In this video, we are discussing the grades of concrete how can we use different grades
in PCC(Plain Cement Concrete) and in RCC(Reinforce Cement Concrete).
Grade of Concrete Proportion
M5 1:5:10
M7.5 1:4:8
M10 1:3:6
M15 1:2:4
M20 1:1.5:3
M25 1:1:2
In which (M5 - 1:5:10)
"M" is for Mix
"5" is for Compressive Strength of Concrete (in N/mm2)
"1" is for Cement
"5" is for Sand
"10" is for Aggregate
Why do we always use 28 days Compressive Strength in Concrete (cube) and not 20 or 40 days?
We use 28 days Compressive Strength because it gives us total strength in 28 days.
For Example: Here, we can use at least three concrete cubes (150 x 150 x 150)mm are cast for each mix at 27 degrees Celcius
and they are tested in a laboratory at 28 days. Its mean strength is calculated at 28 days and that is the strength of concrete
for that particular mix.
- In 1 day it gives 16% Compressive Strength
- In 3 days it gives 40% Compressive Strength
- In 7 days it gives 65% Compressive Strength
- In 14 days it gives 90% Compressive Strength
- In 28 days it gives 99% Compressive Strength

Awesome video, really helpful!! One quick question- How much is the difference in cost per square foot between RCC Grade M20 and M25?
Tq sir ache se samjhane ke liy
Nicely explained
Very clear explanation thank you
Tq 🥰 sir give for valuable tips ❤❤❤❤
Sir IS 16415:2015 COMPOSITE CEMENT KA FULL EXPLAIN KA VIDEO BANAYE
Thanks sir
As per is code 454 the nominal mix is mentioned upto M 20. Not for M25
Apko fir se rivision krne ki jarurt hai
Badhiya information
dear Sir, ... "10" is for Aggregate ... Kya? what? ... kya ye khadi ? hai ? kya hai? SERIOUS ? 🙏
Characteristic compressive strength
Good information
Thank u sir very much
👏👏👏👏
Hello Good morning
Ratio by volume hai ya by weight
Canal ki lining me kon sa grade use hota h.
Sir ye age(days) kon se IS Code mein aur kon si table mein hai
M-25G compressive strength 28 Din Mein Kitni strength honi chahie (4fck)
Hello sir
सर एम 30ग्रेड और एम 60ग्रेड कहां युज होता हैं माई वन टेक्नोलॉजी में बताएं
Column & shear mai use krte h
M30 &M35 ko beam m use kr skte h
👍
Sir M5 mai 1:5:10
AndM7.5mai 1:4:8
Yaha 5and 7.5 compressive strength hai lakin kaise aaya
m50 design me sir 450 se jada cement use kr sakte hai ki nai
Nahi kar sakte , combine me flyash use kar sakte he
Sand bhi to aggregate hi h
Sir send kya hota hai
Bro take good thing.there are lots to learn
Sand - बालू
Tu bhai mistry h ya engineer
Agar vo engineer hota to kya send ya sand pata nahi rehta kya 😂
🫡🫡
sand: 1200 kg/cu.m.
metal: 1300 kg/cu.m.
Density of materials: Is it ok???
Thankyou sir
