    I would take that spreadsheet to the home depot's pro desk and ask them to run it through their bid room. Could save you up to 20% on materials. Usually the larger the order the bigger the discount ✌️ just a thought

      We have the pro discount, which at least pays for taxes and gives a discount on delivery. Some items get a bulk order discount, so that helps some.

    100% agree with you on your decision. Also with more conventional builds there's not the unknown factor of failed batches and that added cost. My first construction job was pouring foundations when I was 18...never fell in love with it. lol.

    • @RedandAprilOff-Grid
      @RedandAprilOff-Grid  3 ปีที่แล้ว +1

      Yes, I am sure we would have had some batches that settled, and we may have needed quite a few extra batches. We are pouring the slab ourselves a little at a time. It is a lot of work, but going well. We need to do something with the extra Portland cement. 😄

    No one needs more stress in their life. I’m so glad that you guys figured it all out and it’s actually going to cost 5% less! Red and Brian would get along great because Brian is all about crunching numbers and spreadsheets and research. It’s really cool to see the 3-D walk through. It’s going to be awesome! 😃❤️👍 Also. I love spiders. My son does too. He picks them up. Lol

      Yes, many things about using aircrete were definitely going to be stressful, & trying to keep the walls wet enough to cure with all of the wind we get in the spring.
      It's a challenge, we needed our walls to stay wet, and yours need to stay dry. 😂
      We think 🕷️ are pretty cool too, and I like seeing all the different types of tarantulas we have out here. The black widows that like to hang out under our trailer are not so cool.
      Thanks for watching.😊💜

    I think you saved a lot of people time and stress making this decision.
    That being said, comparing the two methods building a small (100 to 150 sq ft. structure ...think basic cabin--not house) in a tropical area,with only aircrete as structure and insulation,do you think the costs per would yield similar results ?

    • @RedandAprilOff-Grid
      @RedandAprilOff-Grid  ปีที่แล้ว

      If you already have the equipment to make aircrete, and build a dome shape, aircrete would be less expensive. A traditional structure could be built faster, would last longer, and likely wouldn't cost too much more. I have heard of multiple aircrete domes with water leaks that can't be repaired, because the aircrete near the cracks turns to powder.
      If you have some time, and want to build a structure that is inexpensive and strong, I would recommend hyperadobe. We just finished helping our son complete his hyperadobe tiny house.
      Best wishes! 🌞🏜️

      Yes, the coating is great as long as the aircrete doesn't turn to powder or small crumbs inside the walls. If we could have made consistent and good batches like at the beginning, we would have used aircrete. It's too cold here for now, and we would have had to wait until spring to do further testing.

      Awesome, glad to hear about people actually building structures out of aircrete. We haven't found many people online that are sharing the long term durability of aircrete. It would vary a lot too depend on the recipe and methods used. Yes, I think the cold Drexel and water were making for a wetter foam. It was still under 100 grams per quart, but heavier than our earlier more successful batches. We get a lot of wind in the spring, which would have made curing the aircrete walls a huge challenge, so we are glad we aren't going to have to deal with that.

    A sensible decision, and especially because of labor and constructability unknown unknowns, which will surely be a lot higher with aircrete. Often alternative method advocates are not so objective. But your materials-only cost comparison may not be representative for comparing just the ext walls. In any case we all expect you to be continuing with the aircrete testing experiments for the edification of your viewers - thank you!

      We will be plastering the rest of the aircrete garden wall, and eventually plan to use some of the sample blocks to make an outdoor rocket stove, and maybe a pizza oven. We may eventually make some more aircrete for a rocket mass heater for in the house. For now, we need to get this house built, and it's too cold to make aircrete.

      We probably have excellent soil for making adobe, it would be cool, but a whole lot of labor. Thermal mass is great in the summer since we cool down so much at night. We wouldn't technically freeze, but it would be really cold in the winter and hard to heat. That is the main reason we moved away from any type of earth type building.

