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.

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

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

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

What is grading of Aggregates? Please explain me.
