All in all, this round of Aircrete screening was profitable in building upon the final results of previous volunteer teams. The past workforce finished with normally inconsistent effects, but their successes and noteworthy faults remaining a stable foundation For brand new trials. This most recent testing highlighted the trustworthy accomplishment of Aircrete Harry’s mixing system in comparison with Domegaia’s, predominantly a results of the foaming agents used and goal foam densities of the two techniques (a reduced foam density, of close to sixty eight g/qt, paired with Drexel was excellent).
Welcome to the Aircrete Engineering open up source engineering hub. The objective of this web page should be to share the engineering techniques, investigate, methods, and resources we’ve used to verify the security of our Aircrete styles and buildings.
This check of varying water hardness was only attempted as soon as, Therefore the influence of water good quality in these trials might have been far more apparent. Even so, corporations making use of Aircrete, like Domegaia, have had accomplishment only working with water from a hose.
What was created distinct early on was that online resources and recipes for developing Aircrete ended up scarce. Making use of them, we also discovered it not easy to deliver regular final results. This led to a prolonged process of demo and error, giving more details for future groups to construct on.
Though mixing, the foam shed some air and the final volume in the combination was lessen than typical. Only 2.5 cylinders ended up able to be stuffed. No compression assessments ended up conducted.
In the 20-third demo, the Domegaia technique within the previous a few trials was repeated as a consequence of regular achievement. Having said that, In this particular demo, the cement mixer was replaced with The hand held drill mixer. Inside a 7 gallon bucket, 19.03 lbs . of cement mix and 7.six lbs . of water had been blended. This slurry was blended With all the drill, then foam was included to the top and combined yet again till all the things was uniformly mixed.
Later tests also confirmed that our means of weighing and/or measuring foam in advance of mixing it in led to break down.
Higher Insulation: Foam Concrete gives thermal and acoustic insulation to ensure that a lot less Electricity and dollars are expended on insulation materials.
Regional adaptation isn’t optional—it’s existential. In Canada’s Yukon Territory, the place temperatures plunge to -forty°C, contractors mandate aircrete foaming agents blended with ethylene glycol-based antifreeze additives. These formulations prevent micro-cracking in the course of freeze-thaw cycles, a problem that Formerly caused seventeen% of discrete structures to fall short within just two a long time.
A formulated anionic surfactant that gives highly stable foam in low density lightweight cementitious formulations.
Lid has tube attached to The within (you don’t have to bother with the tube slipping out in the bucket)
The equipment is turned on with a foot pedal, making it much easier and faster to show on and off. The Little Dragon includes a individual change
The following trials demonstrated that Aircrete’s security is highly delicate to the combo ratio of foam and cement slurry. Heavier Aircrete recipes (higher cement content material) have been far more successful in averting collapse, although lighter mixes (higher foam written content) have been liable to failure. Furthermore, a chance to completely submerge the mixer during the slurry appears to get crucial for appropriate mixing and steadiness.
The consistency was based on time and coloration consistency of the combination. This was a restricting stage simply because a exam or parameter to correctly test even regularity of the fast curing concrete additives mix wasn't used to tell if a person Section of the mix is heavier than A further.
