Concrete Crushing - an overview | ScienceDirect Topics

7/8/2010· 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.

Effect of Aggregates on the Properties of Concrete | .

The crushing strength test discussed above has been found insensitive to the variation in strength of weaker aggregates. Therefore when such aggregates are tested by this method, they do not give true picture, because they get crushed before the full load of 40 tonne has been applied and get compacted causing the plunger to jam.
