Jan 17, 2020 Crush the cubes to test their strength – When each cube is ready for testing, it is put into a concrete crusher. This machine exerts force onto the cube until it breaks. The rate at which it crushes is measured, and this is its compressive strength. What size should the concrete cubes be?

Nov 13, 2017 Sep 11, 2019 1.373 x 10 x 10 = 137.3 Kn. So rate of loading will be = 137.3 / 60 = 2.88 Kn/Sec. Same way you can calculate rate of loading for each cube size you test at your laboratory. Kindly note above calculation are done considering your cube testing machine applies load in Kn, if your machine applies load in Kg or Mt kindly change the load on cube
