Determine the quantities of materials required per cubic yard tocreate a concrete mix. The specifications require a maximum sizeaggregate of 3/4 in., a minimum cement content of 6 sacks per cy,and a maximum water-cement ratio of 0.5. Assume 7% air voids.Consider the ratio of course aggregates to be 65% of the totalaggregates by volume. Please refer to the standard weights &densities (at the end of the test) for specific gravities and unitconversions.
