There is no fixed rule for this. If manual mix, cement content shall vary between 350 ~ 400 Kg / M3.
Where as for Design mix (RMC), the cement content is decided by the supplier based on lot of other parameters and achieve the desired strength in 3, 7, 15 & 28 Days. Also PFA (Portland Fly Ash) shall also be added to some extent to arrive the desired strenth. The Cement & Fly Ash content shall be 300 / 80 kg per M3, to achieve the desired strength.
There is nominal mix up to M25 (1:1:2) proportion is available in I.S code, for above mix ratio you have to do mix design with knowing all material properties.
refer mix design from I.S code 10262-1999
500kg/m3
Concrete :- a mix of cement, sand, water, and gravel. Mortar :- a mix of cement, sand, and water
cement/ concrete is made with water, cement mixture and sand. After all of this is added to the right amount, you mix, mix, mix!! Then bofore it drys, pour it ontop the location desired
During concreting first of all we have to take an adequate quantity of aggregate,sand,cement& water according to standard mix design.Then prepare a proper mix which is nothing but concrete
Laen concrete contains very little actual cement. Laen cement is used as a base that is found under other cements. Ready mix concrete is used for primary uses of cement structures.
The answer is, remarkably, 6. Answer: "6 sack" or "6 bag mix" has six bags of cement per cubic yard of concrete mix. Since each sack/bag contains 94 lbs of dry cement, this equals 564 lbs of cement per cubic yard of concrete.
1:1:2
Water: cement: F.A.: C.A. = 0.4: 1: 1.65: 2.92Quantity of cement = 400 kgsNo.of bags = 8
cemet: sand: Agg=1:1:2 (Nominal Mix) Above answer is not as per engineering standards. For concrete mixing ration in M30 grade concrete, the mix has to be designed after testing all the materials including water in labs. When you go for higher grade of concretes the mix has to be designed , it is the water to cement ratio which has to be monitered for higher grades of concrete

The ratios of cement to sand to aggregate for the different grades of concrete are as follows. M10 has a ratio of 1:3:6. M15 has a ratio of 1:2:4. M20 has a ratio of 1:1.5:3. M25 has a ratio of 1:1:2, but M30 has no set ratio. It is a designed mixture to achieve the stress tolerance desired.

1:1:2 (1 cement: 1 sand: 2 coarse agregate)
Choose the grade of concrete & assume minimum water/cement ratio.Conduct some initial tests on the materials like cement, sand & metal(coarse aggregate).Tests like UNIT WEGHT, SPECIFIC GRAVITY,SIEVE ANALYSIS,SLUMP CONE TEST & COMPACTION FACTOR TEST. According to the obtained results do the mix design from IS CODE of IS800-10262 check for water cement ratio & calculate the quantity of cement, sand & coarse aggregate.
