water cement ratio req for complete hydration is 0.25, but it is not workable, so we can use w/c upto 0.45 to 0.5, more w/c ratio leads to formation of microscopic pores and increases shrinkage.leads to decrease in strength.

taking 0.5 w/c ratio water req for 1 bag of cement is 25 litres.

In the present situation of ban on mining sand from rivers,can we go for formation of earth dam filters viz;Horizantal sand blanket,inclined chimney and filters under rivetment with crushed rock sand of 6mm down size.If so what are the specifications and is there any codal provision for its authentication?
