You need to calculate the total volume of the space that the concrete has to fill.
if you're doing a slab 4" thick a cu. yd. will cover 81 sq. ft. Take the total area
and divide by 81 to get the number of yard needed.
calculate the volume of concrete you need to pour and multiply the volume with concrete density (2400kg/Cu.m), then you will get the total weight of the conctere. then the weight of concrete divided by the total ratio (for eg. M20 mix, 1:1.5:3, total ratio is 5.5)you will get 1 part cement weight (in kg) and then 1 part multiplied by 1.5 for fine aggregate and 1 part weight multiplied by 3 for coarse aggregate.
You have measure ratio of cement sand and aggregate

There is no way to calculate cost for a square foot of concrete (?" w x ?" l). In order to calculate cost you need to first calculate volume which requires a third dimension of height (?" w x ?" l x ?" h). Concrete is usually sold by the cubic yard (36" wide x 36" long x 36" high). Another factor in calculating price of concrete is distance to delivery location.
Considering the different applications and methods of concrete construction, you really can't calculate it that way.
By using IS code(456-2000) for reinforced cement concrete.
Steel reinforcing rods have minimum overlap requirements to ensure that the reinforcing has a continuous effect throughout the structure.In some instances this minimum overlap is 600mm, but the requirement does vary and must be confirmed by an Engineer for each particular design.Maximum overlaps would be used to ensure wastage is reduced, and to ensure adequate concrete cover.

how calculate steel in concrete
length*breadth*depth of the structure=...........m3 of concrete is needed. .
The designers calculate the potential effects of cracking on the concrete columns.

anything that's not liquid wastage.
Allow 5.5 to 6 yards. Always allow for wastage, underrunning forms, etc.
Wastage is accented on the first syllable.
How thick? Gotta have thickness to calculate cubic yards.
The depth of the pour would also be necessary to calculate the volume of concrete needed.
It is just a wastage of time.
If the room is rectangular, just multiply length x width. For the 10% wastage, multiply the result by 1.10 - that's the same as adding 10%.
