The 3, 5 or 7 day compressive breaks are not necessarily indicators for the 28 day breaks. If the material falls apart when removing the test cylinder, it is mostly likely excavatable or removable. A Performance Specification Option: Maximum 200 psi compressive strength (at 28 days)

Compressive Strength - an overview | ScienceDirect Topics

Compressive strength is the standard strength parameter of concrete that can be evaluated under site conditions as well. The most common method is to use cylinder cores drilled off the structure. Momber (1998b) was probably the first to suggest to use the way how a cylinder fails during the compression test as a criterion of the material behaviour during hydrodemolition.

How does Compressive Strength relate to Bearing Capacity ...

The "unconfined" compressive strength is equal to 2 times the undrained shear strength. For all intents and purposes the ultimate bearing capacity is 6 times the undrained shear strength (where c in cNc is the undrained shear strength) or 3 times the unconfined compressive strength.
