Answer Posted / abdul
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.
