In The latest list of Aircrete compression assessments, conducted in 2024, batches with higher percentages of foam* using Domegaia’s mixing approach continuously resulted in collapse. There are two very likely reasons for this: decision of foaming agent and the size from the mixer.
Once again, the benefits that foam concrete has about standard concrete are many. Between the significant Positive aspects are:
This test of different water hardness was only attempted once, Therefore the impact of water top quality in these trials might have been extra evident. On the other hand, providers employing Aircrete, like Domegaia, have experienced good results just working with water from the hose.
What was made very clear early on was that online sources and recipes for creating Aircrete were scarce. Making use of them, we also observed it not easy to crank out regular effects. This brought about a prolonged technique of demo and mistake, furnishing more info for potential groups to build on.
After the dry materials are combined with the foam, water is internally included to activate the cement and start the concrete forming course of action. The air pockets are produced because of the foam in the mixture, and As a result lightweight foam concrete is generated.
Detailed benefits can be found right here. In summary, foam produced with Suave dish cleaning soap held its volume best and Drexel drastically outperformed 7th Technology Dish Soap in a very one-on-a person take a look at.
Foam sort concrete is definitely the development of foam concrete with foam as one of the primary additives to provide air pockets inside the mixture.
When mixing Aircrete at home, it is useful to take into account seemingly moment variables like these if faced with regular failure. In addition to these modest resources of mistake, the earlier list of Aircrete trials disclosed redispersible polymer powder uses that the foaming agent advised by Domegaia could be unreliable.
4 lbs .. Just the lightest cylinder collapsed, very likely as it contained by far the most foam. The suspected challenge with Trials three and 4 was the mixing. It had been assumed the cement and foam necessary to be homogenized, leading to different foam contents and weights through the 3 cylinders. Also, the lids showed no apparent impact on the method.
High moisture content material was another major craze with these Aircrete samples, specifically in high-foam mixtures. Some proposed fixes ended up for a longer time curing times or out of doors curing.

Formerly, safety issues more than concrete foaming agents were often about environmental impact and human health.
A: Domegaia Minor Dragon and Aircrete Harry foam generators, each machines executed equally, even so the Aircrete Harry generator taken care of foam quantity a little superior, displaying 1 cm fewer collapse following the 75-moment mark. This indicated the Aircrete Harry generator made much more secure foam eventually.
When the slump is simply too high (collapsed slump): Add extra dry concrete combine in smaller parts and remix to thicken the combination until finally the specified consistency is obtained.
