Concrete Crushing an overview ScienceDirect Topics. Aug 07, 2010· An analysis of the abrasive wear of concrete floors has revealed that high-intensity crushing is the chief mechanism of deterioration, and hence the concrete crushing strength is the relevant parameter determining wear resistance. 248 Generally, the abrasion resistance of the coarse aggregate component is not related to the
ASTM C39, Standard Test Method for Compressive Strength of Cylindrical Concrete Specimens, specifies that the loading rate fall within 0.14 to 0.34 MPa/sec (20 to 50 psi/sec). On average, the compressive strength of cylinders tested at the high load rate limit will be 3% greater than cylinders tested at the low load rate limit.

07-08-2010· The desired concrete crushing failures shown in Figs. 1.24 and 1.25 can only be achieved if IC, CDC and PE debonding can be prevented from occurring before the design load to cause concrete crushing. However, this may not always be possible; in which case, it may be necessary to design for either IC or CDC debonding to occur at the design load so that concrete crushing will not occur.
The cubes are tested on the face perpendicular to the casting face. The compression machine exerts a constant progressing force on the cubes till they fail, the rate of loading is 0.6 ± 0.2 M/Pas (N/mm²/s).
