Foamed concrete, also called cellular light weight concrete is produced by the mixing of Portland cement, sand including or alone fly ash, water and preformed stable foam. The foam is produced with the help of a foam generator by using foaming agent. The air content is typically between 40 to 80 percent of the total volume. The bubbles vary in size from around 0.1 to 1.5 mm in diameter.
Foamed concrete differentiates from (a) gas or aerated concrete, where the bubbles are chemically formed through the reaction of aluminum powder with calcium hydro oxide and other alkalies released by cement hydration and (b) air entrained concrete, which has a much lower volume of entrained air is used in concrete for durability. Curing of foamed concrete unit may be done as per IS: 456-2000. Curing can be speeded up by steam.
Foamed concrete may be produce by mixing the above mentioned ingredients in ready mix plant or ordinary concrete mixer. Foamed concrete is self compacting concrete requires no compaction, and will flow readily from a pump outlet to fill mould, form, restricted and irregular cavities. It can be pumped successfully over significant height and distances. The 28 days strength and dry density of the material vary according to its composition, largely its air voids content, but usually they range from 1.0 to 25.00 N/mm2 and 400 to 1800 kg/m3. The plastic density of the material is about 150 to 200 kg/m3 higher than its dry density.
Non autoclaved lightweight aerated concrete is a type of lightweight concrete which is used to produce blocks and replace bricks. NAAC is lighter then conventional concrete. It is formed by using portland cement, fly ash, limestone, aluminum powder and water. Aerated concrete has a good strength, durability, good thermal and sound insulation. Dry density of this material ranging between 600 kg/m3 to 1600 kg/m3. Non autoclaved lightweight concrete blocks can be used for housing and commercial purposes.
We have developed a unique non autoclave lightweight aerated concrete recipe and can achieve densities from 250 kg/m2 (even less) with perfect compressive strength, thermal and sound insulation.
PIONER GROUP supply lightweight aerated concrete infill for cold formed steel construction technology infill and we can supply dry mortars (plaster, floor screed, self leveling compound, lightweight aerated concrete dry mix etc.) production line with a good price and speed of delivery.
Wow that volume just rose and rose as you were mixing it
yeah. the only thing you need to do is not stop to mixing it :)

it was a wonderful mass and you notice the lightness
wow, i just found this video and wonder if this recipe is based on your standard recipe with foam added. it just happens i am building a shed and this thing will be very useful in my quest to reduce heat from the roof. thanks in advance, from indonesia 🙏
What kind of mixer are you using? The instrument to mix the aircrete with air compressor? Where can they be purchased?
Make yourself a screed board! - full width scraper
Looks strong, can you share to us you formula? Выглядит хорошо, не могли бы вы поделиться с нами своей формулой? Vyglyadit khorosho, ne mogli by vy podelit'sya s nami svoyey formuloy?
basically you are making aircete correct. at least that is what we call it in English. cement and a stable foaming agent that holds the bubbles until the cement sets up and holds its shape. the foaming agent you use is really good. nice tiny bubbles, it is perfect. I think the R value does not work the same way with this aircrete as with the other types of insulation. it is a different animal. the heat just does not get the chance to make its way outside so quickly so it isn't the same thing as rock wool or fiberglass insulation. it is also very noise insulative as well. the perfect product in a tropical country where your neighbour has a lot of rosters making noise all night long and you can't go out and kill them. this way you don't hear them and you don't get a hot house either. I will be using this method in the Philippines when we get back there. I will be using it for infill between the posts in a poll barn construction. I was wondering about the roof and how far I can go between structural metal roof trusses and not have it fall in. how thick did you pour your roof insulation, was it for a place in Russia for a cold climate? my purpose is to keep the heat out and noise out like I already mentioned. how thick do you think I will have to make it. I was also thinking I can pour it onto thin cement boards and suspend them from the roof trusses on the inside of the home. what do you think of that idea? looking forward to your reply.
also we are doing non autoclaved lightweight aerated concrete but density is higher and R value is not so good.. this is the recipe www.pioner-group.com/concrete
Plz... Provide English subtitle...
IT LOOKS YUMMY:P
:)
hello, is foam concrete more costly or gas concrete or pumice?
Can we achieve density bellow 100kg/m3?
I got a terrace and wants to make it heat proof ....dont wanna add extra roof above it , anyone has any idea?
Wht,is komposision sir??
Muy bueno como hacen la mezcla q proporción??

