A concrete mix design is needed for a residential street pavingproject in Detroit, Michigan. Pavement thickness is 8â€,unreinforced, subjected to freezing and thawing and deicing agentsare anticipated. The specified compressive strength is 4000 psi.Assume both Fine Aggregate (FA) and Coarse Aggregate (CA) are insaturated surface dry condition.
Specific Gravity of Fine Aggregate (FA) = 2.71
Fineness Modulus (FM) of Fine Aggregate (FA) = 2.70
Specific Gravity of Coarse Aggregate (CA) = 2.65
Bulk Density of Coarse Aggregate (CA) = 105 pcf
Nominal Maximum Size of Coarse Aggregate = ¾â€
Specific Gravity of Cement = 3.15
