How To Make Aircrete Foam With A Shop Vac | Part 2

[@catgynt9148]

Another interesting variation on a theme... not a mistake, just an iterative step in refining a process. thanks for adding a glove to your safety gear, Tom. Wishing you and your family a blessed week. Peace brother

[@danielculpepper8772]

Love the fiddling hands on approach. Learn by doing. Mistakes are how we learn. Thanks!

[@GreenShortzDIY]

The process is just as important as the final product. Most of what we see these days is someones "polished" best. Thank you for watching.

Aircrete foam with a shop vac! Great video 👍🏼

[@GregsGarage]

It's interesting to see how different pressure sources affect the quality of the foam coming out of your Foam Cannon. I would be interested to see the break out strength of different aircrete samples using different densities of foam... Can't wait to see the next iteration and the improvements to the design.

A great video as usual! I love how you show the process of what you learn along the way. Copy those clips of " the train is here " and put them altogether at some point!

[@GreenShortzDIY]

Hi Ema. Thank you for the encouragement. The “trains here” compilation would be hilarious. :-)

[@andrefontes4473]

Parabéns pelo experimento. Te acompanho aqui do Brasil e vejo a sua evolução.

there is a Concrete HARDNER that can be Painted or sprayed on or trowel on outside of AIRCRETE to strengthen the Surface of AIRCRETE & also could add FIBERGLASS fibers concrete additive or Basalt concrete fibers /strings additive to add 20%/35% more strength to AIRCRETE

[@GreenShortzDIY]

Excellent. Thank you.

@TEXAS_FREE_STATE. Friend, I write this under correction. Sure I saw some info regarding homemade waterglass liquid made from ordinary cat litter. Amount added to water per batch of aircrete was 10% by volume of water, added at the final stage of batch mixing before pouring. Apparently also adds strength to finished product and adds moisture proofing qualities to cured final product. Hope I have the facts right.

If you 3d print some spheres with lots of smaller spheres inside each other then it will create more area for the foam to mix. The car wash foamers do it this way.

[@TheArtisanbard]

Wonder what happens if you flip ends of the diffuser pipe? Curious

[@cautobank]

Nice Try, I think last try, two years back was better than this. Still i think instead of using cleaning unit, it would be more better result by using compressor. thanks for your video, This is Chavan from India.

Wouldn't it be useful to get natural CO2 into a mix, or would that be to acidic in contact with water? How about nitrogen, is there a natural way to get that out of the mixture (ammonia, isn't that even caustic, to match the concrete pH)?

[@grilsegrils9330]

Maybe ozone + ammonia+ magnesium copper? "Ozone has been widely used in water treatment of various types of water. It can react quickly with organic pollutants, containing double bonds, aromatic groups, or amino groups [4]. In addition, ozone decomposes and generates hydroxyl radicals (•OH) in water. Hydroxyl radicals were considered to be the strongest oxidant in water and enhance the oxidation ability during ozonation [5]. However, ozonation for ammonia removal was regarded to have several deficiencies. First of all, ammonia mainly exists in the form of NH4+ under neutral conditions which were proved to have little reactivity with O3 and •OH [6], [7]. To improve ammonia removal performance, pH has to be maintained above 9.0 or higher during the ozonation process. Furthermore, the ozonation product is mostly nitrate. It means that the ozonation of ammonia requires alkaline conditions, and the total nitrogen removal efficiency is extremely low. In addition, the products formed by ozonation of ammonia nitrogen contain H+ ions, causing the acidification of the solution. For example, Khuntia [8] reported ammonia removal by ozone microbubbles and the oxidation rate of ammonia decreased obviously due to solution acidification as the reaction progressed. Therefore, the altered pH would lower the reaction process and make the mechanism more confusing to be declared. In order to improve the performance of above chemical oxidation reactions for ammonia (as well as total nitrogen) removal, some catalysts naturally come into people's vision. Ichikawa [9] reported that Co3O4 showed high selectivity to gaseous products. Chen [10] synthesized a series of catalysts with various MgO-Co3O4 molar ratios. And the highest catalytic performance at the Mg-Co mole ratio of 8:2 was detected, which removed 85.2% ammonia in 2 h and the proportion of gaseous nitrogen in the product was 44.8%. Liu modified NiO by surfactants [11], [12], which showed high catalytic activity and about 76% ammonia was claimed to convert to gaseous nitrogen. However, solution acidification inevitably occurred in all the above catalytic processes and resulting a series of complex changes in the types of oxidants and the existing forms of ammonia. No buffer was used to control pH in the above studies since common buffer components such as phosphate and carbonate were thought to have high affinity towards certain active catalytic sites that might block catalytic centers and work as poisons of catalysts [13]. The problem is that the heterogeneous catalytic system is too complex since it is difficult to distinguish whether the disturbance of reaction rate was caused by the change of pH or the interaction between catalytic and substrates. Moreover, catalysts involvement and declined pH during ozonation complexly altered oxidant forms involved, which made it more challenging to elucidate the mechanism of ammonia ozonation. Hence, although several so-called high-performance catalysts were reported, proper mechanisms involved in the degradation process of ammonia by ozone still lagged far behind ozonation utility."

When is Franken V.3?

[@GreenShortzDIY]

I need to do a Franken V.3.

Hey man, I'm not sure if you are aware of public auction websites but I use the public surplus website for a lot of things I can't find at thrift stores. These are all kinds of items including vehicles from government entities like schools, libraries, police, etc. The public needs to buy more of these items because they were already paid for with tax payer money usually, they are dirt cheap (seriously, I got 8 chairs for $50 total that when bought new from the city cost $4000 each!), and if we don't buy these items that are still in working order or can be used, they throw the stuff away! When I bought the chairs I mentioned, the employee was desperately trying to find someone to take two brand new beds (still in the package and made by the same company who made the chairs so those beds were over $8k each when the city bought them). No one bid on them when they were listed on the auction website and she was not allowed to relist them so they were going to the landfill! What a complete waste!

[@GreenShortzDIY]

Great tip! And it’s pretty amazing the waste in government. Thanks for watching.

[@xtcarlos]

Not sure if possible but I think it would be cool if you made the outside of the diffuser some kind of transparent pipe to see it working from outside... you know... for science.🤷‍♂️

[@GreenShortzDIY]

Cool. I need to try that. Thank you for the suggestion.

[@bullithedjames937]

1st🎉

[@GreenShortzDIY]

I only expect the best from you, James. :-)

[@TEXAS_FREE_STATE]

order some DREXEL FM160 from RUAL KING store I found another person video talked about it at $30.00 per gallon....

[@GreenShortzDIY]

I’ve heard Aircrete Harry mention Drexel. Thank you for the reminder.
