You should Be aware that making your own private foaming agent from scratch requires expertise in chemical formulations and could not yield exactly the same results as industrial products. It is often recommended to utilize a commercially readily available foaming agent that's been tested and optimized for use in concrete.
Welcome into the Aircrete Engineering open supply engineering hub. The goal of this site is usually to share the engineering actions, study, methods, and resources we’ve used to validate the protection of our Aircrete designs and structures.
Seeking earlier the dear successes in these past trial operates (located in this article), You can find Considerably to be acquired from unsuccessful assessments. Even though the final results were not perfectly reliable, equally the scrapped Concepts and variables analyzed are still pretty valuable.
Below we examine our engineering results and the procedure we used to obtain the outcome we did. We also share ways to use the various spreadsheets we produced.
A: Indeed, in Demo 21, rising the Drexel concentration from four oz to six oz while in the foam Resolution led on the manufacture of a longer-Long lasting, improved-good quality foam. Due to this fact, the Aircrete did not collapse, indicating that a far more concentrated foam Option can enrich Aircrete balance.
Q: What difficulties had been recurring through the entire undertaking that needed to be enhanced or thoroughly checked?
Natural environment Helpful: Just as other option concrete materials, foam concrete is a lot more eco-friendly since it consists partially of recycled materials and demands considerably less Strength for its manufacturing.
Trial 16 was the 3rd profitable demo, even though it wasn’t a normal mixing trial. Demo sixteen evaluated the integrity of foam produced with different makes of dish soap and Drexel.
While in the forty-eighth demo, the Aircrete Harry mixing method was followed, but 5% extra concrete was used and stucco reinforcement was extra. six cylinders had been manufactured once the demo was repeated.

The Aircrete mixes commonly provided unique foam-to-cement ratios, whilst the Command used a standard concrete combination. These recipes have been intended to examination how varying the foam content material affected the compressive strength of your materials.
mixes with probably the most evidence is that the standard foaming agent used by Domegaia, 7th Technology Dish Cleaning soap, could be the batch’s central challenge. All superplasticizer in concrete kinds of other Aircrete mixing techniques use Drexel as the foaming agent, and trials that substituted seventh Generation Dish Soap for Drexel although following the rest of Domegaia’s common treatment succeeded.
Workability: The convenience with which foam concrete could be combined and molded into a variety of designs allows it to serve a myriad of reasons and apps in the construction industry.
Should the slump is simply too high (collapsed slump): Incorporate a lot more dry concrete mix in small parts and remix to thicken the combination right up until the desired regularity is obtained.
