Browse Forums DIY, Home Maintenance & Repair 1 Nov 06, 2020 5:38 pm Recently discovered aircrete, friend says he uses it in under ground mining and can hit it with a sledge hammer. Have seen on YouTube people make half arse structures and one guy a decent shed ,wondering why it couldn't be used as a building material as I can pour light weight slabs easily, and use motor or methods to secure together and to the foundation. Apparently it's low labor, cheap, and a great insulator, so good, that you might not even need to use insulation. I want to pour a concrete slab and build all the walls out of aircrete and erect them, and then make a roof and all the rest of it doors and windows ect.

Assuming you want to build with squares like this https://youtu.be/7KHEj3-KpHk But take this video for instance, https://youtu.be/_QQVmZ3UYxk It's like they didn't put much effort into it and it's more of a decent proto type but circle design could be alot more stronger in cyclone regions which I am, Re: Anyone see any Aircrete in Australia? 5Nov 06, 2020 8:34 pm chippy Hebel. Aircrete is aerated concrete, so is Hebel. Check them links out please and tell me what you think if aircrete panels, I bet they are alot cheaper per square meter by a long shot Re: Anyone see any Aircrete in Australia? 7Nov 06, 2020 10:11 pm It might sound faster on labour when comparing to Hebel blocks/AAC adhesive approach, but you would need: 1) Find structural engineer as well as PCA who will be able to certify this type of construction for you, but before you would to locate concrete supply company to prepare right aircrete mix for you. How many of them do you know who will be able to deliver and certify such mix? Considering you are talking about structural mix for the walls, the mix would have to be pre-tested for compression strength, etc. It won't be cheap, I don't think it will any cheaper than standard cement mix, e.g. expect it to cost $250+ per m3, so roughly $65+ for 250 mm wall. 2) You would need prepare and set up formwork for your walls, it will require skills in formwork carpentry, as framework would have to be also set up and aligned to levels, wall width, your building envelope, etc. Full size removable custom formwork for walls won't be cheap, too, as it will require to be done from structural laminated LVL and reinforced with several belts of rigid planks, generally attached together with type of special removable framework ties. In addition, you would need to install reinforcement for lintels, steel reinforcement to support top plate, etc. as those would probably have to be done from normal concrete and won't be cheap either. I would estimate you would pay at least $50 per sqm of wall for formwork, lintels, etc, but most probably much more than that. 3) You would need to order concrete pump to pour walls for you, manually mixing and pouring with buckets will be very labour consuming process. Pump for your pour will be costing you $1,500+. 4) You would need your engineer and PCA to certify that mix and application of technology was right and required properties were achieved. This will be another $5k at least. If anything of the above goes wrong (e.g. concrete blow up occurs due to formwork defects, wrong mix, etc.), you will lose the money and would have to manually remove and redo whole thing again. In addition to that, you would need to decide how you are planning to handle connections/communications, internal finishes, etc. as simply pouring the walls is far from being end of a story. Hebel blocks, on the other side, are 500x250x300, so when comparing to brick veneer, with one block you replace around 0.15 sqm of supply and install of framing + 0.15 sqm of insulation + around 8 traditional bricks, they are already certified and laying them right only requires a bit of a training and can be done under supervision of an experienced block layer. You would need to use special AAC adhesive glue instead of traditional mortar, though. In addition, your house would have to be rendered from the outside and ideally from the inside too to protect AAC as it will be sucking a lot of water from the outside as well as from the ground. And you won't be able to use just standard sand cement render for AAC, it would have to be rendered with more expensive mineral or acrylic or silicate/silicon renders. So all-in, you are still talking about $180-$200 per sqm for the wall made of Hebel blocks (without internal finishes) even if you are planning to lay them by yourself. You will end up with similar or even higher costs if you decide to pour aircrete but the risks that something goes wrong will certainly be higher with the poured AAC and I do not really how and who will be certifying it for you. Remember, they currently CSR builds AAC/Hebel blocks and panels at their proprietary plants which involve a lot of processes and high degree of quality control in order to get them certified as structural component.
