Depends how big the bag is

4.50/bag cement, required for 1 cubic metre of concrete ( M10).
It would depend on how big the bag of cement is. 1 foot bags will be more in the cubic meter than 2 feet.
26 bags (40kgs cement bag)
one bag
volume of 1 cement bag is 0.035cu.m.
One cubic meter of concrete is equal to 1.308 cubic yards of concrete. If there are 5 1/2 bags of cement in 1 cubic yard of concrete, there would be 7.2 bags in 1 cubic meter of concrete. These are the 94 pound bags of portland cement or roughly 40kg bags so figure 8 bags total. Some will be left over
How many cubic meters in 1 cement bag of 50kgs
For M10 (1:3:6) Grade of concrete cement bag consumed = 4.4 bags/cum M15(1:2:4) Grade of concrete cement bag consumed = 6.6 bag/cum M20(1:1.5:3) Grade of concrete cement bag consumed = 8.2 bag/cum
For M25 grade concrete, the mix proportion is typically 1:1:2 (cement:sand:aggregate). This means for 1 cubic meter of concrete, you would need 1/4 cubic meter of cement. As 1 cubic meter is equivalent to 35.32 cubic feet, and one bag of cement usually covers around 0.035 cubic meters, you would need approximately 7-8 bags of cement for 1 cubic meter of M25 grade concrete.
To properly answer this question, one would need to know the volume of a "bag", since "bag" isn't any standard of volume or weight. Typical Portland Cement has a density to 1505kg / cubic meter. In addition, one would also need to know the coarseness of the gravel, as the ability of the sand and cement to fill in the aggregate depends heavily on the average size of the gravel pieces.
