I appreciate you sir for your hard work ... In Shaa Allah I will do the same as you do for fresh civil engineer and students. I am following you sir for every video
This is a good prove that not all video uploaded in youtube is correct. where on earth is the ratio of concrete class 20/20 has been 1:1.5:3 and concrete class 15 1:2:4.
There are two grading systems, what you choose to work with determine the mix ratios. The C15 ratio is different from the M15. His ratios are correct . The only issue in the video I believe is the amount of water to be, I think it's too much if you use the water/ cement ratio for your calcu
its good i am ask you same qustions 1.by what calculation for any grade of concrete use to water ratio 2.how to use water for m25 &m30 grade of concrete
How did you get the mix ratio of its individual mix of concrete? And how are you sure to get the strength of every grade of concrete mix as you have said in this video.
I have a question in another video where you talked about W/C ratio it would be between 0.4 - 0.6? How did you get 60 Liters for M5 ? Cause if i use 0.4 x 50kg = 20 liters or 0.5 x 50 = 25 Liters or even 0.6 x 50 = 30 Liters How did you get 60 ?
it depends on the design. but according to thumb rules, for PCC ....Grade 7.5 for Footing ..Grade M15 or M20 for coloumn.....Grade M15 or M2o for Beams ,,,,Grade M15 for Slab ,,,,Grade M15 or M10 CDepending on weather its G1, G2 or multi storey structure.
sir plz upload video on foundation of different types likes pier,piles,open,girder.plz upload detalis of their construction with pan and paper that will us in field work.
Kamran Gul your post is correct. The video is incorrect in so many ways, water will be constant for cement....it will not change on the mix....what changers is the water ratio for slump that is required....
Wouldn’t it be easier to calc water per cubic yard according to mix design? How do you know the Precise water is going into the load? “Slump test” 4 inch 5, 6 etc done on site by a resident inspector. Loads are calculated by sacks per yard according to aggregate size. Pea gravel, 3/4 loads, gip, etc etc.
In perfectly water needs 5% from weight cement. More water take stratification in the mix, after dry take micro cracks , if we have sandy ground , the cement milk absorbed in ground lose itself design strenght. We need as little water as possible. water influens on workable mix. And we need to put different additives.
Friends Sorry for Mistake this is not Grade of Cement this is ( Grade of Concrete )
for 40kg cement..what is the ratio?
8
very nice
ok sir

