How to calculate water cement ratio in concrete | Basic Calculation Hindi 

Tutorials Tips from

how you got 0.5

Calculated value from lab

Different grade different value will be there right

Right dear

Bhai mere, maine kya 50-60 bag bata diya kya??

Check uploaded Video and find BBS playlist in playlist

Ok thanks for your feed back

Ha sahi m b confuse tha k aap 35 litre kaise liye hm kaise assume kiye k 35 litre hi Lena h or jab w/c=0.5 To sir w=cx0.5, 50x0.5= 25 liter/kg hoga na sir. Kya m galat solve Kiya plzz sir commt

Bhai mere pani lit mai hai cement kg mai hai dono ka unit factor v same hona chahiye na, isliye cement ko v lit mai convert. Kiya than calculation kiya

Bhai aapka ratio mujhe sahi nahi lag rha hai, aapke block ki strength kitni aa rahi hai??

Thanks

Thanks

Ok thank you jao pogo dekho

Water ki density depend karti hai temp. Par or jab hm design mix ki baat karte hai to water ko 1 litt. =1 kg nahi lete samjhe, equal hota to pani ko v kg mai lete lit mai nahi, kuch diffraction hai scientist sir, kya aishe banoge scientist

@@AmitSahCivil i think you that you did not understand, what i said! i was supporting your logic sir! read my comment again but carefully!

and i never said i know 1kg=1liter! i have just used others' logic to make them understand your tutorial bro! i said "as you know" never said "as we know". and i know that 1 liter and 1kg are not same!

Understood Dear.

thanks

by weight or by volume 2 type se materials quantity, calculate hota hai, isliye data alag alg aata hai

Ok

+Kaleem Khan concrete mix is completly depends upon the structure. If you are talking about residential project, you can take M20. If you want more strength in your project, then you can take M25. Generally people prefer M25, because they can't prepare proper mixture of concrete mix manually.

+Kaleem Khan I will clear your remaining question in my next videos... I already clear your question in my old videos. For more in details, please keep watching and spread your love like this only. ☺

by volume and by weight mai difference aa jayega material mai isliye

Thanks for watching, you can watch more videos related to civil Engineering

YOU ARE DOING GREAT WORK.

Thanks you dear

0.035 ko lit mai convert karene k liye water ki density se multiple kar denge Water ki density hoti hai 1000lit/m^3

I don’t know about Foam, But I think cement have more mass than foam

water, material k moisture par v depend karta hai, so 20-22 ltr. water is ok,

@@AmitSahCivil Moisture alag baat hai par is code 456 ki calculation alag alag kaise ho sakti hai

water cement ration 0.40 to 0.55 tak liya jata hai

Water ratio completely mix design pr depend karta hai.

Sir aap Kaisa liye 30 litres per bag karke...to kuch to rahtana.... jo o grade ke mutabik some litres karke... Sir please o to bi batado

Aap puchna kya chahte hai

Koi v calculation karne k liye unit ko same karna padta hai isliye hm cement ko litter mai convert karenge kyoki water ko hm litter mai lete hai

Ha design mix mai aggregate ka moisture v dekha jata hai,

Where’s cement??? What is 35*2

First you have to convert 1 bag cement into volume of it, than multiple with density of water

admixture ka ratio depend karega aapko strength kya chahiye or kis use k liye concrete banana hai.

waterproofing ka kaam karna hai to concrete mai waterproof daal do

Sir please watch video again

Sab ka diffrent hota hai m25 27L/per bag M20-30L M15-32L M10-34L M7.5- 45L

KOUNSE GRADE KO KOUNSA RATIO USE KARNE KA BATHAE NAI AAP

M10 , M15 ,M20, M25 KO KOUNSE RATIOS USE KARNA AAP BOLE HI NAI BLIND SE HAR AK GRADE KO 0.5 RATIO USE KARNA AAP TITLE AK RAKHTE AUR AK BOLTHE

depend upon design

These both are different bcoz each is different unit itself.

