how to calculate concrete cube crushing pace

how to calculate concrete cube crushing pace

Answered How can we calculate the pace rate for CTM in crushing value test for aggre Aug 08 2019 . the stress under a 150mmx150mmx150mm cube is not sufficient to crush the concrete cube. Therefore 100mmx100mmx100mm concrete cubes are used instead to increase the applied stress to crush the concrete cubes.
