The more we hear or learn from Mr. Nirmalendu Kargupta sir, it seems very very less. Nirmalendu sir is the "Master" Of Admixture technology. From the beginning to the end , everyone has been listening this fantastic presentation for so long. Nobody feel boring / leave. It is possible just because of Nirmalendu sir only. Sir, your guidance / knowledge sharing has always helped us to move forward in life. Look forward to more such valuable session in future...
Great session by Kargupta sir, this session is not only a presentation but has also become a guideline for admixture technology. If any one wants to understand concrete admixture he can see this video. I am going to refer it to all. Great Show presented by Mukund Joshi sir.
Good evening all. First of all would like to thank you all for for your fantastic inspiring comments on my presentation given 19th evening. Further if you have any queries on my presentation can ask me here, I will be giving answers as much as possible. Thanks once again....
OMG! This video was FANTASTIC!! Huge fan here, sir! Every single slide, line, and word was SUPER informative. It blew my mind! This is exactly what I needed. Thank you SO much!! I watched it like 2 or 3 times (took me about 11 hours total!) to make sure I caught everything. Seriously, thank you again! @nirmalendukargupta201 sir and @mukundjoshi sir thank you so much for this wonderful episode
Very very informative video , I will urge every civil engineering professional to watch this video thus they acquire some great knowledge about admixture and it's properties.. such a nice way of explanation sir !
actually i had worked in rmc and right now im working in admix as ct.... your knowledge is admirable and each and every points are so practical....... thank you for your valuable session.
Karguptas visualization on Concrete is something even the best equipment cannot cannot do . His passion for the subject is immense. Hope he brings a new dimension to concrete for improving Durability
Excellent session by Mr. Kargupta. Explained practical aspects related admixture / concrete with current problems faced at site. Thanks Mr. Mukund for such a nice initiative.
It was awesome session, the practical way of demonstration was outstanding.. After all it was out of 35 years of vast experience. Thanks kargupta sahab..
Sir, I have three questions for you: • Some RMC vendors use SNF instead of VMA to reduce slump or increase the viscosity of flowable concrete originally made with PCE admixtures at the plant. While this works, we've also observed a decrease in strength after adding SNF to concrete containing PCE. Could you explain the mechanism behind this strength reduction? • How much water should be used with chemical admixtures when redosing concrete? • How exactly does VMA work? Could you explain its mechanism, such as chain formation or adsorption?
Historical Lecture and explain very soft way to professional for concrete and construction industry.These slides very useful to us in concrete work for future. I request to N.Kargupata sir, please some episode bring for us and continue your experience to all of us . Thanks Sir.
Thanks Ramroop sahab, I am really honored that I got advice from such a person who really a GIANT in construction of Hydro electric power sector in our country. Your advise will make me so motivative that I can share more things in future.
The session was very informative, practical and covered all aspect on concrete and admixture. Expect more such tipe of session in future. It was very well , fantastic and simply explained session.
It was an excellent presentation and knowledge transfer. Covered all most all important concept. Fortunately I had an opportunity to work with Karguta ji.
Thanks Pai sahab, I also so fortunate that I could work with you from Apex. I learnt so many things from a KING (Pai sahab) of a hydel projects. Thanks a lot for inspiring me.
It was really a fantastic session of explaining a vast subject in simplest way and pertaining to the solution of practipal problem faced by a civil construction engineer. I personally learned a lot from this session and hope for more in future from you.
🙏🏻Yes sir , the session was very informative and I got learnt many new things from the session . Please keep conducting such an informative session sir🙏🏻. Thanks for delivering the session Yours sincerely Pranav Mishra
It was a nice presentation. I have got many useful points from your lecture . Please describe the admixture re-doasing in concrete. Any side affect on concrete properties of admixture re-doasing??
Thanks Manoj, You can redose your admixture before you reach initial setting time of concrete but in consultation with your client and to check some plastic as well as hardened properties of concrete undisturbed.
Sayan, thanks for your inspiring comments. At present, CIA is being used separately along with HRWR because its individual dosage is too high like 2 to 4%. But manufacturers are trying to incorporate this CIA along with HRWR in 4th generation PCE molecules. Already we have a admixture combo with HRWR and retarder.
Pipe line choke may occur if your concrete starts sudden slump loss takes place. For example, even if you checked the proper slump say 120 mm just before you allow concrete into the pipe line and after that concrete starts losing slump sharply. In such cases concrete is stuck in the wall of pipe which does not allow concrete to move forward even after a few strokes applied by your pump
