Below 4.75 mm only fine aggregate as IS.

Kushal said:   1 decade ago
80, 40, 20, 10, 4.75 ----->> Coarse aggregates.

4.75, 2.36, 1.18, 600 micron, 300 micron, 150 micron ---->> Fine Aggregates.

What is cyclopean aggregate?

Arun said:   1 decade ago
The aggregate of size more than 75 mm are called Cyclopean aggregate. Since the Max size of coarse aggregate is 75 mm.

Darshan said:   9 years ago
The answer is coarse aggregate.

Xylo said:   9 years ago
Actually, the question is wrong as coarse aggregates contain 20mm and 40mm aggregates also not only 10mm. And max sieve size to determine the size of fine aggregates is 4, 75.

Adhi said:   9 years ago
Answer is correct.

Because 4.75 is sieve acts as a mediator,

In 4.75 sieve, all coarse aggregates gets retained, while all fines get collected in the pan.

@ALL.

As give IS sieve no 10 and 4.75 mm it means #10 is 2 mm size which is used for fine aggregate and 4.75 used both fine and coarse aggregate.

Course aggregate is the only correct answer.
