In this tutorial i have shown you how to calculate the quantity of water required for any concrete mix.
Before starting the procedure we must know what is water cement ratio?
W/c ratio is defined as the ratio of weight of water to the weight of cement required for a concrete mix.
As we know concrete contains ingredients such as cement sand fine aggregates and coarse aggregates. We need correct proportion of admixture to combine these materials in order to achieve a desired compressive strength
So water plays an important role in initiating the chemical reaction between water & cement which is known as hydration. This produces heat and is called as heat of hydration.
Adding too much water will affect the strength of concrete as it will cause segregation of the sand and aggregate components of concrete.
Also the excessive water which is not consumed by hydration reaction may leave the concrete as it hardens leaving behind pores. That will reduce the final strength of concrete.
Hence an optimum water cement ratio is required to achieve a desirable compressive strength.
As per IS 456 2000 water cement ratio varies between 0.4 to 0.6 depending upon exposure conditions and the type of concrete mix.
I have extracted a table from IS456 2000 to give you a clear explanation about various water cement ratios for different concrete mixtures under different exposures.

Thq so much sir plz do more videos like this ..🙏🙏🙏

[@jimmyqing]

Great video.. thank you..

[@kifayatdar983]

Thank Bro Keep it up ❤️

[@negashmelaku2955]

Nice

[@ramdeepkumar7616]

Good

[@bhuvaneswaran2562]

Thank you so much

[@rubankumard5572]

@Civil Tutor Sir, Thanks for the Video. I have one doubt about Volume to weight conversion. The doubt is once we calculate the Cement volume on m3 then why we can calculate the number of bags instead of m3 to Kg conversion

[@nizamali7027]

Good video

[@CivilTutor]

Glad you enjoyed

[@asgharbadshah5592]

Pls make a video on Concrete Compressive strength and Cylinder Strength and give ACI reference as well with IS references.

Sir ki 277 litre sahi answer a?

[@kyawkyawkyaw5948]

😇

[@peterpan8627]

277 litres of water sounds a lot of water.