      Yes, we are planning to do earth floors on the south side of the house, so we should get some thermal mass benefit. The sun will hit the floor in the winter, but the overhang is such, that it won't in the summer. Thinking about it now, I wish we had made room to make the floor thicker to make more use of that thermal mass. I had thought about adding a wall or something inside, to capture some of the heat, but we aren't sure yet.

    Since the low foam yielded best results, could the reason for the failures and cracking have been the amount of water? Depending on the foam used could have contained a significant amount of water that wasn't accounted for, maybe?? I'm completely new to aircrete, so assume what I'm throwing out here are just wild guesses with this stuff, but I'm not a stranger to concrete. I've been fascinated with it ever since I was a kid. The UHPC used in pre-cast pre-stressed beams last time I dug into a white paper used a significant amount of cement to aggregate ratio, roughly 1:1 and the aggregate is super fine, but the cement to water ratio is significantly reduced. Would almost be a dry pour if not for the add mixtures used. It really seems like yall were on the right track with the high cement ratio. Maybe one day this stuff will take off.. Just hoping someone doesn't figure out the secret and all of a sudden the price skyrockets up next to lumber... lol Seems to be the way things usually end up Anyways, cool vid bud. Still going through the playlist. Thanks for putting all this out there

    • @RedandAprilOff-Grid
      @RedandAprilOff-Grid  3 ปีที่แล้ว

      We are using a somewhat low water mix to make the aircrete stronger. The typical recipe that most seem to be using has 6 or sometimes even 7 gallons of water, and we were using 5 in all of our test samples. It makes it stronger, but I'm sure also less insulative. It also seems to make the slurry heavier which make it harder to get the heavy stuff at the bottom mixed in with the foam. If we had decided to move ahead with aircrete we probably would have bought a mortar mixer.
      Adding styrofoam to aircrete is all the rage now, I think it will have issues too, and will be a lot of work, but we'll see how it works out for people as they start trying to make stuff out of it. There has been a shortage of Portland cement in our area lately, probably due to shipping issues, so it seems like the price will go up on it.
      Aircrete is interesting stuff, and tricky to make. It's been an interesting experiment, but we are glad to be moving on. Now that lumber prices have gone down some, a more traditional house with more insulation than the aircrete house will be less expensive anyway. We have a video comparing the cost. 🙂🏠

    What state/climate zone is the house being buildt in again? R19 walls with R38 ceiling is pretty much lowest allowed by code in North Carolina. For a passive house You'd want at least an R60 roof! Add 3" of foam board to the roof to at least get R55. is my suggestion. Adding insulation latter after the build is always very costly and impractical. I'ts the most important part of a passive hosue build !

      We are in a desert area, climate zone 2/3. We don't expect the house to be fully passive, but the house should do really well in the winter with the large south facing windows. Swamp coolers work really well here for most of the summer, and our temperatures cool off enough at night, that we don't need overnight cooling.

    @bobjoatmon1993 3 ปีที่แล้ว

    Classic example of everybody being excited by alternative building methods but then reality slaps you in the face...
    The reason it's not used more is that it's HARD. There's the resistance of banks to loan on alternative if it ever goes up for resale and that insurance companies don't want to because they have NO idea of their liability so can't set rates.
    I'm still proceeding ahead with the stand up panels between the steel columns. My test pour where I poured 1" of regular concrete, let it sit for an hour then poured 4.5" of styrocrete on top (2x6 frame, 4 foot x 8 foot) and let it wet cure for almost a month (I got impatient and couldn't wait the full 30 days, haha) turned out great.
    Note - I stood it up on edge and shot it's hard face with a .38 and all it did was small craters, no visible cracks so I think it's tough enough. For as massive as it looks it's amazing how light it is. (It's heavy but MUCH lighter that as if it was solid concrete).
    Obviously a crane rental will be necessary to stand up all the premade panel sections in 'Assembly Day'.
