If any interview you say M20 has 403 kg Cement definitely you will out. Practically M20 has 250 to 280 kg as per design mix. Nice video #factualcivilengineering
Hey come-on guys...it can't be 280 kgs..min is 300 kgs..other wise u can't get the strength which u want...if u r using 250 kgs of cement for m20..maybe u did govt.contracts..if u want a quality work 6 bags of cement must
@@prasadpdrc7323 thanks for your comment, however in govt. / cpwd contracts min. 300kg allowed for M25 grade concrete because according to IS 456 standard concete start from M25. I hope you understand.
As you explained above Same amount of water will add for 1 m3 in concrete miller I didn't see in practical, they add more water randomly Plz comment on this sir
You are showing here for a 50 kg bag of cement. How about for a 40 kg bag of cement which is used commonly from other countries. Can you show video about the the mixtures for M5 to M20. Thanks..
So the correct water/cement average ratio should be 50% NOT 0.5% (ref Didar H), otherwise it would be 250ml water per 50kg bag cement !!!!!??? Civil Engineers ... please confirm & correct !! Otherwise, thanks for clarifying, it makes it easier to work out by volume for small DIY jobs !!
1bag of cement =50/1440=0.03472m3 We can say 1bag cement =35 Liter W/C = 0.5 W = C*O.5 W = 35*0.5 = 17.5 Liter Water / Bag. ۔ ۔ You did wrong sir W = 50*0.5 = 25 kg / Bag Liter
Brother, it is nice that you want to help and explain, but saying "kg" instead of "kilogram(s)" is not helping. Also, get your math done right before explaining to others: a ratio is not expressed in percents although they're closely related. You should have said "the water to cement WEIGHT ratio is 0.5, or 0.5:1" or "the water is 48 to 60% of the cement weight in the mix" or "we add 0.5 liters of water to every kilogram of cement, or 25 liters to a 50-kilogram bag of cement"!
You talk differently than writing. You are saying water ratio is between 0.4 to 0.6% and take a number 0.5 which should then be 0.5%. So on one hand you talk percentage and then use a number forgetting about percent which should the number divided by 100. Actually a ratio is never in percentage but a number. So please first you correct yourself, and use proper terminology. Thanks
#Dear previous lecture you told us thats #30litres is needed for #m20 . 32L for M15... Nd Now You saying thats #200Litres for #M20 #Can YoU #explain it ?😱 Waiting 4 ur #Answr
As for my point of view of his lecture, he said that 30 litres of water is equal to the ratio of M20 grade with a mix ratio of (1:1.5:3), while 200 litres of water is equal to 1 cubic metre of M20 grade with a mix ratio of (1:1.5:3) 😁

This is very good and usefull. Easily understand. Thanks.
Sir !!Thanks .
love from india👍
Good work and I understand that topic easily
So thanks
I always enjoy your lecture. Thanks bro
Which grade best quality
You mean by weight of cement his density?
shall we use same formula for different grades of concrete??
0.5%!!!
Right is 50% of total cement weight cosider as water weight.
Like=50kg cemet X 50%=25 litres water.
Right bro
exellent bro....
Water cement ratio vary in PCC& RCC also as per grade of concrete M15 M 20 M 25.
thankyou for this information and nice explanation
perfect lecture Ing. Sami keep it up sir.
Samy ur great man.thankz
Sir Thanks For Teaching 👍🏻✌🏻
Ur effort is appreciated sir.thanks.
Excellent sir
great video. very useful information sir.
Thank you good explaination
If any interview you say M20 has 403 kg Cement definitely you will out. Practically M20 has 250 to 280 kg as per design mix. Nice video #factualcivilengineering
Haha OK bro
Hey come-on guys...it can't be 280 kgs..min is 300 kgs..other wise u can't get the strength which u want...if u r using 250 kgs of cement for m20..maybe u did govt.contracts..if u want a quality work 6 bags of cement must
@@prasadpdrc7323 thanks for your comment, however in govt. / cpwd contracts min. 300kg allowed for M25 grade concrete because according to IS 456 standard concete start from M25. I hope you understand.
I think volume of mix is 1.57
The ratio of cement, sand, and crushed stone (1 : 1.5 : 3) is by volume or by weight?
Water cement ratio .42 to .6 can always we take all grade or only m20 mix
Expertise your knowledge of civil engineering here!
Its help thnku
Sr 1:4:8 ka rtio h tb kitna water milana hoga concrete m??
Very nice explanation.clear to see and listen and easy to understand. Please upload mix design of concrete as per Indian code.
so nice sir
Thank you sir for your excellent explaination and your deeply contrabution knowledge for us
Watch more my dear here
Sir how to calculate fiber for concrete
How much is 0.5%water
M15 grade, W/C-0.6 & unit weight of concrete is 2400kg/m3 then water required??
How you. Determine the water ratio of 0.50%. pl explain.
m25& m30
assume water value ?
Waooo.. great work sir, keep going.
Congrats!!😊
Sir letter to letter manteply ya letter to kg
Sir how much cement sand and aggregate quantity is required in 1000 sqft area 12 no. Of column 8', beam 2' height and slab all having 5 " thickness
Please I need a solution for using 150mmx150mmx150mm cube not 1m³
For which concrete we use 0.42 to 0.6?
