· The compressive strength of concrete is given in terms of the characteristic compressive strength of 150 mm size cubes tested at 28 days The characteristic strength is defined as the strength of the concrete below which not more than 5% of the test results are expected to fall." Number of samples for testing Compressive Strength
· Dry crushing is seldom carried below about ½-in. particle size, experience having shown that the breaking of material beyond this point is more satisfactorily accomplished by wet methods. On the other hand, there is a trend today toward feeding considerably coarser material to rod mills which function to some extent as wet rolls.
