Generally the size of coarse aggregate used is mm. If we use the proportional mix of different sizes small to large (> mm to 20/25 mm), this make the concrete structure compact by align themselves in voids depending upon their size and compact mass will be formed with increased strength.

In general for strength upto 200 kg/cm2 aggregates upto 40 mm may be used and for strength above 300 kg/cm2 aggregate upto 20 mm may be used. The following conditions decide the maximum size of coarse aggregate to be used in concrete.
Aggregate is classified as two different types, coarse and fine. Coarse aggregate is usually greater than mm (retained on a No. 4 sieve), while fine aggregate is less than mm (passing the No. 4 sieve). The compressive aggregate strength is an important factor in the selection of aggregate.

It is advantageous to use greater maximum size of coarse aggregate for concrete grades up to M 35 where mortar failure is predominant. Lower water/cement ratio will mean higher strength of mortar (which is the weakest link) and will result in higher strength of concrete.