138.89 Ltr

+Jagabandhu Behera bhai or mix design ready hoti hai tab usmai ye chij mentioned ahta hai ki, water ration kitna lena hai, bas ussi se calculate kar lo 1 bag ka fir jitne m cube ka banana rahta hai utne m cube mai kitne bag aayenge usse multiple kar do

Tutorials Tips Sir ek example dekhadigi

+Jagabandhu Behera ji, dekhiye laboratory mai jab hm concrete mix ka testing kare tab ye pata chalti hai, agar aapko basic lena hai to 0.5 se multiple kar do bas

ok sir

M5(1:5:10)=60ltr/bg, M7.5(1:4;8)=45ltr/bg ,M10(1:3:6)=36ltr/bg, M15(1:2;4)=33ltr/bg M20(1:1.5:3)=32ltr/bg, M25(1:1:2)=30ltr/bg

If water or kg is equal than why there are two type of unit use, There are some differences between kg or litter

In the case of water kgs and litres are the same.Please correct it. You are givng false information to the students.Because in case of pure water 1l=1kg.

No sir pure water not 1kg =1lit, its depend upon temperature of water

Agar kg or litter same hota to 2. Unit hoti hi nahi

Volume of 1 bag of cement= Mass of cement /Density of cement =50kg/1440kg/m3=0.03472 m3 Volume of 1 bag of cement=0.003472m3 Now, as we know 1 m3 of water is =1000 Litre (General Rule) 0.03472m3 of water is=1000*.03472=34.72 which is taken as 35 Litre If u r still in confusion let me know.

Bhai tumhari calculation to Out of the box he.... Bhai ye to syllabus ke bahar ka he...😂😂😂😂 Mene to bachpan me pdha tha D=M/V Hota he 50/1440= 0.0347m3 1/0.0347 = 28.81 bags We can say 29 bags...in 1 meter cube

To kya mai 1 cum mai 50 bag bata raha hu?????

Batana kya chah raha hu ye dekho??

Nominal mix mai 0.5 k according pani daal do ya workability k according daal do

Really, than please tell me why we use litter unit???

@@AmitSahCivil what?? 1 litre (volume) weighs 1kg ...Hence the density is 1. How difficult is that to understand?

If both unit (KG and Litter ) are same than why we use both, why not we use kg for water. If you have solid answer for than reply otherwise please dislike video of any thing wrong

@@AmitSahCivil what do mean both units are same ???. Ofcourse they are not same. Litre is a unit for VOLUME. KG is a unit for MASS . Density is MASS / VOLUME. 1 LITRE of water WEIGHS 1 KG.

Litter for volume?

not more than 0.45

.45

Sorry Sir agar aapko Bura laga ho toh.. Lekin jo galat hai wo galat hai Reply ka intezar Rahega..

To bhai 2 method hai to dono hi bataya hua hai video pura to dekho

@@AmitSahCivil lekin method 1 toh pura galat hai..aisa koi method nahi h..method no 2 sahi hai.. Aur 25 ltr water = 25 Kg water (4 degree k hisab se)

M15 mai 0.5 daal sakte ho, but depend upon structure

Mix design par depend karega iska anupat

M-50 mix design me Kya anupat hoga

Uska anupat mix design par depend karega ko strength kya chahiye kis cheej k liye design karte hai wo lap mai hi possible hai

Depending upon design mix

1.5 loose material ke isab se total tumara water kg gumara kam bhaute kam ayega slum pura tight hoga

You can say 1 lit. = 1 kg, but it's depend upon water temp., agar KG or lit. ek hi hai water k liye to 2 unit kyo hai hm water ko kg mai nahi lit. mai hi count karte hai,

@@AmitSahCivil are baba water ka density 1 hi Hota hai 4-degree Celcius pe & temperature change bhi hua to jyada se jyada 1 se 0.97 ho jayega even 70 degrees Celcius pe !!! ab samajhdari se socho ki yadi density thoda kam bhi hua to 25 kg water ka volume jyada se jyada 26 litre ho jayega !!! isliye question ye hai ki tumhare 17.5 litre aur 25 litre wale calculation Mai bahut difference hai.....ab uska justification do aap ?

