Determine the batch quantities for a concrete mix design to have a 28-day compressive strength of 4000 psi, using sub-angular aggregate .The fine aggregate has a fineness modulus of 2.5. The concrete is used in severe weather, however we will use non-air entrained. A slump of 3 in is desired. Use a 350 psi standard deviations of compressive strength of concrete (more than 30 samples).
