What is Aircrete and how do I make it?

This is the Little Dragon System and a great video on  producing Aircrete. The process is so simple and safe and low cost.

Aircrete block casting

This is similar to a system I would like to use in California  to cast Aircrete blocks to recover from wild fires. My plan would be to get 1000 block molds to cast 6000 blocks a day. The goal would be to reach 1 million blocks  in about 180 days enough to build about a 1000 or more new homes for those hardest hit. 

This is a longer video of the same kind of building system in the first video. 

Metal Stud /Aircrete System

This is the other building system I will be offering to rebuild the state of California. This is a good option for more conservative building depts. As all structural support is provided by the steel studs.

Dome Systems

I attended the Dome building workshop and can also build a dome for you.

Aircrete FAQ's

What is Aircrete?

AirCrete is a lightweight cementitious material that contains stable air cells uniformly distributed throughout the mixture. It is a concrete which utilizes a stable air cell rather than traditional aggregate. It is also called cellular concrete, foam concrete, light weight concrete, aerated concrete etc. 


What is the correct water to cement ratio for the cement water slurry?

Typically, a (1 to 2) water to cement ratio slurry is used as a base mixture for AirCrete. The water cement ratio may be varied according to specific project requirements. We use 6.5 gallons to 94 lbs of cement.

Does AirCrete contain either fine or course aggregate? 

AirCrete may contain sand but not coarse aggregates. Air-crete is designed to create a product with a low density and a relatively lower compressive strength when compared to plain concrete. The typical density range of Air-crete is 20 – 60 lbs/cu.ft. which develops a corresponding compressive strength range of 50 psi – 930 psi. When higher compressive strengths are required, the addition of fine and less foam will result in a stronger concrete with resultant higher densities. 

What type of cement is appropriate for AirCrete?

 AirCrete may be produce with any type of portland cement or portland cement & fly ash mixture. The performance characteristics of type II, type III and specialty cements carry forward into the performance of the AirCrete. 

How much AirCrete does a bag of cement produce?

 A 90lb bag of cement produces 40 - 50 gals of AirCrete.

What are the advantages of AirCrete?

 There are many benefits to AirCrete in the appropriate application. It is inexpensive to produce, it has good compressive strength, it bonds well,  easy to work with, self compacting, self leveling,  uses less material,  and offers  enhanced sound and heat insulating properties.  AirCrete is very easy to clean up and can be remove with only hand tools. 

Are there different methods for manufacturing AirCrete? 

AirCrete is commonly manufactured by two different methods. Method 1 consists of mixing a pre-formed foam into the cement and water slurry. Method 2 consists of the addition of reactive substances, which produce gas bubbles when in contact with the cement and water slurry. 

What are the advantages of pre-formed foam?

The pre-formed foam process assures a consistent distribution of air cells. 

What are the disadvantages of AirCrete compared to typical concrete?

In the lower density ranges AirCrete becomes more brittle and has less compressive strength than plain concrete. While this may be a disadvantage in plain concrete applications, it is an advantage in an AirCrete application. It should be considered that AirCrete and plain concrete are used for different types of applications. Each form of concrete exhibits a unique family of performance characteristics. Each should be utilized in the appropriate type of project. 

What construction projects are appropriate for AirCrete?

• Housing Systems 

• Precast Blocks and Panels 

• Floor Slabs 

• Poured Insulated Roof and Floor Decks 

• Underground Pipe Insulation 

• Acoustic Floor Underlayments and Shock Absorption

• Load Reducing Fill over Underground Structures 

• Fill for Abandoned tanks, mines and pipelines 

• Replacement for Unstable Soils

• Bridge Approach Fills 

• Land Fills


Do the bubbles in AirCrete collapse, reducing its volume? 

Yes it does collapse in the case of vertical pours where the force of gravity exceeds the air cell strength.  Air cell stability is the mark of a good foam concentrate and foam generator combination. Which is not to say that all AirCrete products are stable. If you unfamiliar with the foaming agent you should test the foam for stability prior to use. With dish detergent as foaming agent expect some collapse if the depth of pour exceeds 3'.

What Ad Agents are common to AirCrete? 

Fiber reinforcement - Heat-of-hydration reducers (iced water or chemicals) - Compressive strength enhancers - Coloring pigments or color enhancing agents 

How far can AirCrete be pumped? 

Documentation of AirCrete being pumped 500 ft. vertically and 10,000 horizontally is common. 

How do you finish AirCrete? 

In most cases AirCrete is covered by another material. It make a good sub floor but can't be polished like regular concrete. The exterior walls are best covered with a thin layer of water proof crack resistant stucco. Interior walls can be finished with a thin layer of plaster and paint. It is a excellent base for natural plaster.

How much does AirCrete cost? 

This depends of several factors. The density, the cost of cement, the additives etc. To calculate the approximate cost of AirCrete for a dome structure, including subfloor slab - multiply the square feet X the inches of thickness. For example a 1000 square foot dome 4 inches thick will cost about $4000.

Is AirCrete suitable for long-term use as a marine float device? 

AirCrete  will float, and in many cases float indefinitely. For best results AirCrete used for marine flotation should be encased in a protective membrane or shell. 

Is it appropriate to reinforce AirCrete with fibers? 

Yes, fiber will increase the tensile strength. Fiber reinforcement is a mechanical process and does not have any effect on the chemistry of concrete. It is therefore perfectly acceptable to design fiber reinforced AirCrete  just as it is done with other forms of concrete. 

Is it appropriate to reinforce AirCrete with steel? 

Yes, steel reinforcement is appropriate in situations where more tensile strength is required. There is no chemical or mechanical reason not to reinforce AirCrete with steel. 

