Question
Consider the following example: The 28-day compressive strength should be 4,000 psi. The slump should be between 3 and 4 in. and the maximum aggregate size should not exceed 1 in. The coarse and fine aggregates in the storage bins are wet.
The properties of the materials are as follows:
• Cement : Type I, specific gravity = 3.15
• Coarse Aggregate: Bulk specific gravity (SSD) = 2.70; absorption capacity = 1.1%; dry-rodded unit weight : 105 lb./ft.3 surface moisture = 1%
• Fine Aggregate: Bulk specific gravity (SSD) = 2.67; absorption capacity = 1.3%; fineness modulus = 2.70: surface moisture = 1.5%
5. What is the estimated batch weight of wet coarse aggregates in Ib/yd^3?
