The Dragon XL's capacity to make small or substantial batches of Aircrete has made it the go-to foam generator for our workshop instructors and pro builders worldwide. It comes thoroughly assembled. Connect the Dragon XL to the foaming agent bin and begin making Aircrete!
A4: Storage need to be dry and cool, as porosity amounts may perhaps lessen Should the atmosphere is moist and incredibly hot. Low temperatures guarantee surfactants do not degrade and preserve efficiency. The storage space must be protected from immediate sunlight publicity.
A major concern While using the Domegaia technique arose from the choice of foaming agent. The exams unveiled that when higher percentages of foam were being used with Domegaia’s method and 7th Generation Dish Soap, the Aircrete constantly collapsed. This situation was mitigated when Drexel, a far more steady foaming agent, was used in its place.
In the final tests stage, extra compression exams ended up performed with the Aircrete Harry mix than with Domegaia’s, typically a result of the inconsistency in results observed with Domegaia’s mixes as well as their high humidity material. As well as standard Aircrete Harry and Domegaia mixing approaches, stucco reinforcement was additional to many of Aircrete Harry’s cylinders and Domegaia’s treatment was recurring utilizing Drexel.
The agent will have to go well with the specific cement used during the concrete. Some agents get the job done greater with particular cements, such as Portland or fly ash blends, than Some others.
Additionally, the Aircrete cylinders had better variability in their pounds than concrete cylinders, as shown in the plot underneath:
Demo 21 was the fourth successful demo. The foam composite steel During this take a look at was designed that has a higher dose of Drexel, 6 oz as an alternative to the advisable 4 oz. As a result, the foam was significantly more powerful, revealing that higher doses of foaming agent can enhance foam high quality.
So does tricky water with high metal articles, mainly because it reacts with surfactants to type precipitates. Even Organic growth like microorganisms and algae in stagnant water can affect the surfactants. Uncontrolled environmental problems also lead to new agents' degradation or evaporation.
This graphic compares the worry load and bodyweight just after curing for three unique mix procedures: Aircrete Harry, Domegaia, and Domegaia with Drexel. The mixing technique can significantly effects the material’s efficiency. This comparison reveals that Aircrete Harry outperforms the Other individuals in compressive strength, when the other approaches are lighter but weaker.
5. Fly ash is extra, at level of upto a hundred% of the OPC material, to reinforce workability and maximize prolonged-time period strength of foamed concrete. As a result of bigger surface spot of OPC/FA mixes have a better water demand from customers than OPC/sand mixes.
Regardless of these difficulties, the group overcame some concerns by switching to Drexel since the foaming agent and thoroughly controlling mixing occasions. Nonetheless, the limitations of utilizing small batches and non-industrial equipment mean that the results do not absolutely reflect the effectiveness of Aircrete in greater-scale construction.
This downscaling probable brought about uneven foam distribution and enhanced foam collapse, as scaled-down mixers don’t inject the foam into the bottom of the mix like the Dragon XL and may not Mix the materials as persistently.
Cement foaming agent, often called foaming concrete foaming agent, refers to an admixture that can reduce the surface area tension of liquid and make a large amount of uniform and steady foam with the production of foamed concrete.
The Domegaia Building system has long been pioneered to work with easy applications and materials. For foaming agents, we have used dish detergent because it's out there around the globe, and this continue to will work.
