What is grading of Aggregates? Please explain me.

The graded aggregate increases the properties of concrete.
Bonding between particles is good.
Bonding between particles is good.

Otherwise concrete will become HONEYCOMBED.
Grading gives good quality of aggregate because all pores will get filled with different sizes of particles ie. Spaces between coarse aggregate will be filled by sand and the gap between sand particles get filled by cement, resulting in a dense cake of concrete.

Grade is important because mix proportion is accurate so strength increase.

Because when all voids fill in the concrete mix then it got more compact and having high strength.

Graded means a dive analysis practical mostly rounded particles USD but some of the pours due to used differently grading.

By the using different size of particles all the gapes (pores) are closed (filled). So that bonding is increased.

Graded aggregates mean different fraction is available & it effect on workability, interlocking and fill up the voids in the concrete.

Remember we have different grades of aggregate, we have uniformly graded, poorly graded and well graded or All in aggregate. Which is best 4 concrete cos it has a better bonding interface to form a single cohesive mass.

We can also say this to ensure the quality apart from other parameter Aggregate should be well graded/ graded (can be ascertain by combine sieve analysis) should not gap graded. If we use single graded aggregates, the cement & sand paste will be spread unevenly & creation of gap will happen causing unsound, not well bounded concrete.
