Fine Aggregates: Types, Properties & Uses in construction
Introduction to fine aggregates: The maximum size used is 80 mm and the range of 80 mm to 4.75 mn is known as coarse aggregate and 4.75 to 150 µm is called fine aggregate. Size 4.75 mm is common for both fine and coarse fractions. Qualities of fine aggregates: Fine aggregate should be clean i.e. it should be free from lumps, organic material, etc.

Answer: There is a range defined for classification of aggregate. So according to sieve size, the aggregate passing through 4.75mm sieve is termed as fine aggregate and retained on 4.75 mm sieve is termed as coase aggregate. So the range of coarse aggregate is 4.75mm to 80mm. Therefore minimum ...

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.
