General Introduction. The two functional groups I deal with here are the C,C double bond and the C,C triple bond. In each case the group is named by changing the letter a in the suffix ane to e for the double bond and to y for the triple bond.otes: 1  Examples 1 and 2 show the use of E/Z for routine alkene structures for which cis/trans could have been used. 2  Examples 5 and 6 show how the rules require you to move down the chain away from the stereocentre (the double bond) until a difference is found. 3  Example 6 illustrates that the functional group named as a prefix takes precedence in ...
compressive strength Definition. The resistance capacity of any material, but especially structural members, to crushing force. Compressive strength is usuallyexpressed as the maximum number of pounds per square inch that can be resisted without failure.
CIP 35 - Testing Compressive Strength of Concrete WHAT is the Compressive Strength of Concrete? Concrete mixtures can be designed to provide a wide range of mechanical and durability properties to meet the design requirements of a structure.ompressive strength is measured by breaking cylindrical concrete specimens in a compression-testing machine. Compressive strength is calculated from the failure load divided by the cross-sectional area resisting the load and reported in units of pound-force per square inch (psi) or megapascals (MPa).
