Design a concrete mix for the superstructure of a building using DoE mix design method requiring a characteristic strength of 40MPa at 28days and a slump of 30-60mm. The materials available are ordinary Portland cement, and uncrushed fine and coarse aggregates of specific gravity of 2.65. The maximum nominal size of coarse aggregate is 10mm and fine aggregate confirms to the grading zone III. Neglect the effect of standard deviation and other factors.

Using the absolute volume method, a colleague started a mix design for a simple concrete foundation in a mild climate and got through Step 5 and has asked you to finish the work. They have already determined the mix needs: • a w/c ratio of 0.45 • a 2” slump • 1830 lb of gravel in the oven dry conditions, • and 3.5% air provided by air entrainer. The available gravel (coarse aggregate) is subangular with a NMSA = 3⁄4”....
