How to Build a Aircrete Foam Gun! *LOW PRICE*

AirKrete is a thermally efficient and environmentally responsible, non-toxic insulation, which is easily foamed into open or closed cavities in walls, roofs and ceilings. Its basic raw materials components are air, water, and MGO cement, which when combined, create a cost-effective, safe and high performance product. Developed over 25 years ago, AirKrete's efficiency is both time and test proven. At the time of application, its consistency is like shaving cream and after it cures, AirKrete is an ultralight weight cement to maintain long-lasting, high insulation value.

Many clients, including the Audubon Society realize the outstanding technical and environmental qualities of airkrete. The Audubon Society installed airkrete in their Headquarters in New York City, a building, according to its architect, Randolph Croxton, that was designed to "create a model headquarters Just a couple of weeks after Airkrete was installed at the Betance Apartment Building in NYC, an electrical fire broke out in the top left apartment.

As the alarm went off, the firefighters feared the worst - they had witnessed the devastation when a fire swept through a dated building in the Bronx. In this case, the outcome was different. Fireproof Airkrete stopped the fire in its tracks - lives were saved, and the firemen thanked the owner for a smart decision! What property of yours deserves Airkrete? Create a cocoon of safety for your family by enclosing your home's bedrooms with Airkrete!

The fireproof insulating qualities of Airkrete creates a barrier of protection against heat and flames. The protected walls, ceiling and floors can't burn, and you get the extra time needed to save precious lives! Many chemically sensitive people just can't tolerate spray polyurethane foam SPFphenol-formaldehyde foam or urea-formaldehyde foam insulation!

Now that's a breath of fresh air! When the most enviornmentally safe insulation on the planet is installed in your home, there's no need to move your pet, cover your aquarium or get out of the house!

Airkrete is not a spray polyurethane foam SPFbut an ultra light magnesium oxide cement insulating foam - which means no toxic fumes and no danger to animals or people. It's the answer to cozy, healthy living with no toxins ever in your home environment Now that's something to bark about! The basic components of Airkrete insulation are air, water and magnesium oxide, which when combined in Airkrete's proprietary formula, creates a shaving cream consistency.

After it cures, Airkrete hardens into a lightweight, stable substance with a great R-value and atmospheric cleaning powers that make the air around it fresh and oxygen rich! This is in addition to the fact that Airkrete is also fireproof, serves as a pest and mold repellent and gives off no toxic fumes. There is simply no safer insulation for your home or work environment on the planet!

Here's a word you should know as a homeowner: "desiccant". It means a substance that induces or maintains a state of dryness. This process of "absorption" is the attribute of Airkrete that keeps away vermin. They can't nest or live in Airkrete or they mummify!

Goodbye nesters! Termites, wood bees, carpenter ants, spiders and other nasties cannot survive burrowing through Airkrete due to its abrasiveness it wears away their exoskeleton and de-oiling effect, which dries them up! The bugs can't live where we foam, literally crawling out of the walls bringing their larva with them!

The magnesium oxide Airkrete foam is beneficial to us - Airkrete is fireproof, non-toxic and scrubs CO2 right out of the air - but deadly to insects. How cool is that? With Airkrete's sound reduction qualities, you'll have no more sleepless nights. Another noise to wake you up when you can sleep in? Fix it with Airkrete! Walls with a new installation of airkrete! With Airkrete insulation, you'll have a sound barrier rivaling the quiet of recording studio acoustics. The sound of silence! The rebirth of the George B.As a result of the guidance provided by the Government and Public Health England, all APA members will cease Aircrete product production as soon and as safely as possible while continuing to review the situation to act accordingly.

We've recently undergone a rebrand, with a new logo and colour ways, reflecting the innovative nature of our product group. As a sector producing UK manufactured bricks, blocks and mortar the MMA are encouraged that the Government has responded by focussing on increasing the supply of homes, and the ambition of delivering a million new homes in England by Broadly, the industry is responding to this need.

Throughout the UK there was significant investment inand there is further investment forfor example old plants are being replaced to increase production rates or new additional production lines. Representing a superior sustainable building product manufactured and specified throughout the UK.

The Aircrete Products Association represents the five manufacturers of aircrete blocks and aims to provide guidance for the designers, constructors and the supply chain to enable them to benefit from the use of this lightweight, sustainable solution.Though history records the use of concrete blocks by the Romans, Greeks and even Egyptians some of the two-tonne blocks that make up the Pyramids are believed to be a primitive form of concretemodern-type blocks were first cast, albeit in modest quantities, in around the middle of the nineteenth century.

InJoseph Aspidin devised the basic mix that we would still recognise today. The mix, cast in wooden moulds, consisted of powdered limestone and clay mixed with water.

In the early twentieth century block manufacturing became an established industry.