Almost 90% less from original Concrete density
Lightweight foam concrete can be used for first floor flooring?
Yes. Here the recipe for non autoclaved aerated concrete www.pioner-group.com/concrete
Your foam concrete look like sticky. Do you added additives?
Nope
Is this use just cement and foam?
Yes. Also you can find out how non autoclaved lightweight aerated concrete can be made www.pioner-group.com/concrete
Good day and thank you for posting.
I have a need to produce light weight concrete that weighs about 15lbs/ft3 (240kg/c3) or even less. Was this an accurate number in your description?
Thank You, Bill
Yes Bill the number is correct, this is a low density foam concrete.
@@cellularlightweightconcret1499 This should float nicely in water, have you ever tried?
Good day, I am having difficulties achieving the low density
@@billtabbert8632 use a foam that is stable and also make sure that the air pressure is correct to create the foam at the correct weight per litre. you can look at some of the aircrete videos to find out what that is. most of the time I see people providing airpressure at 90psi in order to create the foam at the appropriate volume so you can make a stable aircrete which the guy is making in this video. this 200kg/m3 is perfect for infill between centers in a poll barn construction which I will be doing once I can get back home and start building. after watching this video, I think I will use the foam cement to insulate my roof as well. in a tropical climate this prevents the walls from becoming a thermal mass that only keeps heating your house during the night. just have to find the best foaming agent you can I think there is one called drexil or something like that name. some guys use a dish soap and put something else in there to stabilize the bubbles. that is the thing that you need to do the most stabilize the bubbles so the cement can set up and then you are off to the races.
@@kusnezoff8705 Do you know what I can use to stabilize the bubbles? thanks!
I am interested in your technology

What is the R value per inch for insulation.
Thermal conductivity is 0.06 W/m*K
@@cellularlightweightconcret1499
To get r value per inch you take the length of an inch in meters and divide by U value. So R= 0.0254/.06=0.42 which is a terrible R value. To meet building code in northern USA you would need a wall 45 inches thick
@@danjimielson We are not working in the USA. We are working in the country where people don't like rock wool or glass wool and prefer solid buildings. To achieve U-Value 0.34 W/m2*K we use: fiber cement board 9 mm thickness + Light gauge steel profile 200 mm (with insulation 75mm lightweight concrete with 400 kg/m3 density + 50 mm polystyrene with 22 kg/m3 density +75mm lightweight concrete with 400 kg/m3 density) + fiber cement board 9 mm thickness.
@@danjimielson Cellular lightweight concrete of 300 kg m3 has an R value of around 2.5 so I would assume this lower density concrete would have an R value of 3 +
What are the additives to cement?
Some king of superfoaming soap, or anything that foam good like proteins...
What ingredients did u mix ?

How to Increase strength??? More than 800 1000 psi?
For which density you need such compressive strength?
A one
What cement and water rasio did you use?
I mean when you mixed cement and water
For 1 m3 of lightweight concrete you need 160 kg of cement and 50 - 60 liters of water
what is the foam agent you use to get this density of foam please
Did you meant 160 kg of cement and 60 l water for density 200kg/m3?
Thank You.
160kg cement and 40kg sand?

It seems this is the only channel that is disclosing a little bit of an industry wide silence on this science of lightweight concrete.
No! it doesnt use foam, rather it is an additive called aluminium sulphate of which the ratii is about 4% of the cement and lime mix. That is the big question?
How much or how little of alum does one use.
I dont know if they add sand, but its the formula which is a well kept secret.
I'm disclosing this info cause I would like to see more you tubers experimenting and disclosing your results.
But nonetheless, lets give credit where credit is due. Great videos, however I and many others would love to see a somewhat more detailed video with formulas.
But then, its all about marketing and the oroducts you guys are trying to promote.
