The fact that the non-autoclaved blocks have small fibres in them means that they're not comparing apples with apples when performing the strength tests. The non-autoclaved block also looks like it's core contained moisture during the heat conductivity test, which could have impacted the temperature reading.
Video title should say autoclaved aerated concrete (AAC) vs fiber reinforced aerated concrete (FRAC). Of course the FRAC is going to be stronger because of its reinforcing fibers. They allow the concrete block to handle internal tensile stresses far better than AAC.
then you suggest fiber in AAC would be stronger? I used fiber in my cement and was shocked to see all the "hairs". I thougt it was fiberglass until the mason used his lighter to burn off the fuzz. Just pieces of Polypropolyene rope would do the same? I paid $5 USD for 1lb of the fiber in Texas. Should of cut up a rope instead.
you forgot an important thing to mention. what is the density of each? and what conductivity does the lambda have? the non-autoclaved its 50% heavy than autoclaved.
I think they use aome type of poly fiber mix with cement and sand In india a fiber by reliance company is used on a ratio of 100 grams per 50 kg of cement
These tests don't include long term durability. If aerated concrete was superior to AAC why would companies include the expensive Autoclaving technique making their product more expensive? and why wouldn't another company produce the less expensive Aerated Concrete and put them all out of business? In affective propaganda the devil is not in i what you are told, but what you are not told!!!
water absorption is normal since autoclave means water is transformed in steam and so one for 16 hours!!! that s mean a stress applied to fast cure for fast production .natural cure maybe add a liitle under certain conditions !but is not economical for factories ! since the blocks are still wet !that s way they embed in plastic de AAC Blocks !plastic capisi ?
Not very scientific, IMHO. What was the original weight of the 100mm cube to start? I guess I could do the math.... what about freezing a wet block.... my non-frostproof tile is just popping off this winter.
I’m worried about Spalling from freeze thaw as well. I believe that a high quality polymer modified stucco and or sealing agents would keep the problem to a minimum
Your heat conductivity test appears to be bull shit! Your moving your torch around a large circle on the non-autoclave one, and you are keeping your torch in one spot on the autoclave! Your temperatures are off by about 1 degree. I'm guessing they would be much much higher on the non-autoclave if you kept that torch in one spot. Your going to get thermal bridging with any type of concrete reinforcing material added vers not having any! Common sense and anyone that ever worked with concrete would already know this!
So are companies that sell autoclaves aerated concrete just adding processing in order to justify added cost? Is it because non-autoclaved concrete does not have the inflated profit margin the companies want? That's wrong!!!
darthvader5300 Actually I've been thinking just that Darth. OPC probably isn't the best option for aerated concrete. But cost is the main issue. OPC is a lot cheaper.
No... In Japan , Indonesia, Philippines they use hollow blocks... inserting steel rods... which makes the structure more durable & wall doesnt fall off...
In reality, these panels are reinforced with vertical rebars from beam to beam, so there's less chance of falling over. Besides, you connect them with mortars. It's not as strong as brick wall.
the video is bias i think..it tries to exzezerate point of action against the other..eg..while droping aac, it was lifted a bit, that increases gravity & fall. Hence, impacted quicker. secondly, while firing the layer of aac, it aimed at only one point that induce more heat, while non aac it was always motion in circulation, impecting less on heat
Yes CLC block is stronger than AAC block. Although CLC block takes much time for curing it is more stronger than AAC block. I am an engineer who has worked in both these plants in India.

The non-autoclaved block also looks like it's core contained moisture during the heat conductivity test, which could have impacted the temperature reading.

Looks like all the hair my dog sheds might come in handy

It’s likely the added fibers that are allowing the non cured examples to do so well
These blocks were made more differently than merely autoclave vs non-autoclave. That makes these results much less conclusive.
I wish to see comparison of these tests with aac and clay bricks
I think they use aome type of poly fiber mix with cement and sand
In india a fiber by reliance company is used on a ratio of 100 grams per 50 kg of cement

I think the autoclave step is just to reduce curing time/production cost.
How you cure the non-autoclaved blocks? this is very important for the strength sample!
water absorption is normal since autoclave means water is transformed in steam and so one for 16 hours!!! that s mean a stress applied to fast cure for fast production .natural cure maybe add a liitle under certain conditions !but is not economical for factories ! since the blocks are still wet !that s way they embed in plastic de AAC Blocks !plastic capisi ?
The sample has the same batch mix design ? the same has the same cure time ?

hola from Mexico. Can you tell me the water curin
Aac blocks are much better than shown here..they used poor quality aac block.. don't trust it..
interesting video thank you
Is Non autoclaved concrete and CLC blocks the same.?
The difference here is microfibre...has fuck all to do with autoclave
you are kidding yourself to think naac is better than aac
That thermal reader wasn’t exergen.....
This behaves like FRAC rather than NAAC
please tell me Raw materials of non autoclaved aerated concrete with percentage (%) and curing system .now i am working non AAC block

Why the horrible music
вы сравнили газобетон и пенобетон это разные технологии производства.
Hi can anybody help me out to make Non AAC block bcause i am facing problem in getting strength. So plz send me exsact recipe & methode
For all questions, please contact our mail: info@sts54.ru Our official website: www.sts-54.com
Then why do they autoclave the concrete if it's better when not autoclave
Must allow them to charge more.
Speeds up curing process. Faster production.
They are different products doing similar work.
Less moister in the autoclaved aerate means less weight, costs less to ship per payload.
what about the weight coz i know that AAC block are light weight?
Your heat conductivity test appears to be bull shit! Your moving your torch around a large circle on the non-autoclave one, and you are keeping your torch in one spot on the autoclave!

they were both floating in the water test so...
So are companies that sell autoclaves aerated concrete just adding processing in order to justify added cost? Is it because non-autoclaved concrete does not have the inflated profit margin the companies want? That's wrong!!!
I'm guessing it's because autoclaving will cure the product faster, therefore speeding up production.
Nope, they are not the same material fiber in non autoclaved bricks makes the difference.

Why there are fibres in non auto claved block, it is visible in fractured cube
cause they fail in tension. you would see rebar sticking out in a larger block
The fibers add strength. They really add a ton of strength to the product. With and without are two totally different things
Jonathan Trekallover What kind of fibers?
Sac blacks avail for vellore dist sir
I still favour aerated concrete because in earth quake prone areas regular concrete kill people.
No... In Japan , Indonesia, Philippines they use hollow blocks... inserting steel rods... which makes the structure more durable & wall doesnt fall off...

Thank you for that informative data; seems legit. Nas drovia!

Nice
@@edwardfanai5719 correct Sir. ..I think it was wet also

Thanks for information bhai 💖
That was surprising
Non autoclave means CLC?
Not in this case... But CLC is better than AAC in terms of Strength, water absorption & entrepreneurship with low budget
@@olmadepov no sir if you compare with same density AAC have more strength then CLC and CLC clocks are more heavier then AAC
Is CLC better than AAC ?
no
Yes CLC block is stronger than AAC block. Although CLC block takes much time for curing it is more stronger than AAC block. I am an engineer who has worked in both these plants in India.
No.
