Useful information, thanks. Also make vdo for its advantages.
Too Good Sir,
Pls make a video on Lime Plaster , it's advantage and disadvantage
Yes I think next level safety for acc block video
Thnx sir valuable knoledge
Thx sir, keep continue
Awesome sir......
Nice video sir, thnk u
Very much useful
Thanks
Very useful information.
Can we use this in outer boundary's wall?Does it effected by rain,or in delhi summer?
Great knowledge, sir aap ye video live main aa k banaye
Thanx sir supv video
Very informative, I appreciate. Can you give me the advantages video link. thanks

Advantage of AAC Blocks - ruclips.net/video/B9E2pUUu5ak/видео.html
Thank you sir... please make advantage of AAC block
Advantages are that work is real quick.
You don't need curing for even single day. Cost of sand and cement + shifting cost is zeroo . Shifting cost to heights minimised because they are real light.
Plastering not required if Massonary is done neatly. Direct wall putty and then paint.
Well explained... superb👍🏻
I am using these blocks for elevation purpose. Constructed a 4" block Wall leaving 2" between red brick wall and aac block. Later, we have poured concrete between these 2 walls. Does it develops crack ?
Very nice video sir.
Please make a video on use of fly ash bricks as they are good alternative of red clay bricks. They are also green building material.
Please tell us about their pros and cons.
Bhut aache bhai
🙏🙏
It’s very useful video, please post AAC blocks advantages also

Bro our shop is approx 2000sq feet rectangular and two sides open to road
Please tell me what cares should be taken while builting.
Thank goodness
Wanted to make sculpture of AAC blocks height 20' is it possible ? What precautions I need to take? I was planning to make steel structure to make it hollow , please let me know, thanks
Good explanation
Thank you. Please make a session on "Manufacturing process of AAC blocks and basic tests".
Thank you so much,
Otherwise it has more positive advantage
Best explanation thank you keep it up with the valuable information thanks a lot ABT the aac block.
Please upload more video regarding normal bricks Vs aac block as per ur research and please educate us with cost effective and which is better ..
Ultimately AAC Blocks to be used in construction activities with several benefits , already known and accepted by builders have already penetrated 70% market in metro cities ,Moreover, States and Central govt has already banned several brick kilns and few state govt mandate consumption of fly ash bricks and blocks in 300 kms radius of TPS.
Being an Civil engineer and involve in close supervision of the construction sites states here the major causes of cracks:-
1) Poor workmanship:-Mishandling and additional curing practise.(Not required any curing during and post masonry works.)
2) Dry shrinkage:-These blocks should be allow to dry for 72 hours as contains 20% moisture post Autoclave curing and advice to dry completely to settle volumetric changes prior to masonry works,also not required any curing during and post masonry works as already cured during auto claving.
3) Compressive strength:- The AAC blocks having compressive strength more than 4N/mm2 already mentioned in IS code are safe and can be use masonry works.
4) Cope beams:- Above 1.2m of wall height at a time only cope beam is required rather than column or other member to compensate load.
5) High Ratio cement Mortar;- Avoid cement sand mortar.............Special ready mix mortar is available in market which should be used during masonry work,it also absorbs minor volumetric changes if comes due to thermal expansion and contraction and prevents any cracks.
Conclusion:- Its and excellent engineered material replacing the traditional clay bricks with below given benefits:-
Benefits:-
1)Light in weight:- Reduced dead weight of building and ultimately reduces cross sectional area of column beam and save concrete and steel.
2) Speedy work:- Larger size blocks leads to faster construction.
3) Fire resistant:- can resist upto 6 Hrs as already made up of flyash.
4) Workability:- Allow proper cutting of block and minimizes wastage.
5) Enviornment friendly:-Resource efficiency gives it lower enviornmental impact in all phases of its life cycle.
6) Sound insulation:- Acoustic proof.
7) Thermal insulation:- Cool in summer and warm in winter season,also save air conditioning charges.
8) No water seepage:- As pores are interlocked avoid capillary action.
9) Cost saving:- No need of plaster in Internal face and one coat of plaster 10-12mm is sufficient on external face.