I like how you start with “Salam Alaikum” 👍
Best Engineers with practical approach I have seen from Pakistan in Gulf
I appreciate you sir for your hard work ... In Shaa Allah I will do the same as you do for fresh civil engineer and students. I am following you sir for every video
Mashallah very nice sharing keep it up and stay connected
JazakAllah khair for this video Sir
Love from India ❤️
Amazing sharing
keep in touch
I love you sami bro for ur sake I'm improving my civil knowledge means by basic
Such an lovely explanation 👌👌👌👌👌👌awesome thq so much
Simple, clear and very useful !! Thank you
1.4 million views, congratulations.
Good Working increases Knowledge
Am a civil engineer from uganda army, I have liked the video
V.V NICE EXPLANATION SIR I LIKE YOUR EACH WORDS DEAR SIR
This is a good prove that not all video uploaded in youtube is correct.
where on earth is the ratio of concrete class 20/20 has been 1:1.5:3
and concrete class 15 1:2:4.
Where in the universe is your planet.
So what is the right ratio if he's wrong
I think ratio for grade 15 is 1:3:6
for grade 20 is 1:2:4.
There are two grading systems, what you choose to work with determine the mix ratios. The C15 ratio is different from the M15.
His ratios are correct .
The only issue in the video I believe is the amount of water to be, I think it's too much if you use the water/ cement ratio for your calcu
Thank you so... much. I have lot of confusion in w/c ratio, now it's clear.
Assalamu aleykum ve Rahmetullahi ve barakatuh! It's very important video for civil engineers and builders. Thank you very much and keep going forward!
I gave a like because you started with Salaams
Just want to give you a suggestion. Please make videos on the construction site! That would be great!!
Thank You Sir, aise he video banate raho please
Aaap bohut age jaoyoge
People like short and sweet videos, this is not a short not a sweet
its good i am ask you same qustions
1.by what calculation for any grade of concrete use to water ratio
2.how to use water for m25 &m30 grade of concrete
Water/ cement ratio is depend on grade of concrete
How did you get the mix ratio of its individual mix of concrete? And how are you sure to get the strength of every grade of concrete mix as you have said in this video.
Very Informative.Keep it up
Great
Really enjoy your videos
Nice bro
Alaka der kha. Keep it up
Your explanation is so wonderful
thanks bro you made a great video, pls do more videos for learnings
Best knowledge of cement useing
Nice simple 👌👍
Sami sir, Happy Engineers day to you
Great dear
Good content 👌
Will you please explain, how you have calculated water required for each grade of concrete ?
M15- 0.5 to 0.6 ltrs per 1 kg cement
M20-0.5 ltrs per 1 kg cement
M25-0.45 ltrs per 1 kg cement
@@viswan9092 right
Thank you. I understand what you're getting at.
I have a question in another video where you talked about W/C ratio it would be between 0.4 - 0.6? How did you get 60 Liters for M5 ? Cause if i use 0.4 x 50kg = 20 liters or 0.5 x 50 = 25 Liters or even 0.6 x 50 = 30 Liters How did you get 60 ?
I am also confused. Maybe it has something to do with the sand and aggregate quantity.
your videos are great!
teh dil se sukriya sir ji
Hello! Your new friend from Philippines. Nice vedio tnx for sharing 77likes👍👍👍
😂😂😂 very funny....
Improvisation needed man...😉
Shukriya janaB
Very informational video
Well done 👍
Thanks For Teaching Sir
Whats basic to take the special figur like 60,46,34,etc litre water are required in various or different Concrete gardss
Very nice 👍
nice, great info
Can you explain how to find the quantity of water needed for each grade??
nice vedio i like very much Thank u sir P. tell about M25 and Maximum
Very nice and knowledgeable
How to u decided directly.....water ratio.
How to find the water ratio with explain cleanly
Sir , the number indicates strength in N/cm sqr. OR M/ per cubic cm.
Great ..
Helpful
all of this one just use for experience, if u wanna get true value, you should calculate it and mix it, especially for high strength concrete
explain what is meant by bulking of aggregates? indicate why the extent of bulking of sand depends upon moisture content

Sir, how do you know the exact w/c ratio for Mix grade concrete ? Is there any formula or what ?
IS 456:2000 RCC CODE BOOK
Kindly mention in vedio what farmula use to find how much water use in deffernt garde concrete
How the values of water came...???
I mean how to find how much amount of water required for particular grade of cement...
How do I know what grade of concrete should I use in a certain work? Thank you!
it depends on the design. but according to thumb rules,
for PCC ....Grade 7.5
for Footing ..Grade M15 or M20
for coloumn.....Grade M15 or M2o
for Beams ,,,,Grade M15
for Slab ,,,,Grade M15 or M10

what should be ideal water cement ratio for M50 concrete if 53 grade cement is being used?
What is the criteria to define M7.5 concrete because IS456 defines the characteristic strength of concrete in multiple of 5.....
very good way of telling
Sir plz make videos on preparing DPR
Dear do you think mix design doesn’t depends on contents specifications?
Which you are shown in that video they are constant or we can determine with the help of formula
Sir if a interviewr ask question what is the standard ratio of cracking in concrete ? plz ans batain?
But sir as per as is code
W/c ratio should be in between.
0.45 to 0.60
What is the unit bro?
can you make a video about unite conversion? please....
Mix ratio of sand and aggregate is by volume or weight of cement?
typically its by weight.
on my boq, i have m3 and c15. please explain. thanks
No problems sir....😃nice video
Sir.. how to calculate the quality of water per cement bag(fr grade) ? It's standard or wat?
Sir mortar ko 7 days and 28 ko requred strength निकाल्नुन
simply 50 kg x by 0.6 or 0.5 = 30 litres of water reuired per bag and you wrote grade and didnt show for what purpose is grade used
Kamran Gul your post is correct. The video is incorrect in so many ways, water will be constant for cement....it will not change on the mix....what changers is the water ratio for slump that is required....
Kamran Gul it's the ratio w/c=.6 or .5 so whatever is cement quantity multiply it by.6 or .5
