THE MIX DESIGN METHOD CHOICE AND RATIO OF AGGREGATES The coarse aggregates most employed in concrete block production are those that pass through a 3/8 in (9.5 mm) sieve and are retained by a number 4 (4.8 mm) sieve. Preferably, the aggregate particles’ shape must be cubic, which allows use of larger amounts in concrete mixtures The weight ratio of cement and mineral powder to the concrete density varies between 9.44–29.77% and 1.26–15.79% respectively. While the ratio variation for combined weight of cement and mineral powder is between 18.98 and 42.53% in the LWSCC mix designs. 7.2.
