This cylinder will require 1.4 cubic yards of concrete (this assumes a length of 12' and a width of 2').
You will need 1.31 cubic feet for a cylinder that is 3' wide x 5' tall.
how much does a gallon of concrete weigh
You can't get much more concrete than something that big.
7 gallons
The term slump used in concrete means the thickness or thinness of the concrete. The slump is measured by filling a 12" cylinder up with concrete, then flipping it over and pulling the cylinder up. The distance the concrete "slumps" down from the top of the cylinder is the slump for that concrete. For example, if the concrete falls 6" from the top of the cylinder, that concrete is on a 6" slump.
13.5 cu ft
When dealing with conrete the "slump" refers to how much will a sample sag, reduce in height in a given time frame. re: a 5" slump means that after removing the CYLINDER the concrete will lose 5 inches of elevation. The slump cylinder is the tool used to determine the slump of concrete.
The equivalent concrete for M-30 cylinder strength is M-40 cube strength
A concrete pump which comprises an elongated hollow housing in which a valve element reciprocates. The valve element includes a pair of transversely extending tubes and a pair of concrete guiding chambers. The valve element moves between two positions. In the first position a first guide chamber is opposite a first pump cylinder and guides concrete from an upright conduit associated with the first pump cylinder into the first pump cylinder and a first tube is opposite a second pump cylinder and guides concrete from the second pump cylinder into a discharge line associated with the second pump cylinder. At the second position a second guide chamber is opposite the second pump cylinder and guides concrete from an upright conduit associated with the second pump cylinder into the second pump cylinder and the second tube is opposite the first pump cylinder and guides concrete from the first pump cylinder into the discharge line associated with the first pump cylinder.
This cylinder will require 1.4 cubic yards of concrete (this assumes a length of 12' and a width of 2').
Cylindrical strength = 85% of Cube strength.
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.

It would be much easier to calculate an answer if we knew the dimensions of the cylinder. A drinking straw cannot hold as many cubic yards as a section of 12-ft concrete sewer pipe.
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.
The volume of a cylinder with 6 feet as the diameter and 12 feet as the height is 339.29 cubic feet.
