Proportioning of concrete mix
Design mix: • In this type, the concrete mix proportioning is determined on the basis of requirements of concrete on fresh and hardens properties (target mean strength). • And to get desired strength, special procedures is to be followed which are available in IS10262-2009 and IS456-2000.

Accordingly, the common mix design methods for conventional concrete are not suitable for guiding the mix design of 3DPC. Although some empirical mix design methods for 3DPC have been suggested in recent studies, there are still no commonly accepted mix design methods, which is not surprising given the brief history of research and applications with 3DPC.
