HELLO CIVIL ENGINEERS,
WELCOME TO WORLD OF CIVILGURUJI....
Fresher Engineer Should Know Reality of Industry & Demand for Skills before INVESTING Money
In this video Er. Kishan Ojha, Corporate Trainer of Civil Guruji explaining about M25 Concrete Grade | How to Calculate Cement, Sand, and Aggregate for Mix Design
Concrete is a composite mixture which consists of Cement, Sand and Aggregate. Concrete mix design is the procedure for finding the right quantities of these materials to achieve the desired strength. Accurate concrete mix design makes concrete construction economical. Large constructions such as Bridges, dams requires huge amount of concrete, using the right quantity of constituents make the structure economical. In order to calculate or find the right amount of cement, sand and aggregate required in 1m3 of concrete; you need to know about different grades of concrete.
M25 Concrete Grade | How to Calculate Cement, Sand, and Aggregate for Mix Design || By CivilGuruji
As per IS456:2000, Different grades of concrete are classified into M5, M7.5, M10, M15 etc., whereas M stands for Mix and the number behind M stands for Characteristic Compressive strength of the concrete in N/mm2 @28 days when checked with 15cm×15cm×15cm cube in direct compression test.
M25 Concrete Grade | How to Calculate Cement, Sand, and Aggregate for Mix Design || By CivilGuruji
Concrete Mix design of M5, M7.5, M10, M15, M20, M25, M30 and higher grades of concrete is calculated as below:
The procedure for finding the different grades of concrete mixes are same. The below mentioned method can be applied to any grade of concrete by changing the values. To make ease in understanding we are finding the Concrete mix design of M20 grade concrete.
M25 Concrete Grade | How to Calculate Cement, Sand, and Aggregate for Mix Design || By CivilGuruji
The Concrete mix ratio for M20 grade of concrete is 1:1.5:3 that mean 1 part of cement, 1.5 part of sand (fine aggregate) and 3 parts of aggregate (crushed stone) in volume and then batched for mixing.
Nominal Mix is generally adopted for small scale constructions. In this type of mix, the mix ratios and concrete constituent proportions are prefixed and specified. Eg: M20(1:1.5:3); the quantity of cement, sand and aggregate is batched in volume as per the fixed ratio 1:1.5:3. M25 grade, the concrete proportions are called as Nominal mix concrete.

Thank you sir I am from Pak. We look your vedio is so Great teaching
Masha Allah. Useful video. Thnxx
Thank you for acknowledging our efforts, Civil Guruji will continue providing content for Civil Engineers. Stay curious, stay supportive, and keep learning.
Good knowledge sir your thanks
Good bro. Appricate you

Will not use density for sand and aggregate in formula as we use it for cement?
Purani yaade taza ho gyi sir..dil khush ho jata h apse sikh k😄🙏
bhai sand,aggrigate ka dencity kyo nhi nikale
Good teaching
Sir aur tokri/tashla mai cement ,sand,aggregate ka quantity kaise btaya jata hai site mai labours ko..
Tokri ya tashla ki jagan agar pharma use karskte ho to karo other wise ek baar material weight karlo phir bata do design ke according
Cement: 7.10 bags
Sand: 29.62 Cft
Water:. 177.5 Litres,
1. Cement :- 7.1/ cum
2. Sand ( Fine Aggregate):- 15.88/ cum
3. Aggregate( Coarse ) :- 29.30/cum
4. Water :- 177.5 LTR
7 bag cement.
16.03 cubic feet fine Aggregate (sand).
29.63 course Aggregate.
175 kg water 💧
mix design ko banane ke liye.
Sir why we will not use density of sand and aggregate while calculating but cement density used?
Sand & aggregate ko kaise kg me nikalte hai voh batana sirji.
Density se multiply kar do Bhai kg me nikal jayega
Multiply quantity by unit weight of materials
No of cement bagse 12.149
Sand 16.0343 cumf
Agg. 29.628cumf
Water ratio 303.725kg
Cement bag =7.10 bag
Sand =16.03cumfeet
Aggregate=29.62cumfeet
Water =177.5 leter
Cement-7.107 bag
Sand-16.034cft
Aggregate-29.628cft
Water-177.675 ltrs.
Ser nice work

Quantity of aggregate in cft 29.6287.
Mai cheap dumbells banane ki koshish kar rha hu, to 1 kg sand, 1 kg cement aur 2 kg rowdi hogi, shi h na??
Cement 7.11 bag, sand 16.07 cubic feet, aggregate 29.65 cubic feet, water 177.75 kg
how can i find difference cost of material in estimation.

