Harry, on my double paddle mixer, I cut each shaft in half and welded same size hex bar extensions in place. This brings the drill motor above the top of the 55 gallon drum.
I just wanted you to know that I went to Northern Tools and picked up a double paddle mixer. I had almost bought the other double paddle until I saw this video
Harry another great content video. Thanks for sharing. I finally got to make a batch with your thickening agent and it worked great. My water is a little hard but not terrible. I used my water with the batch. I have also been experimenting with just portland and EPS with no foam and getting some strong mixes 1 part cement, 8 parts EPS). I am also trying adding powder organic lime as a filler aggregate and substituting half of the cement. Also really good results. I will share when I get further along.

Harry, can you tell me what is the maximum insulating mix ratio that would fill the inside of cinder blocks eight inch thick eight feet tall ??? Would adding styrofoam mixed into aircrete exceed the insulating rating of just aircrete ??? Thank you for your help Sir Harry. Peace VF
If the blades are switchable from side to side then the currently "mix down" one could be made to mix up... so I guess that the blades are not switchable - right?
Harry, You just keep innovating! The thickening agent is very interesting. I make aircrete flue blocks for outdoor fireplace chimneys. The down side is that the flue block is fairly soft. It appears that your thickener may be the ingredient I need to provide the structural support I'm looking for. Look for my order. Thank you! Val
Thanks for answering my question If the thickener can be used with styrocrete. Next question. How much thickener do I need for each batch of styrocrete or Aircrete. Looking forward to the answer and can you send the thickener to the Philippines?
Loved these Lessons ;+) and appreciate your channel. ... Obtained a Double Paddle Mixer (Klutch brand) a while back, to be ready for Aircrete mixing, but looking at direction of my paddles moving; ... at center of two paddles in opposite rotations, my mixer would be pushing a slurry mix downward; and I want to change that to pulling the slurry upwards; like you say is better; as in pulling heavier cement slurry up into added foam. Questions: Is it the center between the two paddles ... the source of direction you are talking about? ... If so, I notice if I put Right paddle in Left position, and Left paddle in Right; That gets the middle of paddles pulling upward; but the threads on paddle end clamps are reversed (won't screw clamp to power head). ...

Does that seem like a worthy idea to get the Upwards Paddle movement? Anyone tried that yet ? ... I ordered your thickener after watching this clip. Thanks and Happy Days from Bill in Northern California ;+)
I'm very surprised by the requests and questions... it's all on the Internet if you just search and read... aircrete (foamed concrete) has been used in Europe for 70 years... look further than around your town...
You’re probably thinking of autoclaved aircrete. That’s a different process by using aluminum which chemically releases hydrogen and forms bubbles in the mix. Requires cooking (autoclave). End product is similar but getting there taking a different route.
I want to order the thickening agent, but I don’t see a description that explains how much is used for each batch. Nor do I know when or how to add it to the mix. This is necessary information in order for me to know how much to purchase. Can that information be made available on the shop or website somewhere please?
Have you talked to the guy who runs the spacecrete channel? He has a thickener that results in a zero slump cement that I would like to see used in tandem with a foaming agent. If it works, aircrete could be 3d printed.