Air-crete Building

These early lightweight blocks were popular as internal partition walls because of their ease-of-use and cheapness, but it was only as a result of the development of cavity walls and the advent of mass housing programmes of the post-war years that the industry dramatically expanded.

Cavity walling became adopted in the s led by house-builders Costains because, although slightly more expensive to build, the perceived advantage was that the technique successfully overcame the problem of water penetration that traditionally plagued solid masonry wall construction. Early cavity walls used brick in both leaves, but as the economics of using a cheaper substitute became apparent, concrete block largely replaced brick as the inner leaf from the s onwards.

In use from the s onwards, dense aggregate blocks are very much the work-horse of the construction industry. Their distinctive properties of durability and strength make them an ideal and cost-effect solution for all types of load-bearing walls.

Dense aggregate concrete blocks are manufactured from cement, sand and aggregates. Produced in greater volume, but less strong than dense blocks, lightweight blocks are used in both internal and external walls where loading is slightly more restricted or as infill blocks in beam and block flooring. Their main advantage over dense aggregate blocks comes from a combination of higher insulating properties and a lighter unit weight.

The lighter block enables time and material cost savings through easier handling and larger units. Units the same size as other block types. Though limited to structural applications in low-rise construction and partitions as well as a component of curtain walling in higher buildings, aerated blocks can perform a similar range of functions as dense and lightweight blocks.

The blocks are made from cement, lime, sand, pulverised fuel ash PFA and water. PFA is mixed with sand and water to form a slurry. This is then heated before being mixed with cement, lime and a small amount of aluminium sulphate powder. The aluminium reacts with the lime to form bubbles of hydrogen. When the mixture is partially set, it is cut to block size and transferred to an autoclave where it is high pressure steam-cured to develop strength.

The environmental impact of concrete blocks. The major environmental impact caused in the manufacturing of concrete blocks derives from the use of cement. The quarrying, processing and transportation of land aggregates contributes to the depletion of resources, degradation of the landscape and the consumption of water and energy.

Marine extraction continues to provoke debate over the long-term effect of offshore dredging, particularly on coastal erosion, fisheries and other marine life. Products are available on the market that incorporate recycled aggregate to replace virgin quarried aggregate.

Secondary aggregates are the by-products of other extraction or industrial operations. Secondary aggregates, including such like as colliery spoil, china clay waste, foundry sands and blast furnace slags, when used in concrete, reduce the demand on natural aggregates whilst simultaneously diverting significant quantities of waste from landfill.

Blocks: Concrete masonry and its alternatives

The blocks can be used both as the inner leaf in cavity walls or as a single skin for external load-bearing construction. As well as their use in walls, clay honeycomb blocks can be used in many of the same applications as concrete blocks. The blocks are formed with a cellular structure of vertical perforations that reduces the material quantity as well as weight whilst providing an increased thermal performance.

Blocks are assembled through dry vertical interlocking and thin-mortar horizontal jointing. Hemp blocks, although new to the market, are based upon a cast or spray-on technology that has been available for several years. The blocks are supplied in either load-bearing or non-load-bearing formats. Hemp blocks are manufactured using hemp blended with a lime and cement binder. Blocks manufactured from unfired clay are still uncommon in modern construction — this is despite their excellent environmental credentials.These easy-to-follow steps show how to make your own concrete blocks.

A helpful diagram is provided. I've had to do the same thing. There is another alternative, though. Some forms I've designed for that purpose might, I think, be helpful to do-it-yourself builders. The accompanying diagrams show how they work. As you can see from Fig. The holes are created around pieces of plastic drainpipe as each course goes up Fig.

Most block construction calls for an 8" X 16" footer. I'd suggest building forms for the wall's base from 2" X 8" boards, and then using the same lumber for the block forms after the footer is done. Several molds will make the concrete work go a lot faster.

The height of the block can be controlled by the form's end plates see Fig. If you goof on your measurements, just make the necessary correction by raising or lowering those pieces. Also, leveling can be adjusted by means of small wedges under the same panels.

A note on making the holes: Set the pipes in place, pour the concrete, wait about an hour and rotate the lengths of plastic a few times so they won't freeze in position. My method can, of course, be used to cast block of different sizes.

For instance, if you want to build a hotbed or compost bin with four-inch-thick walls, pour a 4" X 10" footer and use one-inch plastic pipe to form the holes. Casting your own concrete units in position has several advantages. For one thing, if you're a weekend builder of a place in the country, you won't have to worry about someone ripping off your blocks in your absence.

Or, if you're building and gardening too, you can just fill as many forms as you have time for and then go back to the bean patch.

The Woodland Homestead.We researched many construction methods. And we examined the green potential of each along with the the expense and efficiency of construction. In the end, we settled on using AirCrete.

AirCrete is a lightweight material that contains stable air cells uniformly distributed throughout a concrete mixture. It is, essentially, a concrete which utilizes a stable air cell rather than traditional aggregate. AirCrete has many names including cellular concrete, foam concrete, light weight concrete, aerated concrete etc.

