The specimen will break at maximum load (1 Division = 5 KN), which is noted down as the crushing value of the cube. The average (Minimum Three Sample) crushing value should be note down as the compression value of the selected concrete batch.

2010-08-07· 5.4.1 Concrete Crushing Concrete crushing after yielding of steel reinforcement represents an under-reinforced member, which is typical of current reinforced concrete design standards. This failure mode ensures that a high level of member ductility is maintained prior to failure, thus providing ample warning before collapse.

2020-09-01· When the crushing head just contacts with the specimen, the inertia of the specimen shall be overcome by the load of the crushing head and it obtains a uniform compression rate (1 m/s). In an ideal condition, the specimen deforms uniformly and its lower surface speed is 0, its average velocity is half of that of the crushing head (0.5 m/s).
