Cylindrical strength = 85% of Cube strength.
The equivalent concrete for M-30 cylinder strength is M-40 cube strength
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.
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').
To calculate the volume of a cylinder of concrete, you can use the formula: ( V = \pi r^2 h ), where ( V ) is the volume, ( r ) is the radius of the base, and ( h ) is the height of the cylinder. Ensure that the radius and height are in the same units to obtain the volume in cubic units. If you need the weight of the concrete, multiply the volume by the density of concrete, typically around 2,400 kg/m³.

To fill half of a cylinder, you would need to calculate the volume of the cylinder and then divide it by 2. The formula for the volume of a cylinder is πr^2h, where r is the radius and h is the height. Once you have the volume, you can convert it to cubic yards by using the appropriate conversion factor.
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.
You will need 1.31 cubic feet for a cylinder that is 3' wide x 5' tall.

13.5 cu ft
The volume of a cylinder with 6 feet as the diameter and 12 feet as the height is 339.29 cubic feet.
