Answer. Should be zone 4. Because zone 4 is finer than other zone so, It's surface area is more. And More surface area required More w/c ratio.

Zone iv have more void than zone I. so more void requires more cement and water so answer should be D.

Aswer should be zone 4. Zoning start from coarser to finer. So, zone 4 is the finer one. For finer sand surface area is more so more high water cement ratio.

In w/c, Water is In numerator so sand requiring more water will have more w/c ratio.

Yes, right @Sultan.

I think Zone 4 because fine sand having large surface area so w/c ratio will more require to lubricant.

Is it because of surface area?

Dinesh sharma said:   8 years ago
Correct answer zone-4, because zone - 4 more surface area compare to zone -1.

Sumit said:   8 years ago
I think option a) is correct, because same volume coarse sand required more water.

Garry said:   8 years ago
D is the correct answer.
