The Charpy Considering the many uncertainties that yet exist about the precise nature of the cracking process, and indeed even about the notch sensitivity of these materials, it should not be surprising that there is still no agreement as to which fracture mechanics criteria best characterize the failure of cement or concrete, or which test methods are most suitable. During the casting of test specimen initial crack was introduced. Six groups of beams, including a plain concrete control, two different volumes of polypropylene fibers, and three different volumes of steel fibers were … reinforced concrete (SFRC) are compared and evaluated u ing live CJ'iteria.
