In The newest set of Aircrete compression assessments, done in 2024, batches with increased percentages of foam* utilizing Domegaia’s mixing process continually resulted in collapse. There are two probable reasons for this: decision of foaming agent and the dimensions on the mixer.
Every single challenge stemmed with the machines, materials, or techniques used in different trials, pointing to the necessity for standardization and refinement while in the Aircrete approach.
Addage Foaming Agent CLC-FA (Synthetic based) when combined with water generates a stiff white foam and boosts the volume from the compound by twenty to 25 instances. This foaming agent could be mixed with any sort of Portland cement, and used for various functions.
3 unique mixer kinds ended up used: the egg beater drill attachment, cement mixer, and auger drill attachment. The egg beater was carried out following the auger was used for three failed trials. The key contribution from the egg beater was a faster mixing time, though the trial it absolutely was used in nevertheless unsuccessful. The a lot quicker mixing led the Aircrete to be overmixed or perhaps the foam bubbles to become overwhelmed out.
The distinctive Qualities of foam concrete undoubtedly are a results of its composition as well as introduction of air voids throughout the combination. These Attributes permit a wide software of foam concrete. Some important properties are as follows.

A low p.c deviation displays that in one combine, the cylinder weights have been constant in relation to one another.
Aircrete has the probable to get a cheap, lightweight, and easily obtainable building material. Open up sourcing this Aircrete analysis is very important to ensure these processes can be replicated and so other engineers or builders can improve on our perform, creating a much better base of Aircrete know-how for everyone.
From the twenty-seventh demo, both equally the slurry and foam have been mixed inside a five gallon bucket in place of a 7 gallon bucket. Other than this, the identical technique within the previous two trials was adopted.
The fluid character of foamed concrete lets the concrete to free stream into even the smallest of spaces making it highly ideal for void fill programs. Foam concrete also reveals no settlement properties that may happen with granular fill materials permitting a much more secure fill.
Aircrete commences being a malleable slurry, but hardens rapidly and really should not be poured down drains because of the concrete involved. It's best to dispose of Aircrete in its hardened point out, then the stable particles is often disposed of in a typical trash bin.
The heaviest Aircrete was the strongest, but nonetheless Substantially decrease than common concrete (600 psi vs . 4100 psi, respectively). A different noteworthy observation was that the light and conventional mixes weren't entirely drying while in the cylinders when it was time with the compression exam, even soon after 28 days. When it absolutely was time to remove them within the cylinders, water would rush out and since of that, the cylinders had been continue to moist.
Be aware: Common Aircrete batches are Typically much bigger than our test batches and This may improve final results by reducing significant bubble build ups and supplying more publicity for evaporation to manifest.
From the forty-fourth trial, Aircrete Harry’s regular mixing method (from Demo 38) was followed, but stucco mesh fiber was added to your walls on the Aircrete cylinders. This trial was steel composite panel also recurring to create 6 cylinders.
