Concrete Mix Design for M30 grade
Concrete mix Design for M30 Grade concrete with fly ash is as follows;


OPC Cement 53 Grade – 320 Kg

Fly ash – 80 Kg

Water Cement ratio (w/c) – 0.38

Free Water – 152 liters

20mm Metal / Aggregates – 464 Kg

10mm Metal / Aggregates – 442 Kg

Crush Sand – 739 Kg

River Sand – 362 Kg

Admixture Dosage – 0.8 %

Admixture – 3.2 Kg

Density of Concrete – 2562 Kg/cum

The complete mix design file is attached herewith.

You can modify the mix design by changing the specific gravities of materials which will make it relevant as per the material available at your place.
Changing the specific gravity will change the weight of material in mix design which is automatically calculated.
Do not use this mixes directly without doing prior trials of it, the data provided is for educational and better understanding of mixes.
After doing trial, if any issue observed, you can do adjustment by adjusting the % of each size of aggregate to achieve the required properties of fresh concrete.
Do ensure total of all aggregate percentage in mix should some to 100%

In general, for direct placement concrete
Ration of fine aggregates to coarse aggregates kept between 35:75 to 40:60
In case of pump concrete the fine content is kept above 45%
You can adjust the percentages of fines and coarse by looking at the concrete produced during trial.

Admixtures plays an important role in properties of fresh concrete specially in workability and retention.
Do select admixture correctly to ensure no failure during actual use of concrete.

All can reply to this thread with there mix design of same grade, this will help other to understand designing in more better way and can do a cost optimization.
