no coarse aggregates concrete mixing design proportion

What is the mix proportion ratio for M30 grade concrete ...

Above M20 concrete their is no nominal mix proportion. M30 is the design mix of concrete where is 28days compressive strength is 30 N/mm2 and only 5% of samples can have strength below this. Normally ratio of fine and coarse aggts is 1:2 in any mix. Starting with this ratio design mix is prepared in lab of the quality of material available locally.
