Studies by multiple authors, including Powers, Brownyard and Copeland, indicated that paste had to have a w/c of about 0.40 in order to fill the spaces between cement particles. If we don't have the minimum required water content, our concrete mix will be too stiff to place.

Water cement ratio is nothing but weight of water/weight of cement.

It should be 0.38 as given in M.S Setty book.

As a reference of M.S. Setty book, the answer is 0.38.

Yes, that is approximately 0.40.

It should be 0.45 for thin structure and 0.55 for heavy structure lesser is better.
Aarti said:

Yeah, 0.38 tends to 0.4 so, the correct answer is 0.4.
