sieve the aggregate retained is called coarse aggregate Gravel cobble and boulders come under this category The maximum size aggregate used may be dependent upon some conditionsFurther Details
