Actually I am shocked with disciplines of students, they did not disturbed , initially I was thinking it is just recorded for utube lecture, but student are rocked what a dedication
Before using any superplasticizer, firstly take technical data of superplasticizer bcz different types of superplasticizer is available in the market. Technical data like pH,chloride ion content, %of water reduction
Ex-- suppose u have to take 1000 coins. Due to some constraints, u are eligible for 90%coins only. Total coins = 90/100 x 1000=900 coins for u. Or U can write Total coins =0.9x1000=900
The water content in Table 2 is for angular coarse aggregate and for 25 to 50 mm slump range. For the desired workability (other than 25 to 50 mm slump range), the required water content may be established by trial or an increase by about 3 percent for every additional 25 mm slump (Code - IS 10262 : 2009)

Sir, you said that mass of CA =valume of all ×volume of CA ×sp gr. Of CA,. But dimensionly this is not possible , please reply me i am facing some problem, thankyou sir
Kindly refer the code IS 10262-2009, Formula is already given in the code. U can refer the video for the design steps of mix design th-cam.com/video/m9_VOuRElLs/w-d-xo.html
Yes, You can do but you have to find the properties of ingredients and accordingly design the trail mix and then cast the cube with the proportions obtained.
ye ek example hai .. iski help se tm koie bhi grade ka ratio find kr sakte ho .. Industry me sirf ratio se kaam nhi chlta h ... agar sirf ratio se hi kaam chl jata tu koie IS code kyu padhta .. ya fir code kyu bnaya jata hai ...
A big thanks for uploading this video

Yes. It was a online lecture during the lockdown period.
@@Uzair_khan2890 unbelievable displines more then offline classes, in that panic satuation
Sir , please make a video for M45 bcoz problem is that for superplacizer we can reduce water Max 25 percent only, as I have read ,

@@Uzair_khan2890 thanktou so much sir
thank u sir what is the mix proportion ratio for this ?
Tq sir. ❤
Super sir
Sir aggregate blending % 60-40 se km ya zyada kr sakte hain kya?
Sir , mu question is that why you multiply vy .9 for pumpable concrete when volume should be reduced by 10 percent
Sir, please reply me

Total coins = 90/100 x 1000=900
coins for u.
Or
U can write
Total coins =0.9x1000=900

what percentage we add while in 75mm slump

Without plasticiser kya hum M40 concrete bana skte hai kya
Without plasticizer, M40 concrete easy nhi h ... bcz strength ke sath sath workability bhi dekhna hota h

Are u pursuing B.Tech ?
Can we use this for m40 for cube casting?
Yes, You can do but you have to find the properties of ingredients and accordingly design the trail mix and then cast the cube with the proportions obtained.
For water cement ratio0.30 is 5 heading
Means volume of ca and fa
@@vikasr9495 what you want to say ?
@@Uzair_khan2890 sir for m40 we r doing cement ratio 0.30 and .35 and
Is volume of ca and fa in step 5 changes or remains same as 0.40
A1 and A2 data given rahega kya
Nhi . Ye ek example hai ..
Temperature
Water cement ratio M- 40 ....0.40 maximum hai
Water content me 0.71 calculate nhi smj paya
Maximum cement content nhi diya hai code me
