The calculation on how to calculate the water cement
ratio is just directly divide the total volume of water
against the volume of the cement (water cement ratio is
equal to the total volume of water over the total volume of
cement)

Answer / khaja

for 1 bag of cement(50
kgs) 27.5 lit of water.
It is calculated from
water cement ratio w/c

Answer / zia

generally water cement ratio is taken inbetween 0.5-0.6
w/c= water/cement
0.5= water/1 bag
0.5= water/50kg
water= 25 litres

Answer / 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.

Answer / rahul

the w/c ratio can be obtained from the empirical graph in the IS 456-2000 code book. the w/c ratio changes on the basis of required compressive strength and workability of concrete

Answer / engg santosh

water cement ration is depending on following factor
1)Grade of concrete
2)Ingradients
3)Required slum
4)location of concrete

A doubly reinforced concrete beam is 25 cm wide and 50cm deep to the centre of tension reinforcement. The centre of compression is steel is 5cm from the compression edge. The areas of the compression and the tension steel are 10.16cm2 and 12.56 cm2 if m=18 and the bending moment at the section is 7,000,000 N-cm. Calculate the stress in concrete and steel.
