Please make a video on concrete durability test

Sir please make a video on BBS with 100% compliance to IS code and rolling margin

Thanks for the video. Awaited for the long time

3:09 This Batch report from Ultratech RMC 😅

23:36 Sir, What is SR1 and V1?

20:36 could we randomly take the water quantity or as per slump or flow? I thought that we have to reduced the quantity of water by using the admixture or HPCEA. Please Sir clear this 🙏

Sir, could you please share the PPT

Informative...

Sir kindly explain in detail how to make itp and what references we use to make itp on beginners levels sir

Want to learn Mix design of SCC Sir please make a video

Need a video on durability of concrete

Please make a video on scc

Good video sir. Need more videos on self compacting concrete.

Random visits of batching plant should be carried out to cross check the proportions admixture dosage etc

Please Make A Video About Yield Of Concrete In Detail.

Great Explanation... Keep Continue...

Sir, It is very helpful. Every civil engineer needs to know this. If you please give 1 video every day, it will be very useful for me

Sir help us to get the PDF also or launch courses related to QA/QC .

Really Informative... We use gypsum in cement Manufacturing for only increase settings time of cement.

Your approach is positive, respectful, and to the point. Thank you Sir

Sir Please do next video on scc Concrete with 10mm aggregates and best practices

Bhai thoda slow boliye english samajh nhi aari apki

Can you make a video with any kind of material animation as a example, theoretically it's so complected...

Thank You So Much Sir For Makeing This Kind Of Detailed Quality Management Video, Keep Continue For Us...🙏

please give correct reply when samples are 9 0r 10 or13

Please Do more videos on Scc

Sir Please do more videos on self compacting concrete.

Very Knowledgeable, Thank You Sir...

👍🏽

Informative...

দাদা আমি কী আপনার মোবাইল নং পেতে পারি?

Nice know

Well Explained 👍🏻

Sir please do a video of self compacting concrete and how to cast scc cubes.

❤❤❤❤❤❤❤❤good explanation

I think this difference video 1st in youtube...

Sir your thoughts and ideas for Making quality control engineers more knowledgeable. Your efforts are highly appreciated And keep updating sir❤ Please

Sir this acceptable limit (8 percent) is only for natural sand... Can you please mention M Sand acceptance limit as per IS code... Because now a days we are using M Sand only...

Sir do a Trail mix. For scc concrete with 10mm aggregate. Many people are asking this.

Your thoughts and explanation is great sir. Keep updating more 🙌

Good one sir , keep updating more.🎉🎉

Sir wrong target mean strength formula fck+1.65*standard deviation

Sir, if possible please post Concrete yeild test procedure and acceptance criteria...

Nice sir

In your trial proportion you are taking cement 452 kg and Flyash 158 kg ( 452 kg is the total cementitious material na )

What is the cost of Alum formwork

In general, a very good presentation for learners and young engineers to start with except a few points which may have some contradiction. Let me explain one by one. 1) W/C selection - The general curve given in IS 10262, actually based on normal slump concrete and not for SCC. So calculation of w/c ratio from that curve may be not sufficient. It will always be on the higher side than what is actually needed lower value for SCC. For example, with the same w/c ratio of 0.42, one may not have same strength for normal concrete as well as SCC for M30 grade. M30 SCC will always show lesser strength than normal M30 grade concrete because of higher paste content and in other words comparatively with lower A/C ratio. So in this case some margin is to be considered at least (-) 0.02. say the w/c ratio may be considered as 0.40 in place of 0.42. Now the only cement content will be = 190/0.40 = 475 kg in place of 452 kg. 2ndly, while calculating only cement content through w/c ratio, we need to increase total cementitious fines at least 10% of the cement content as per IS 10262, in case of SCM addition like PFA.That means final cementitious content should be at least = 475*1.10= 522 kg. Therefore , final w/c ratio now will be 0.36 (190/522). It is done because of getting equivalent strength in comparison with only cement mix. Blended mix is little prone to Shrinkage cracks and carbonation of concrete.and hence these two effects are compensated with lowering w/c ratio little lower. Considering all above, we can finalize the cementitious content as follows.... Cement = 340 kg PFA = 182 kg Free water = 190 kg W/C = 0.36. 3rdly, W/P ratio by volume (0.85 to 1.10) may be applicable for lower or moderate strength of concrete but certainly not applicable in high strength Concrete like grade M60 and above. In such cases we already observed that this ratio is always less than 0.85. we generally get this ratio in such grades very close to 0.70. Powder content (400 to 600 kg) also may not be applicable in such high grades where we all saw that it ranges between 650 to 700 kg in such grades. So in SCC design IS 10262 alone is not sufficient to follow. It needs some revisions immediately. Thanks Mr. Kamal to deliver a good presentation on SCC in general.

my interview in next week I want to see all of your videos regarding quality control thank you sir for briefing
