This conclusion was drawn from a series of tests in which Portland cement was ground either conventionally in a ball mill or in highpressure grinding rolls. The water demand of the ball milled cement was 27 per cent and of the highpressure ground cement was per cent, at the same specific surface area (350 m 2 /kg).
