4000PSI, 12bags, .5cum3sand 1cu.m3 gravel
26 bags (40kgs cement bag)
It depends on the size of the bags
11 bags
You will need 5.5 40kg bags for this floor. This allows for a typical waste factor of 5%
7 cement bags per 1 cubic meter of concrete......
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
According to Blue Circle it takes 108 bags of concrete to get a cubic meter
26 bags
It would depend on how big the bag of cement is. 1 foot bags will be more in the cubic meter than 2 feet.
it is 100 bags of sand/ballast
The answer will depend on how big (or small) the bags of sand are!
