Some advice from a man who was a brick layer for 20 years. Add some sand, perhaps; 5 styro, 1 cement and 1 sand. This will give your bricks more strength and make the finish smoother. As has been mentioned already, a better mould (form work) will make a better job, I suggest a metal box, maybe 1.2 millimeter steel (1/8th inch American) with a base of the same material. Your big mistake is removing the bricks from the form work too soon (Far too soon) If you coat (paint) the inside of your form work with old cooking oil, then leave the bricks to dry till the next day, you can just bang them out upside down. Lastly, you will not be able to build occupation rated buildings. (ie: places where people will live or sleep) Building bricks must have by law a 2 hour fire rating. They must withstand a fire for 2 hours minimum before they disintegrate. Your bricks will not only burn quickly, they will intensify the fire and release poisonous fumes. But, garden planters, garden beds, garden borders etc, I think you have a great idea for any non fireproof building...

Makes no difference, a brick chimney (not the actual fireplace) could be surrounded by drywall or render or whatever you like, the bricks (and that's each individual brick) must sustain 2 hours of fire. (Fireplace bricks are made from a different material ie: fire clay) This construction ruling is for Australia however, so I would check with your local 'officials' if your not here in the Great Southern Land....

Toob247 - You can't safely pack your hollow walls with this ordinary white Expanded Polystyrene EPS, as insulation. Blue "Styrofoam" (brand name), Closed Cell Extruded Polystyrene XPS, is used, and it is safe and fire rated. Only in the USA and Canada do they call both of these products by the same name Styrofoam, they are totally different products. Note that one is Expanded and the other is Extruded. I see in another post that you are filling your walls with this White Polystyrene and Pour in Foam. This compromises your electrical wiring in that your wire size and current carrying capacity is designed around the assumption that the wiring is not totally enclosed. At high loads the wiring may overheat and set fire to the walls. Unless your pour in foam is sold for pouring into walls, it is also potentially unsafe to your general health. For example many of the industrial pour in foams contain toxic gases such as formaldehyde in the bubbles which slowly release over time. I suggest that you talk to your insurance company asap. In most western countries it is actually against the law to use EPS as house insulation. This video is poorly named in that it is about making bricks from Expanded Polystyrene EPS, and not Styrofoam XPS.

Agreed. We did have (25 years ago) here in Australia such 'styro' (pour-in-place) insulation but it was banned, even with added Borax it was still too 'inappropriate'. As I mentioned, such 'styro' bricks maybe ok for garden walls and such. Cheers...

Perhaps, there is still the toxic fumes issue if using it as an insulation. Here in Australia we banned such insulation at least 25-30 years ago.

One thing to consider, if you haven't already, is to build your forms using a better grade of material. If you use a smooth material, such as Melamine surfaced plywood, the forms will come off much easier and you won't get the broken corners like I saw in your video. Melamine came to mind but there are plenty of other choices. Perhaps lining your forms with plastic sheet or left over Formica sheets. By the way, I think the idea of styrofoam bricks is a good one.

moved your mixing tub at 1:15 into the catch position at the shredder. I saw you bag the fuzz, scoop the fuzz into buckets, then drop the buckets into the tub. That us a lot of work, instead of just dropping fuzz directly into the mix tub. To measure volume, do it systemically. Either weigh the foam pre chop, or Mark a line in the tub. Your volume will be uniform, and your work system reduces work activity, while producing uniform results.

Thank you. I will attempt to use this in a building and insulation at the same time.

Yours is a great idea that should hold up over time.I built a small post and beam shop in the woods behind my house in 1984. I used plastic packing beads, vermiculite, sand and Portland Cement as a light weight concrete to in fill the space between the timbers. This material has held up very well through all kinds of weather, rain, snow, and many freeze-thaw cycles with no signs of wear in all that time.

Great idea for decorative elements, blocks, bricks, small pots...

I was thinking to encase the styrofoam brick in a separate pure cement to have a neater, heavier, more robust brick that would hold up better to the elements and animals and such. Cool and informative indeed. Cheers.

50% silica type sand can help in binding and I have used this with a 5 (Styrofoam 2cm-)-4 (vermiculite 2cm-) --1(mortar-sand lime cement) for a trowel on mortar mix thick stucco (4" or 10cm) with a 9 gauge steel galvanized 10cm square backing panel, tin backside the maximum slump level was about 18" (40cm) with an open face. It sets well in a day and cures in 3. this mic can also be used to patch holes in formed concrete that has a roughed surface. over 86*F (34*C) I would recommend a plastic cover for a day. Probably could make bricks from this also, but the cure time would be a day before removal from the form.

very creative. great idea how to get rid of styrofoam.productive way.

Cool! It would be interesting to test the physical properties and experiment with mix ratios and additives such as fine aggregate (sand) and different kinds of natural or recycled fiber tensile reinforcement.