Harry, have you tried using Graphene or hemp materials to enhance the structural strength? Graphene-enhanced concrete is tested and it provides a 146% increase in compressive strength, a 70% increase in flexural strength, and a 400% decrease in permeability. The incorporation of graphene in concrete would develop structures with increased durability, an increased conductivity, and thermal properties. Resulting in an overall decrease in CO2 emissions. Hemp concrete or hemp lime, it's a biocomposite made from a mix of the woody core of the hemp plant, lime binder, and water. The hemp core (also hemp hurd or shiv) has a high silica content that allows it to strongly bind with the lime.. As a result, you get a lightweight, cementitious material with good high insulation properties that weighs six to eight times less than concrete. It's ability to aborb CO2 emissions actually make it a carbon negative product. Because of the high moisture content care must be taken in the drying or curing of hemp, unless your intention is to make hemp graphene. At this time hemp is available in moderate amounts except for industrial or textile use and is utilized in a variety of products from clothing and shoes to bulletproof vests, car parts, artesian niche soaps, oils, beauty and health products. For hundreds of years it has been available as rope for maritime travel in boats and netting. Hemp as a means of paper and due to it's strength even the paper is utilzed to make implements, dishes, cups and musical instruments. Aircrete is simply cement with bubbles., there is no set formula. Fine foam, which has a high density, can be added to increase aerated concrete's strength, which results in a stronger aircrete. When high densities of foam are included, aircrete can become brittle, and chipping can occur. This type of aircrete will have limited compressive strength and could not be load-bearing.Aircrete offers many traditional concrete benefits with added properties to enhance sustainable and energy-efficient homes. Aircrete offers superior insulation properties due to foam and air bubbles built into concrete itself which can be enhanced by adding various types of polystyrene or polyurethane foams improving it's insulation values.Aircrete is most often used for exterior and interior walls. However, aircrete can also be used for several other home applications, such as precast blocks and panels and concrete slabs for an insulated flooring system. In some cases aircrete is used for poured roofs, increasing insulation capacity of ceilings and attics where heat tends to escape from homes. When used with additives it's load bearing capabiities, compressive strength, durabilities and other characteristics are greatly enhanced. Graphene can be made from just about anything - including sugar, so it's cheap & affordable. Hemp is becoming more readily available and can be purchased in a variety of forms as I described earlier.
Very interesting. Have you ever imagined a machine that would continously produce aircrete that could be pumped from a long fat tube. If this could be done, and mounted on a big truck then that would be a very good business for someone to take to projects, the client then only needs to concentrate on the form work
Dome Gaia had such a machine for sale or in development but I don’t think it is still offered. There must be a reason… they make a lot of aircrete domes (brick igloo approach).
@@chaosplan I have seen their work, is suitable for the warmer climates only. If someone made a machine they may as well make large flat blocks on floor molds and ship them off in their spare time. People get a concrete truck to come and pour for a slab or whatever, so it should be feasible for aircrete to be ordered in the same way, its just about it penetrating into the market
It would have to be a “mix on site” machine. Driving and wait times I think would let the foam collapse. So maybe a trailer set up. Order a pallet of cement bags for delivery, bring the trailer and other ingredients, mix and pump. The trailer might need a couple of channels for water, depending on the on site water - A filter and a softener - use one or both as needed.
WELCOME Terence! Appreciate You 👍 👍 Absolutely agree with you! So many Benefits! Our Customer who is now a Dear Friend is building a Great Dome in Australia right now - applying my technique. We have been receiving great updates on the process, it looks GREAT!
I just found your channel and been watching , excellent videos . Silly question : couldn't you just resin coat outside edges to strength (not structural strength) insulating blocks ?
8:40 you should be able to swap the stirrers to change the pulling a pushing, upward pulling would be more efficient because you are letting gravity to help you, but very tiring if if is solid concrete or other heavy mixes
My Klutch brand double paddles won't swap because the L and R paddles fit the L and R marked side of power head only, ... each has a different thread clamp direction (one clockwise, the other counter clockwise)! Maybe this is ok anyway: my double paddle pushes slurry downward in the middle, while the outer edges push the slurry upwards. Maybe that is best configuration, and I was brainstorming about a fix option that I do not need.
Another quality video. I appreciate the tests. I'm scratching my head a little over the randomness of the values though. The variances in pressure and depth, in a random sort of manner. And both columns turned out with more variances than i would have expected. So now im wondering if it's inconsistencies in the mixing process. Or, is it because of the vertical pressure causing partial collapses in sections. I'll scratch my head for a while and check back with you. (I have been watching for years, but somewhere along the way i got unsubbed somehow. So I've missed a lot.)
Could be a shade and difference in t° and curing speed. Could be a mixing issue. Or it could be lack of uniform filling due to how foam fills the space. For concrete one would use the vibration to make it fill all gaps; can’t do it with aircrete as that would start bringing bubbles to the top. Probably best to start by taking multiple samples of ready to pour aircrete (from same batch) to check for possible mixing issues. Agree - good video. Getting closer and closer to science.

I was just thinking about put s fireplace and chimney in my building. I was starting to contemplate how to do it.
What size fireplace were you thinking about?
@@stonecreekmasonry9282 I guess if I said the standard residential size that would sound bad
It's not about "bad", it's about what size you need to heat the area. A stand size fireplace is 36" wide x 25" tall.

What is your em@il?
Do you need the thickening agent for four inches or less height in a pour?
Use it every time you make a batch of Aircrete 👍 👍
But is it necessary if you are not going higher than four inches?
@@docvencil2222 That is what I do & Recommend. What you decide to do is up to you.

You should cut a 2 foot piece off of each pillar and weigh each one so we know what the strength to weight ratio is for each of those 2 mixes
The deeper the liquid is the greater the pressure, that the pressure at the bottom will always be greater.
I wonder if it would change the strength if the water wouldn't have leaked out the bottom?
The strength would have not been any different.
I've read or seen where they add like little metal shavings to give it more rigidity. Have you heard or seen this?
Generally sand or shavings sink through the foam if the foams light or cause it to collapse a lot
As far as Aircrete I would Recommend fine PVA fibers.