Use kis mai karna is par depend karega,

nahi bhai ye sab general value, jo normally use hota hai standard aapko design mix se hi pata chalega, normally aap M-20 k liye 0.5 or M -25 k liye 0.45 le sakte hai

Watch this video again

ye ek ratio hai jo practically perform kar k banaya hua hai, ye koi formula se nahi aaya

Sir please aap video ko ek baar aur dekhiye or comment section ko v read kariye, agar phir v na samjh aaye to please let me know. Again i will explain

Volume of 1 bag of cement= Mass of cement /Density of cement =50kg/1440kg/m3=0.03472 m3 Volume of 1 bag of cement=0.003472m3 Now, as we know 1 m3 of water is =1000 Litre (General Rule) 0.03472m3 of water is=1000*.03472=34.72 which is taken as 35 Litre If u r still in confusion let me know.

Video fir se dekhiye

If 1kg is equal to 1 litt, than why these 2 types of measurement.

Your calculation is right but water ko litters mai measurement karte hai na ki KG mai, waise KG or Litters mai jyda koi frk nai hota hai, koi v calculation karte hai to unit same lete hai na ki alag alag

thanks

calculated value hai by lab

@@AmitSahCivil sir in lab w/c ratio is rang from 0.4 to 0.6....u had taken 0.5..y didnot u taken 0.4 nd 0.6

Very good question

But cement ka volume density sab alag alag hota hai na

Water ki density 1000lt/m^3 hota hai or cement ka 1440kg/m^3 hota hai dono mai fark hai

Kon bola 1kg= 1ltr

I think w/c rang from 0.4 to 0.6...

We take 0.5 for m25 ratio

In this case I assumed w/c ratio 0.5 , which generally considered for M25 concrete. Hence 0.5 is taken.

Also It's ratio

water cement ratio should be calculated based on compressive strength. You can refer to ACI STANDARD TABLE.

See calculation, 1litter = is not 1 kg, its different depends upon temperature

Tutorials Tips ok can u explain me more coz in Google it shows what i said

Yes, if both value is equal than why these two different unit made

If you see oil bottle, there mention 930gram for 1 litter, but oil or water density is different

Tutorials Tips ok sir now tell me for 1kg how much liter we required in case of cement

Water ki density se kg ko multiple kar do

Kg

Standard nahi hai, par minimum man sakte hai, fir bhi depending upon mix design

?????

Depend karta hai road kis rype kabhai generally m 20 basic type road mai use karte hai, bas uska sub base layout heavy hota hai,

yes

depend upon moisture of sand, you can use approx 20-21 litter per bag

Calculation

Why 1CM = 10mm

Dear Vikram Singhji, Volume of 1 bag of cement= Mass of cement /Density of cement =50kg/1440kg/m3=0.03472 m3 Volume of 1 bag of cement=0.003472m3 Now, as we know 1 m3 of water is =1000 Litre (General Rule) 0.03472m3 of water is=1000*.03472=34.72 which is taken as 35 Litre If u r still in confusion let me know.

Thanku sir, for your valuable comments.

Thanks Krishna Raj sir..

Concrete ki baat nhi hai water cement ratio ki baat h

Concrete mai 70 degree ka pani daloge kya??? Or jo concrete ka or pani ka lab temperature hota hai wo +- 27 degree par dekhte hai ,4degree par nhi , or jab design mix ki baat karte hai na , volumetric ya weight mix hota, ab aap ka design koun sa hai wo kaise calculate ye aapko dekhta hai,

Kabhi lab mai jaana to ek kaam karna, ek measuring jar lena ismai 1 litt pani dalna or uska weight lena, kuch cheeje clear hongi

@@AmitSahCivil abey bhai kya buddhi hai yaar tumhari !!! wahi to samjha raha hoon yaar ki 4 degree se 70 bhi kar loge to density difference itna nhai hota hai....iska matlab ye hai ki room temperature jo ki 30 degree cesius maan le to density 0.99 ayega !! matlab ki 1 litre paani 0.99 kg ke barabar hoga !! itni si chhoti bat tumhare bheje mai nahi jaa rahi hai :D

@@AmitSahCivil beta aisa hai na humara kam lab mai hi hota hai aur hum research scholar hai aur ye water naap taul karte rehte hai ...thik na ? tum lab mai kaam kiye ho kavi ?

Nahi bhai hmm kaam nhi kiye,

what M35??

M 35 grade

Ratio hai jaise, M25 ,20 hai ussi tarah cement mix banane mai kitna pani mix karna hai usko calculate karne k liye ratio hai