Few Suggestion. If there was a way to increase the size of styrofoam pieces to say 1/2" and adding of sand and more effort on mold can give good result. At the time of laying, if each brick is dipped in cement slurry with URP added, the resultant wall will be more safe for health.

Have always wanted to make my own tow behind papercrete shredder/mixer and thought that this styro scrap material would be an excellent addition ingredient to papercrete mixes.

These look like they'd crumble pretty easily with that much Styrofoam. It would probably help to add some chopped fiberglass strands, or even a small wire mesh insert in each block. Also, as already pointed out, cement needs some silicate material (sand) to form a strong cured material, and better molds with smooth sides would keep the blocks from getting torn up so much when you release them from the mold. I definitely like the idea of finding alternative uses for used Styrofoam though, it's one of the most wasteful items on the planet after it's served it's original purpose. Even just inserting a solid Styrofoam core inside the block might be a worthwhile experiment.

I love this concept for flotation. I would think you could coat a pontoon-sized section with something to keep it from disintegration in water and leaving a trail of pollution. Thanks for sharing!

During WW2 we made boats out of concrete. See "ferro-cement boats." I think it's better to have a very strong shell with hollow interior rather than a solid foam concrete, which would end up quite a bit heavier.

Just wondering, what if you added a bit of sand to the mixture? I imagine it would help the cement bond better and help the brick be quite a bit stronger. Also, it may help in the form making.

Thats actually a really good idea. Not sure how well they would stick together if your just using Portland cement powder, If I was doing this I would like to add some other binders such as sand and possibly a little bit of pea gravel. Will have to give this a try sometime.

Thank you

Since it is a lightweight material, perhaps it could be cast into larger flat panels, with some reinforcement like old fencing wire cast into it, to cast into whole wall or roof sections that can stand up and be placed into position after curing ??. Adding a layer of regular stucco to both sides should protect it from catching fire as well as give it much added strength.

Thanks for sharing!

Interesting idea. Do you know if it works?

It looks to me like this would be a good base layer under a concrete floor. Just pour the floor and skip the brick making part and then give it a top dressing later with standard cement. I have a lot of styrofoam around though so this looks like a good project to me

So many people commenting just from speculation would love to hear from people who has some knowledge on this subject, seen a couple of videos on styrofoam+cement and haven’t seen one that would melt from fire. Seems fire-resistant. Just worried about off gas but again many conventional-houses are full of harmful chemicals.

Add more potland and fiberglass chop strand for stength

"The kids complained; the motor doesn't" lmao 😂🤣🤣🤣

For making garden bricks, use old baking tins as a form. Saves throwing them away.

Hi, this is amazing! So when you say 'fluff' - us it complete powdered EPS or granular? Like pellets? If I want to make light weight planters, should I add any additional fibres to strengthen the mixture? Thank you!

How resistant is the brick towards fire, and how stable is it in acidic conditions?

If you contour your brick mold right, you could stack your bricks without mortar and still have some wind resistance. Making a half brick form would help. Think, LEGO bricks. How do they hold up to weight being applied to them? Have you tried forming other shapes like stock watering tanks or cisterns? Is this material suitable for that use?

Amazing 🙌

Another idea is to buy cases of toilet paper rolls on sale. Dip each roll in a concrete solution then stack them up by sliding over a vertical anchored rebar rod. You can fill the gap around the rebar by squirting in some urethane foam as you stack.

So the problem is that new companies seeing this are not about to go collect waste material and replace old buildings. They go out and get raw resources and expand out on new land. The pivot and focus point and legalities of such things should be that they are made from waste and collected scrap materials and applied to old structure to upgrade.

Super high tecnology😂😂😂. You funny bro

good thermal features

I have a new job making prefab panels for homes. Truck loads full of free styrofoam. Going to make some projects.

Thanks for sharing. Great recyclyling idea! Is it waterproof? if not, how could you make it so? Thanks

very useful idea to save on cement (for example) or produce lighter loads for carrying. I am curious as to how these would hold up in a fire, however?

Would you recommend using these bricks for building greenhouses in hot climate places to isolate external heat..? Will it be suitable..?

Does this really keep "ALL" of the sound in or out?

Thanks :)

Good idea to make a cool house, keeping out the sun heat. Is it as strong as a normal brick? If you have to buy that styrofoam beads, what is the cost compared to normal earth brick? Which is cheaper, at how much percent? Styrofoam pieces can be put on the ceiling to prevent heat from the sun.

First off, you'll never get a building inspector to sign off on something like this. No testing, certification, etc... And yes, in the event of a fire the polystyrene in these things will give off lots of really bad smoke/fumes. However, if it is covered in drywall, it would be just as safe as any other foam insulation.