10) Usabililty:- Available in different shape and size in market.
Above points written after observing block works in 7 massive construction sites in NCR.
BITTER TRUTH:- Site contractors never advice their clients to use this as it reduces labour work and ultimately their income.
@@zeeshanaliquazi8563 bhai bohot hi zabardast analysis maza aa gaya please give me your mail id i have something to ask you regarding aac blocks usability in house construction.
Make a video on disadvantages of Clc brick's
Sir Eyes Bunglow banane ke liye kya isa use kar sakte hai
Hi cracks aaye hy uska solution btaye or ek season (full garmi) k baad cracks or bade ka khatra bhi hy kya
Good one
Sir Foam concrete is not AAC. AAC is produced with cement flyash aluminium powder and gypsum. Where as foam concrete is produced with mixture of cement sand /flyash and foaming agent . Please correct in the beginning of the video. Also foam concrete blocks strength increases day by day through its life . Where as AAC block strength is achieved within 3 hours. Foam concrete blocks are more durable than clay bricks due to its slow strength gaining properties, also foam concrete blocks are heavier than AAC blocks . Cracks due to stress concentration never appear in foam concrete blocks . But crack due to stress concentration are very common in AAC blocks
Other information your provided is in the video is correct 👍
100 % percent agreed with what you said because it happened in my house wall. Now please tell how to repair thecracks because nothing which I tried is working.
The wall is 10 cm width. I had used runners at 1.2 mt height and even column at 3-4 mt distance apart.
I used adhesive chemical.
Material was bought from neolite company.
Abi kya crack aa rahe h aapki wall me hum bhi ye block use krna chahte h
Do CLC block has the same problem?
Nice sir
Tanku you sri muer iadeas
Excellent video
Thank u sir
Sir CLC block block ka disadvantage bataea.
very useful. please upload more
bhai very informative video. CLC ka bhi ek informative video jaaroor banana
Sir adhesive konsa accha hoga?
Superb, & excellent information as for as as new owners are concerned, as they're less aquinted with these civil engineering aspects , & it's products.
Coool bro.... But how can I believ wtevr u said is right, like the rations which u r taking,
Please make a video on disadvantages of CLC block.
Hi Friend , good explanation, can you advice , how n where put adhesive?
ruclips.net/video/ZXuKMdZM9Rg/видео.html - Watch this link for use of AAC Blocks
Is it same with sand based CLC block?
Sirji please make a new video why we need to use AAC why not other traditional material...
Red brick , Maharashtra light weight brick.concerete , CLC...
Help the ppl which one would be good ...
Nice video Sir
AAC block mai loft ki report kaise hai? Hum loft kar sakte hai na?
Good info
Runner cement se banaye ya adecive se
Try Izoblok, lightweight building block with many benefits. Not prone to cracking
Thanx frnd remember this thing in mind
I would also like to know about use of masonary material... wheather to go for Cement Mortar or Block fix Chemical?
Hi Niraj, if you r asking my recommendation - Don't use AAC block in your own house, there are lot of factors to develop the cracks in Future. As handling, stacking method, way of installation, location of lintals, etc.
If you want than go ahead with aac use adhesive and thickness of layer bond appx 2-3mm
Plz make another video of AAC block
Nxt time keeping high sound.
Good correct
Can we use it for 8 ft height boundary wall and will it be cheaper than usual red brick wall??
There will be 100 % settlement cracks later as it has to be done on slab or beam to reduce settlement movement.
Acc block ya diwal par nimmu atha kya
Very nice vifeo
Can we do cement plaster on aac wall, same as we do in red bricks case?
Yes, you can
Ok.which is best.?
It seems like the problems here are foundation related, rebars should also be used through out to secure walls to foundation, including a "bond beam" at the top. Control joints should be used where required. Use more lime in you stucco mixture as just cement and sand stucco will increase risk of cracking, it is ideal to use fibre mesh between block and plaster. I have build many homes with AAC and have never encountered your problems.
Can you please share the complete steps with pics / video for AAC block construction (best practice).?
