They begin talking about it at 3:15

Great video Dr. Have some questions after watching your video. 1. Which one is the best silica to be used in concrete technology /readymix plants ? Is it silica fume (the by product) or the manufactured silica? 2. I have noted silica fume having grey shade (blackish grey/like cement) whereas the manufactured silica is white or half white and sometimes in other different light color shade. Does the color difference make any impact in the final product and raise question from customer in terms of product standard? 3. Which one of them Is ideal for results over longer period of time when used. 4. Any idea which kind of silica does the concrete technology market demand ? Or does it vary region to region?

Love your videos and the passion for educating people... BUT.. after you explain it to me and I finally know what product I need to use (Colloidal Silica), where do I get it? I really think you should put in your description where to purchase because we trust your curation of where to buy these products. I have purchased Colloidal Silica on amazon twice and it was Fumed Silica :(. HELP

[@eduardodeluna3123]

You could use Levasil colloidal silica from Nouryon.

Hello . Is there any difference between collodial silica and nano silica powder?

[@IntelligentConcrete]

HamidReza R I’ll be answering this next week.

[@hamidrezar1040]

@@IntelligentConcrete My pleasure

[@k.sivatejachopperla9379]

There are a few instances where large particles of silica fume or agglomerated silica fume particles act as alkali-reactive particles and can cause microcracks around them. I bet we won't see that problem with colloidal silica.

[@IntelligentConcrete]

There are some instances where too much of a very particle can cause problems.

Hi Could you shoot a video about making water-based matt varnish with Micronized Silica?

[@IntelligentConcrete]

Will do.

[@gunteoman7308]

Thank you

[@matthewgawelko996]

What’s the benefit to using both?

[@IntelligentConcrete]

Howdy Matt!!! I hope all is well. Shoot me message on LinkedIn for catch up when time permits. Using both, in balance, can lead a denser mix similar to when combining different gradations of aggregate. The difference being the pozzolanic reaction from both the nano and micro silica.

[@elkhalilelkhadir3376]

Awesome and deep explanation !! I like deep explanation especially when you talk about Mechanisms and chemical interaction ! Thanks a bunch Dr Belkowitz !!

[@IntelligentConcrete]

elkhadir elkhalil no problem!!!

[@Triplet_Mrstreet]

How would I go about making my own ceramic coating

[@IntelligentConcrete]

Triplet Official we’ll be running a video on this within the next couple of weeks.

[@Triplet_Mrstreet]

I’ll be keep ling watch for your video thanks

[@VenturiLife]

Don't get that stuff in your lungs.

[@coeniebre]

What about sodium sodium silicate liquid?

[@IntelligentConcrete]

Coenie Breytenbach will be diving into this week. Thanks for question.

[@kevbeer1]

You are a quite animated fellow. One of many frustrations I have had with youtube education leading to my gfrc pinhole fill. But you do you.

[@IntelligentConcrete]

Thanks for the feedback Kevin. Did you have a question about GFRC?

[@kevbeer1]

Nope thanks for vid!

[@2506Larry]

It would be nice if you actually respond to inquiries!

[@IntelligentConcrete]

Thanks for your input Larry.

[@astalavisitor]

¹.Too long intro. ². No pictures coupled with too much talking. *Its boring* I like your info, i respect your effort but unless your videos become more digestible, you will be stuck with 5k subscribers

[@IntelligentConcrete]

Agreed Monty. We are working on shifting our production team. Thanks for the feedback.

[@GrooveyTuesday]

Yeah that was hard to get through. Lots of fluff and weird hand stuff.

[@2506Larry]

I am told that colloidal silica's are a 1 & done! And Solanes are the better choice.

[@IntelligentConcrete]

Thanks for your response Larry. I don’t understand the “1 &done” comment. Please give some more detail or explain the comment. Thank you.

[@allahrakhaallahrakha9458]

Plesse contect me

[@IntelligentConcrete]

How?

[@हरिःव्योम]

So you guys really didn't mix it with concrete.. duh!

[@IntelligentConcrete]

Was that a question Seth?
