Use the list below of design requirements/assumptions to come up with the concrete mix design: A slump of 10mm to 30mm. A characteristic 28-day compressive strength of 30 N/mm2 (5% failures permitted). The standard deviation of the tests is o = 6.1 N/mm?. Ordinary Portland cement (42.5 N). Crushed sand of 2.7 density and 60% passing through a 600 um sieve. Crushed coarse aggregate 2.6 density and 20mm are used.
