Compressive Strength Prediction Model of High Strength Concrete by Destructive and Nondestructive Technique [PDF]
E3S Web of ConferencesConcrete’s compressive strength can be tested in a laboratory before construction begins. Since concrete is a natural material and cannot be destroyed, it is not possible to determine its compressive strength through destructive testing.

Assessment techniques for the evaluation of concrete structures after fire [PDF]
, 2013 As concrete structures exposed to fire behave in most cases very well, it could be of economic interest to repair the fire damaged structure. For this purpose a damage assessment based on scientific research is required as first step.