The Philippines can get hot. Keeping a home cool with minimal air-conditioning is an important component. Construction is always an issue in the Philippines as the population is generally young. This results in inexperienced labour. Additionally, the economic boom means a lot of construction is already underway resulting in a lack of experienced labor.

AirCrete resists heat and fires far better than most other building methods. AirCrete construction is fast, efficient, almost fool-proof despite lack of training and experience with laborers. It requires a minimum of labour. The formwork is erected, After all pipes for water, electricity, etc are put in place and the airCrete is poured. The result is a strong, bugproof, fireproof, earthquake resistant, wind and water resistant structure that is low cost and durable.

Skip to content. We wanted to preserve the environment, reduce pollution and reduce costs at the same time. What is AirCrete? AirCrete should not be confused with a similar but different product named AirKrete.

AirCrete densities range down to 20 lb. AirCrete is produced by infusing a concrete mixture with soap foam. Why build AirCrete homes?Please enable JavaScript on your browser to best view this site.

Air-crete 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. Air-crete densities range down to 20 lb. 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 Air-crete. The water cement ratio may be varied according to specific project requirements.

Does Air-crete contain either fine or course aggregate? Air-crete 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. 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 Air-crete? The performance characteristics of type II, type III and specialty cements carry forward into the performance of the Air-crete.

What are the advantages of Air-crete? There are many benefits to Air-crete 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. Air-crete is very easy to clean up and can be removed with only hand tools. First, I want to compliment them on their excellent video, photography and stunning design aesthetic.

The fact that this home has been reposted on countless websites shows how popular it is. However, I do have some comments and questions: — how thick are the dome walls? Do you add something special to repel water?

Hi, do you know if using the portland in air-crete will cause problems with surface mold over time? I have a mold allergy and I know that regular cinderblocks can mold up. Any material can support mold growth. It is moisture that allows mold to form. Best to use materials appropriately in an building envelope assembly by following the principals of building science.

Depends on what is needed: -New wall construction? Infill, structural needs? If she currently has insulated cinder block walls right now and has a moisture issue causing moldy indoor air quality, then probably look at the basics: gutter cleaning or install, downspouts piped away from house, proper grading of foundation, vapor barrier in crawl space, proper air sealing at penetrations, mechanical dehumidification, etc.

If the CMU walls are not insulated or sided sufficiently, then they will be moist. Take the moisture and food away from the assembly then the conditions that support mold growth will not exist.Elongated racetrack shape provides optimum headroom and versatility. It is specifically designed to be assembled in a matter of weeks by unskilled labor. Constructing it is as simple as putting together Legos. Air-Crete is the most practical, high-quality, low cost material there is.

It is easy to make, easy to work with and requires only basic skills. With its 18" thick building blocks, the dome not only meets but exceeds building code. Air-Crete has an insulation value ranging from R3 to R6 per inch.

AirCrete Construction – Building AirCrete homes.

There are no thermal bridges in an Air-Crete dome; it is a sealed envelope with no air leakage. On top of that, the seamless integration of floor, walls and roof allows the natural flow of interior convection currents that make it easier to heat and cool. The dome will incorporate the Bernouille chilling effect for passive cooling. In short, conventional homes take too long to build and cost too much.

There is no need to create the dome curve because the curve is inherent. Self-insulating building blocks do away with the labor and expense of adding insulation. Large, light-weight building blocks make the dome less labor-intensive than other dome designs. The largest block at 55 lbs. However, when blocks are poured in place, weight is not a concern. The DIY dome is a low-profile sphere with natural air flow.

To keep it simple, and so as not to interrupt the natural air flow, there are no riser walls, no lofts or second stories. Floor space is not chewed up by halls. Rebuilding with an air-crete dome after a natural disaster will require far less time than conventional construction.

With over over 70 million refugees in the world today, this do-it-yourself dome can mobilize their greatest asset: a willing labor pool. Working together to build their own homes, refugees can quickly transform ramshackle camps into livable settlements.

Whatever the context, building homes among friends and neighbors creates a unique sense of place and of community. The domes can serve many purposes including classrooms, clinics, chapels, stores, inns, etc.

A single set of plywood molds can be used to construct many domes. Extremely strong, stable and eco-friendly, the DIY Air-Crete dome offers accessible technology for those who wish to assemble their own homes, live a simpler, sustainable life style, and enjoy greater financial freedom.

Aso Farm Land's Styrofoam dome hotel in Kyushu Japan is a good example of possibilities for a community of domes. Nowadays, 15 years after its inception, the Japan Dome House Co. This 'igloo' style dome is inspired by the sea urchin. Make a free website with Yola. Home About. Self build for a tiny fraction of the cost ofconventional construction using 17plywood forms. Small scale cardboard model, and building brick of shredded paper and rice glue. Creative solution captures dead space for storage.
