A concrete mix exposed to moderate freeze-thaw but no deicers or sulfates, is specified to have a water-cement ratio of 0.40 based on strength and durability requirements. The required slump for the fresh concrete is 3-4 inches. The concrete is to be air-entrained. The properties of the aggregates to be used are given below. Proportion the ingredients for one cubic yard of concrete using the Absolute Volume Method. Write a mix summary and compute the unit weight of the designed concrete. Use the tables on the formula sheet for this problem.