Muhammad Rizwankhan Water Cement Ratio With Design Mix Calculation ruclips.net/video/u_edb7pp1IA/видео.html
this is so great! :)
Really ???percentage???? if you are assuming 0.5 (for 0.42-0.6) than its 50% (not 0.5%, it'll be way less)
As you explained above
Same amount of water will add for 1 m3 in concrete miller
I didn't see in practical, they add more water randomly
Plz comment on this sir
For any grade of concrete, M20, M25, M15..... For all of them w/c ratio is( 0.5*cement) .... Is it?
Yes.
very nice
I got 17.5 litres per bag water.
Why did u say ratio of w/c is arange, while u fixed strength to 20 mpa?
sir
jese m5 = 1:4:8 hai to
1 bag = 50kg hota hai
cement 1 beg
send 4 beg
agg = 8 beg
yese hi ho ga
TO USES THE SAME CEMENT RATIO FOR ALL GRADE CONCRETE?
Watch more here
Sir aisa koi tareeka Nahi h kya jisme hum water cement ratio calculate Kar sakte h??
But 1 bag cement is = 35 litre so why didn't you multiply by 35 .....
And why 50 kg
200 ltrs for how many bags sir, kindly reply sir
venkataraman R 200 litre water for 8 bags
Awesome bro
sir also upload quantity of cement bags required for a structure
Brother you are mixing the liters and kilogram....kindly take a look at this....in liters there should be 140 litres
Volume=mass/density
Volume=200 Kg/1000 kg/m^3
Volume=0.2 m^3 *1000 Liters
Volume=200 Liters
Therefore 1 kg=1 liters
How about converting cement to m^3 then to ltrs and then multiply with 0.5
Density= mass/ Volume
By using this formula
Density of cement 1440 kg/m^3
& Weight of C beg =50 kg.
Just put the given dsta in formula it's easy ❤️💞
But there is remain aggregate, and sand in concrete, what about these?
Hello sir thank you so much sir you explained the use water ratio very well thank you so much sir its kavinder gautam from india...🤍👏
thank u sir for this video lecture 👌👌 nice video making
Thanks
Thanks Sir
Dear sir please upload complet mix design if possible?
nice
THANK YOU SIR......
Mashallah Sir Ji
Jzakllah Kher Hbibi
You are showing here for a 50 kg bag of cement. How about for a 40 kg bag of cement which is used commonly from other countries. Can you show video about the the mixtures for M5 to M20. Thanks..
samy sir i really like your vidios and infact i am gaining knowledge. but this is not good so many ads in a video
Sir plz upload videos about roads estimation nd slop etc...
Yes dear
THANKS
Nice one
Thanks
So the correct water/cement average ratio should be 50% NOT 0.5% (ref Didar H), otherwise it would be 250ml water per 50kg bag cement !!!!!??? Civil Engineers ... please confirm & correct !! Otherwise, thanks for clarifying, it makes it easier to work out by volume for small DIY jobs !!
Its 50%, and it depends the slump what you need
1bag of cement =50/1440=0.03472m3
We can say 1bag cement =35 Liter
W/C = 0.5
W = C*O.5
W = 35*0.5 = 17.5 Liter Water / Bag.
۔
۔
You did wrong sir
W = 50*0.5 = 25 kg / Bag Liter
can I do this for different grades and for 40kg cement?
Are u making maps also?
Must reply plz
m20=1:2:3.water=.?
Very very nice explain in this video thank you
This calculation is wrong... 17.5lit water need for 1beg cement. Please check
Dry volume= 1× 1.54
M20 means
M for mix. 20 is compresive strength of concrete
Super
Thank you bro
5℅ * 400 = 200 litre water. Easy
Sir the ratio is 0.42 to 0.6 but why assume 0.5 only
It depends on the slump what you need
Tq sir
Asalmwale kum k sath namaskar bhi bol diya kro
Sir... Only 0.42 to 0.6 , not percent
M25,M15
can i ask numerical related to this
please provide contact detail
i want to ask numerical , please help
voilene of cement willl be 0.0354m3 :D
what about design of circular beam
How 25kg= 25litre
Sorry sir it's not 0.42 to 0.6% it is 0.4 to 0.6 %
water is about 0.25kg not 25
I'm sorry.. where did you get the factor "1.54"?
Brother, it is nice that you want to help and explain, but saying "kg" instead of "kilogram(s)" is not helping. Also, get your math done right before explaining to others: a ratio is not expressed in percents although they're closely related.
You should have said "the water to cement WEIGHT ratio is 0.5, or 0.5:1" or "the water is 48 to 60% of the cement weight in the mix" or "we add 0.5 liters of water to every kilogram of cement, or 25 liters to a 50-kilogram bag of cement"!
"%" ????
See here
Why use 1.54 , someone use 1.57
The value of 400 i didnt understand
Please explain the concept of design mix. Where less cement is used to obtain high compressive strength
Deepak Saini ruclips.net/video/u_edb7pp1IA/видео.html here you get your concept design mix process of water cement ratio & cement calculation
👍
U said Wrong calculate