Can anyone clear this point.....if thay alerdy taken 186ltrs water for mix..and also added voids percentage of agrregate...tha y we calculate 54% extra for voids.....they already taken voids percentage like 20mm aggregate 6% .....any one have guts to answer this
I wonder what you are teaching. Use IS 10262: 2019 and show proper calculations to all the students. Also, while showing minimum grade of concrete don't forget to mention IS clause.
sir, what is the acceptable qty of fly ash that can be user per mcube of concrete? We recently bought cement for slab from RMC and they used 1571 kgs of cement, 676 kgs of fly ash, 5770 kgs sand, 7627 kgs of aggregate and 1179 ltrs of water for 7 mcube.. can you please check if this is acceptable and if we do manual mixing at site, are these same proportions maintained? because i've seen contractors say that 1:1:2 can't be used in manual mixing so they suggest some weird ratios like 2/5/6 or 3/4/5 and so on..
7.10 bag
Cement= 7.10 begs
Sand = 16 cft
Aggregate = 29.62 cft

Cement- 7.11 bags
Sand-16.03 cum ft
Aggregate- 29.63 cum ft
Water- 177.75 litres
Kaise
😎😎
During calculation, you used cement unit weight but not in sand and aggregate.why....? Pls explain.thx.
M.Shafqat Munir
Lahore,Pakistan
Kyunki cement ko bag mai nikna tha aur sand aur aggregate ko cum ya CFT mai
pls tell who to find mixes design
Cube ka dim 150mm lena h ?
sir aap ne aggregate ka quantity nikalne kr liye uske density se multiply nhi kiya
water 177.5 lt
How to calculate with detail sir ..
Very helpful video sir 👍🙏
Hii sir mere papa builder hai air mujhe civil engineer banna hai to muze site konsa knowledge hona jaruri hai
Aap civil engineer banjao phir site join karo construction process and activities seekho kaun kaun si raheti hai site pe kitne din Mai hoti hai phir jab seekh jao to Paper work seekho ache se phir lagg jao pappa ke sath
Sir, at the last, how did you taken kg being equal to litre? Explain please
1 gm of water is equal to 1 ml of water
1 litre of water equals 1 kilogram
Gud morning sir
Sand and aggregate ka density multiple nahi hoga sir
Sabhi density multiply hoga
7.10 bags
Good morning
Cement 7.11 bags (we will take 8 bags)
Sand: 13.42 cubic ft
Aggregate : 29.63 cubic ft
Water 200 litre
Sand in cubic metres comes 0.45
And after converting it into cubic feet by multiplying it to 35.31 the quantity we get is 16.03 CFT
And water is 177.5 litres accurately
1200sq feet kitna ceement giti lgega
Sir Comment reply please
16 cft sand
This is for 1 cubic meter Concrete, what if, if we have 3000 cubic meter Concrete how we can adjust the mentioned Quantity.?
Multiply with 3000

I wonder what you are teaching..... Have you ever seen Is code for Mix design , if not please see first.....
Because all you are teaching only on your method but there is some thumb rule for calculating of mix design that is showing in Is code .... Don't mislead students
Density???
Dry coefficient is 1.33 na sir ???
No 1.54
Sir while finding quantities for slab how to find and add quantity for beam
Cement 7.38bags
Sand 17.13 cut
Aggregate 31.63cuft
Water 184.5 lit.
Dear Sir it is Correct .Please mention
Find it separtely by AutoCAD drawing first find for beam and column then for slab then add them you will quantity of slab

This is poor/Good
Sir give you answer so please help me sir 😢😢😢😢

What is the meaning of 5/8 size of aggregate?
Bhai ye to M20 se bhi niche ja rha

Dear civil guruji please dont bother to answer
Density of cement = 1440 kg/m3
specific gravity of cement= 3.15.
But, speicific gravity of cement= density of cement/density of water.
So why the above values didnt satisfy the relationship betn sp.gravity and density.?
Cement : 7.11 bag
Sand : 16.03 cum . feet
Aggregate : 29.62 cum . feet
Water Ratio : 177.75 litres
aa gya sir
Okey.
Cement =17.76
Sand=8.07cum
Cuft=284.9
Aggregate =10.47cum
Cuft=369.9
Water=444kg
