Design a non‐air‐entrained concrete mix that will have a slump of 3 4" and a design strength (f′c) of 4300 psi using the absolute volume method. Assume the following agg egate properties:
Natural Sand Fineness modulus = 2.90 Absorption = 1.25% Bulk relative density = 2.55 Dry‐rodded unit weight = 106 lb/ft3
Gravel w/ some crushed particles NMAS = ¾" Absorption = 0.95% Bulk relative density = 2.66 Dry‐rodded unit weight = 99 lb/ft3
Don’t forget to adjust the water content for the shape of the coarse aggregate. Also, make sure you add enough extra water to your mix design the make the aggregate SSD (but you don’t know the moisture content of the aggregate yet, so ignore the last two parts of Step 10). Do all calculations based on a cubic yard of concrete.