What is AirCrete's R-Value?

While researching the question about R value I found this article by David South. It confirms my belief that there is a lot more to creating a insulated wall then R value. AirCrete can make a comfortable home that is easy to heat and cool. 

One of the fairy tales of our time is the "R-value."  "R-value" is touted to the consumer to the point where it has taken a "chiseled in stone" status. The saddest part of the fairy tale is the R-value by itself is almost a worthless number.

It is impossible to define an insulation with a single number. It is imperative we know more than a single "R" number. So why do we allow the R-value fairy tale to be perpetuated? I don't know. I don't know if anybody knows. It obviously favors fiber insulation. Consider the R-value of an insulation after it has been submersed in water or with a 20 mile per hour wind blowing through it. Obviously the R-value of fiber insulations would go to zero. Under the same conditions, the solid insulations would be largely unaffected. Again R-value numbers are "funny" numbers. They are meaningless unless we know other characteristics.

None of us would ever buy a piece of property if we knew only one dimension. Suppose someone offered a property for $10,000 and told you it was a seven. You would instantly wonder if that meant seven acres, seven square feet, seven miles square, or what. You would want to know where it was -- in a swamp, on a mountain, in downtown Dallas. In other words, one number cannot accurately describe anything. The use of an R-value alone is absolutely ridiculous. Yet we have Code bodies mandating R-values of 20's or 30's or 40's. A fiber insulation having an R-value of 25 placed in a house not properly sealed will allow the wind to blow through it as if there were no insulation. Maybe the R-value is accurate in the tested material in the lab, but it is not even remotely part of the real world. We must start asking for some additional dimensions to our insulation. We need to know its resistance to air penetration, to free water, and to vapor drive. What is the R-value after it is subjected to real world conditions?

The R-value is a fictitious number supposed to indicate a material's ability to resist heat loss. It is derived by taking the "k" value of a product and dividing it into the number one. The "k" value is the actual measurement of heat transferred through a specific material. 

Test to Determine the R-Value

The test used to produce the "k" value is an ASTM test. This ASTM test was designed by a committee to give us measurement values that hopefully would be meaningful. A major part of the problem lies in the design of the test. The test favors the fiber insulations -- fiberglass, rock wool, and cellulose fiber. Very little input went into the test for the solid insulations, such as foam glass, cork, expanded polystyrene or urethane foam.

The test does not account for air movement (wind) or any amount of moisture (water vapor). In other words, the test used to create the R-value is a test in non-real-world conditions. For instance, fiberglass is generally assigned an R-value of approximately 3.5. It will only achieve that R-value if tested in an absolute zero wind and zero moisture environment. Zero wind and zero moisture are not real-world. Our houses leak air, all our buildings leak air, and they often leak water. Water vapor from the atmosphere, showers, cooking, breathing, etc. constantly moves back and forth through the walls and ceilings. If an attic is not properly ventilated, the water vapor from inside a house will very quickly semi-saturate the insulation above the ceiling. Even small amounts of moisture will cause a dramatic drop in fiber insulation's R-value -- as much as 50 percent or more.

Vapor Barriers

We are told, with very good reason, that insulation should have a vapor barrier on the warm side. Which is the warm side of the wall of a house? Obviously, it changes from summer to winter -- even from day to night. If it is 20 F below zero outside, the inside of an occupied house is certainly the warm side. During the summer months, when the sun is shining, very obviously the warm side is the outside. Sometimes the novice will try to put vapor barriers on both sides of the insulation. Vapor barriers on both sides of fiber insulation generally prove to be disastrous. It seems the vapor barriers will stop most of the moisture but not all. Small amounts of moisture will move into the fiber insulation between the two vapor barriers and be trapped. It will accumulate as the temperature swings back and forth. This accumulation can become a huge problem. We have re-insulated a number of potato storage's which originally were insulated with fiberglass having a vapor barrier on both sides. Within a year or two the insulation would completely fail to insulate. The moisture would get trapped between the vapor barriers and saturate the fiberglass insulation to the point of holding buckets of water. Fiber insulation needs ventilation on one side; therefore, the vapor barrier should go on the side where it will do the most good.

     We understand air penetration through the wall of the house. In some homes when the wind blows, we often can feel it. But what most people, including many engineers, do not realize is that there are very serious convection currents that occur within the fiber insulations. These convection currents rotate vast amounts of air. The air currents are not fast enough to feel or even measure with any but the most sensitive instruments. Nevertheless, the air is constantly carrying heat from the underside of the pile of fibers to the top side, letting it escape. If we seal off the air movement, we generally seal in water vapor.

The additional water often will condense (this now becomes a source of water for rotting of the structure). The water, as a vapor or condensation, will seriously decrease the insulation value -- the R-value. The only way to deal with a fiber insulation is to ventilate. But to ventilate means moving air which also decreases the R-value.

Air Penetration

The filter medium for most furnace filters is fiberglass -- the same spun fiberglass used as insulation. Fiberglass is used for an air filter because it has less impedance to the air flow, and it is cheap. In other words, the air flows through it very readily. It is ironic how we wrap our house in a furnace filter that will strain the bugs out of the wind as it blows through the house. There are tremendous air currents that blow through the walls of a typical home. As a demonstration, hold a lit candle near an electrical outlet on an outside wall when the wind is blowing. The average home with all its doors and windows closed has a combination of air leaks equal to the size of an open door. Even if we do a perfect job of installing the fiber insulation in our house and bring the air infiltration very close to zero from one side of the wall to the other, we still do not stop the air from moving through the insulation itself vertically both in the ceiling and the walls.