First class brick c.stength is 10N/mm2
Correct me if im wrong...
We can say yes, but for your information and clarity according to IS 1077 : 1992 bricks has strength has classified from M35 to M3.5 N/mmsq strengths, but in use of sewer works bricks strength should not be less than 12.5 N/mmsq as per CPWD.
Hello sir my work is 600 sq ft frame structure hard strata is below the foundation just tell me which i prefer brick or aac block
Its my house please tell me..?
Yes, you can
Generally for one and two storey house.. Red bricks are best... Don't go for aac block
@@mujiburrahmankhan1577 red bricks arent eco friendly.
Brick masonry preferable below foundation as have better CS and can withstand with lateral forces.

Sure
Jab hum Ghr banane k starting point pe the to ambhuja company ki taraf se representative aaye the unho ne hi humko Block use krne k liye bola
I was about to buy foam concrete blocks... But thankyou.. I am stick to red bricks.
No go to CLC lightweight blocks .. it's so good product.. water cured and low water absorption.
CLC is always best then red brick
@@kirujc731 AAC or CLC bricks m different kya h.... Or dono me best kon sa h.... ????
@@mukeshkumarjain4891 bro sorry i don't know hindi can you tell in English
@@kirujc731 Best bricks in AAC and CLC bricks Which one? Especially when a two-storey building is to be built.
Best hai
Good video. But has been recorded at a very low volume.
Sir how to fill the gaps when the wall reaches ceiling
Sir,curing is necessary in AAC block...??
No, AAC block don't need curing,
Then what is dry shrinkage???
any "new" product being mass marketed in the developing world is highly suspect. show more seismic and impact tests of these blocks glued together without internal interlocks.
Narayan Bless 🙏 You
Tell me the benefit of using AAC blocks?
Places of manufacturing?
Iska plaster k liye kya use kare
Cement mortar. Or adhesive
For domestic use.....??
One wall I did with direct asian wall putty cement base and outside I did sand cement mortar, but sides perfect.
But need to moisten the wall before plaster and curing the plaster regularly, nahi to crack hi crack aayega bhai. Because acc block sucks water from mortar very fast. Hope this helps.
For plastering I would suggest wait for a couple of months to see if there are any settle ment cracks
Why are there cracks in fly ash bricks masonry wall? Specially in summers
👍👍👍
informative but we can take care, cannot leave.
Fly ash brick ke bare me bataye
please provide the repair solution after cracks formed in the AAC wall. Please note:: Cement plaster and POP punning have also been done. So please give us the best solution of cracks repair
Same happened with me sir please help
First use either Roadware 10 minutes crack sealer or dow silicone in liquid form to fill and repair the cracks permanently...
Then use stiff buckram on crackes with anabond...it would resolve the problem hopefully...

Always use AAC block having Compressive strength more than 4 N/mm2 and ensure the first layer should be exact horizontal with spirit level and vertical with plumb bob before laying successive layer....
Very awesome..
Bhai mai sirf wall chadi karna chahta hu bina load ke kya mujhe runner dalna padega
Yes at height of 2400mm
👍
Make video of CLC blocks
Aac block mein ghar banana sahi hoga ya red clay bricks accha rahega.please suggest.
Clay / flyash bricks, both are good option, dont use AAC block
But sabi to iska advantage jada bol raha hein.
Bro its your house, dont take risk for use of AAC blocks that can make problams, cracks in future
Factual Civil Engineering Then why did u share video of AAC block benefits and encouraging others to use it in construction???
What is the Advantages of AAC Block?
Please explain my
l have very bad experienced with acc block,several cracks are arise after wall putty and also the wall tally have been crack
Cracks are possible in regular bricks also cement curing, watering is more important
Sir band k bad bhi crack aate h, kyu
Ye nails ya PVC grip or screw hold karta hai ya nahi
Use either drill bit or rawal plug
Your video is informative but the heading on the theme page is misleading.
True, I watched it because was looking for some best solution for fixing cracks. 🤣🤣🤣🤣
Nice video please make one for the advantage also
