The answer depends on which one of the measures is the length (height) and also on whether the other measure is the radius, diameter or circumference.
1 cubic yd of a concrete mixture contains about 500 hundred lbs of cement
260 kg/cu m
What you need to do first is to check if you have that room near the threshold of the door for that extra concrete(which is minimum of 3.5" inches) then you need to remove the top surface of the old concrete to be rough surface don't break too much just about an 1"wash clean and let it dry and only then to install the new concrete.
How much cement sand and stone do you need for 1 cubic meter of concre
1 and half tons
For a 4-inch depth you will need at least 7 cubic yards.
For a 4-inch depth you will need at least 7 cubic yards.
For a 4-inch thick slab you will need at least 1.2 cubic yards.
At least 3 cubic yards for a 4-inch slab. You'll need 4.75 cubic yards for a 6-inch slab.
That depends on how deep (thick) you need it to be. You'll need 1 yard of concrete for every 3/4 inch of thickness of the pad.
For a 4-inch depth: 4.75 cubic yards. For a 6-inch depth: 7.1 cubic yards.
1.25 cubic yards for a 4-inch slab. 2 cubic yards (1.85) for a 6-inch slab.
5.21073504 (gal us).... 4.3467648 (gal UK).... that doesn't help for in but im an auzzy and i don't need the answer...
Weight will depend on the size of the cylinder, and whether it is solid or hollow like a pipe. You said 2 foot round, but do you mean diameter or circumference- and how tall is the cylinder? We need more information to answer this.
for ,this we need to calculate the volume of concrete . volume of concrete = L x B Xh. =17 X 4 X24 . =1632 inch cube. Thus,1632 cubic inches concrete is needed for 17 inch by 24 inch by 4 inch deep .
A 22x22 foot slab at a 4-inch thickness/depth requires a minimum of 6 cubic yards.
