Which sand (Zone I to Zone IV) requires the highest w/c ratio?

 

[Fakhr Rizvi]

4 zone of sand required the Highest water cement ratio due to increase in surface area water demands also increase which result in cube failures some time.

Zone 1 require more water. Because Fineness and Surface area is more.

 

[Fakhr Rizvi]

No... I am not agree with you.. Because surface area of the 1st zone sand will be less as compare to 4th zone sand. Water requirement of 4 zone sand will be more than 1st zone sand.
