Using the following data for an unreinforced PCC Pavement slab: ▪ Design Strength f`c = 4000 psi ▪ Slab thickness = 12” ▪ Standard deviation of f`c obtained from 20 samples = 200 psi ▪ Ignore any exposure requirement ▪ Use air entrained concrete ▪ Fineness Modulus of Fine Aggregates = 2.60 ▪ Maximum aggregate Size = 2” and nominal maximum aggregate size 1 ½ “ ▪ Bulk oven-dry specific gravity of Coarse Aggregate = 2.60 ▪ Oven-dry rodded density of coarse aggregate = 125 pcf Find the following: a) Required compressive strength b) Water-Cement Ratio c) Coarse aggregate amount (lb/yd3 ) d) If the w/c ratio is 10% reduced, will the quantity of coarse aggregate increase, decrease or remain the same? Explain your answer.

Question
Using the following data for an unreinforced PCC Pavement slab:
▪ Design Strength f`c = 4000 psi
▪ Slab thickness = 12”
▪ Standard deviation of f`c obtained from 20 samples = 200 psi
▪ Ignore any exposure requirement
▪ Use air entrained concrete
▪ Fineness Modulus of Fine Aggregates = 2.60
▪ Maximum aggregate Size = 2” and nominal maximum aggregate size 1 ½ “
▪ Bulk oven-dry specific gravity of Coarse Aggregate = 2.60
▪ Oven-dry rodded density of coarse aggregate = 125 pcf
Find the following:
a) Required compressive strength
b) Water-Cement Ratio
c) Coarse aggregate amount (lb/yd3
)
d) If the w/c ratio is 10% reduced, will the quantity of coarse aggregate increase, decrease
or remain the same? Explain your answer.
