Least surface area requires less water.

Adnan said:   9 years ago
The Right answer is B.

Apcivilian said:   9 years ago
Yes it's B.

Mahi said:   9 years ago
How coarse aggregates surface area is less?

Fine aggregates surface area is less.

Least surface area required more water.

Nirmal sharma said:   8 years ago
The right answer is B.

Sanam said:   7 years ago
The Given answer is correct.

It says "least amount of water which gives greatest surface area for given amount of cement and aggregates.

Talib said:   7 years ago
Answer is correct as it's given that for a given workability.

Vivek mishra said:   7 years ago
Given Answer is correct because finely grinded cement required less water and it cover more area.

Garry said:   6 years ago
For a given workability means it is fixed.

If we want same amount of easyness with that concrete paste then surface area should be low.

As we will increase fineness more area will absorb water and friction increases so can't give the same level of easyness means workability.

@Sanam.

It Means as grade increase water required for greater surface area decreases.
