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) = 2.87; absorption capacity=
1.6%; dry-rodded unit weight = 121
lb./ft.3 surface moisture = 0.75%
• Fine Aggregate: Bulk specific gravity
(SSD) = 2.67; absorption capacity=
1.3%; fineness modulus = 2.70; surface
moisture 1.12%
