In The latest list of Aircrete compression tests, carried out in 2024, batches with higher percentages of foam* working with Domegaia’s mixing approach continuously resulted in collapse. There are two probable factors for this: decision of foaming agent and the dimensions from the mixer.
Much more detailed research of Stabilized Earth and willpower of its compressive strength is needed, as You will find a expertise hole and insufficient details for this building material.
The sodium silicate and NaOH were combined together for 3 minutes then mixed with fly ash for an additional 5 minutes. Once the geopolymer paste was homogeneous, the foam was additional and blended for another five minutes right before it was put inside the fifty-mm mould.
Lightweight: Cuts down the entire excess weight of your concrete, making it less complex to control and appropriate for programs calling for lessened structural load.
The objective of testing Aircrete is to obtain info and familiarity with Aircrete’s compression strength and Review the effects to that of concrete. We've been looking into aircrete as a attainable alternate to the current earthbag construction options for your Earthbag Village (Pod one). At the time this compression screening is completed, we plan to operate a crowdfunding campaign to match labor, expenditures, And just how effectively the structures perform facet-by-facet.
Within the 20-third trial, the Domegaia strategy with the previous a few trials was repeated as a result of constant success. However, in this demo, the cement mixer was replaced with The hand held drill mixer. Within a seven gallon bucket, 19.03 lbs of cement blend and 7.six pounds of water were being combined. This slurry was blended With all the drill, then foam was added to the highest and mixed yet again until finally everything was uniformly merged.
It is extremely vital that you put on proper air entrainment agent protection products when working with concrete. The dust is risky to the eyes and lungs. Because of this, it's important to thoroughly cleanse up remaining dust also.
Provided the conclusions from this 1-year extensive experimental period, Aircrete nevertheless has possible and some variables must be investigated even further, as outlined previously mentioned, prior to solidifying the tips on how applicable Aircrete is structurally or for use as insulation.
4 lbs .. Only the lightest cylinder collapsed, probable as it contained one of the most foam. The suspected concern with Trials three and 4 was the mixing. It was assumed the cement and foam required to be homogenized, leading to diverse foam contents and weights across the 3 cylinders. Also, the lids confirmed no apparent effect on the method.
The previous set of trials (joined below) did not produce consistent success, but there have been nevertheless numerous effective checks that furnished practical details. Down below, we share the most important/helpful of such.
The Aircrete mixes ordinarily provided different foam-to-cement ratios, when the Handle used a standard concrete mixture. These recipes were being created to test how various the foam content afflicted the compressive strength on the materials.
During the thirtieth trial, Trial 29 was recurring, however the slurry and foam ended up each combined within the concrete mixer in lieu of the bucket straight.
You'll find restrictions that foam concrete is thought to possess in thought on the plethora of benefits:
Both equally the cement slurry and foam were blended within a 7 gallon bucket While using the drill mixer. This demo was a hit as Not one of the cylinders collapsed.
