Because if the different size and shape of agg are mixed with each other. The bonding is become strong.

I have same opinion that @Rakesh has said. If mixed particle are being used the small particle fills gaps generated between big particle, in fact increases bonding strength.

The pores of sand is filled by cement, then the pores of coarse aggregate is filled by sand (fine aggregate) where its effective strength will come by adding chips (12mm) coarse aggregates.

Different size of particles gives more strength, because bonding becomes stronger.

If different size of particles are present then the gaps will filled properly and bond become strong.

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.

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.

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.
