sounds good. I wonder a bit whether breathing aluminum would be a health concern. I'm guessing not, as it would be sort of inert. And nowhere near as bad as breathing wood smoke, I suppose. What do you think of some guy's idea of adding perlite to the cement? I'm no expert: I don't even know the difference between mortar and concrete at this point, but I'm getting there.

Ah-ha! ty!

@@user-hj7ld4ff7p Yes perlite could work as well, some fire bricks are made with it.

I had to chisel out refectory in the afterburner section of a burn furnace for melting x-ray film and lithographs to refine the silver out ( Gave me a tan)

​@@user-hj7ld4ff7p loose aluminum is definitely bad for you. Neurological problems associated with heavy metal poisoning. However LOOSE aluminum, not all aluminum. For a stove to work you need something thermally stable, there are all kinds of cements that can handle the heat but they're not super common because we don't work with exposed flames in our daily lives anymore. To keep this as simple as possible I would recommend 2 metal buckets/cans/barrels/chimneys/etc that you can nest together, the air gap will insulate. It'll be light as hell and get the job done

it comes back :/

This! Do Not Make fire enclosers from concrete. I'd wager these crack and or explode within a few uses.

I've used heaps of Thai barbecues like this. I have had a couple crack after many years of use but never heard of one 'exploding'.

If you notice...he is using just enough concrete to bind the main ingredient...dirt. Which is heat resistant as all get up.

good idea about the bucket handles. I'm wondering about whether the perlite would expand and contract and weaken the concrete. If not, it sounds great for making a lighter cement stove. I'm just starting my research. Next up is to google "refractory cement"

Fires quickly turn cement back into powdery slaked lime.

Where do you get perlite? How much to use?

"portable"

@@MC-tg1xkany gardening shop has perlite mate

Or the air pockets cause the surface to explode and put a concrete chip through someone's eye.

@@bkeepr4246 I don't think air pockets do that unless there is moisture trying to find it's way out.

I thought steel and cement had the same thermal expansion

Well this thread suks….I wanted to make one of these😞…but certainly not going to waste the effort if it’s not going to work. I have enough worthless chunks of concrete around my backyard

​@@permitfisherjust use refractory cement and no problem

😂,,, 😂😂😂😂

if its so to the point was mortar or concrete used?

how so and where?

@@stopwars8642 Towards the top, just enough below the rim for there top be time for some secondary combustion. If straight holes so do they need to be angled downwards at least 60 degrees, steeper the better to make sure air flows the right direction. More complex design can have winding channels that go down and link up with the main air inlet below. The benefits are that it both provides more heat and also gets rid of the smoke.

It might have been brick mortar.....no gravel filler in his mix. They make fire places in dwellings every day with brick mortar

That's horrible! As a chef we have a certain standard of kitchen and a dirty one outside is very scary! If i go here I might die from the food.

What a snobby thing to say to judge a person's way of life in another culture that is probably been living like that for thousands of years and the pansy ass chef culture that's worried about a dirty kitchen outside has only been in the last let's say 20 no I'm not disagreeing with you but you know if you're living like that for a lot of years you're not going to worried about a couple of germs

I cook most of the summer in my garden‘s „dirty kitchen“. It’s great cooking.

​@Cory_LaRose Yes, you definitely will. Probably best that you avoid BBQ so it's not from the food though.

Hahahahahaha

It's most likely, or should be refractory cement.

Yes.

I think, you could just put it back in the forming bucket.

put it back in the bucket that already has a handle

I'm not sure how easily it could be moved. Handles will help but I suspect it weighs quite a bit. Probably be better for a semi permeate location.

@@harveybc some potential difficulties with handles: top mount could interfere with pots side mount would put torsional stresses on the concrete that could fracture it. a plastic bucket with a GOOD handle (they do exist!) would be able to handle the weight.

A few concrete cinder blocks and 3 minutes, and you are building a fire.

Thanh you

Yeah because we don't have books anymore.

People used to listen to their Elders, and read books. It's not like nobody learned anything before youtube .... if anything, bad ideas spread faster on the internet than in the real world.

@@mikhalych9748 Books exist. They are just not as handy as your phone.

Have you seen the Rubik's Cube rocket stove on Cool Cement?

@@A2Z-Plants not yet, do you have a video for this ?

@@Tiny_Farm Yes.

I never expected a bear to be racist.

Me too.

They have about 12 videos on different stoves made with cement. I like the ideas, but I would definitely find a different mix so it'd be more heat resistant.

I certainly wouldn't recommend starting a fire and it immediately the water in the cement can expand and actually blow up the stove. 30 years in Masonry. And I'm just saying it needs to dry

Nice bhaiya

Doesn't take an expert to see how dangerous and wrong this is. This could explode injuring the user at anytime. It is not built for stove heat. If you are ignorant then just search high temp concrete vs regular concrete and dangers of regular concrete in high heat application

It’s way easier than freezing to death!!!!

Isn't this supposed to be a low cost solution and using PAM makes it expensive?

What is the supply list I can sure use the list now want and need a supply list so I can get started on mine please . Thank you ahead for letting us know

I was wondering the same. I think start small and work your way up slowly.

Give it a month to cure.

Mortar mix solid in 1 hr, cures in a day

An ounce of prevention is worth a pound of cure.

1 year ago, sorry, late question: I'm thinking about building this cement stove. Also thinking of adding perlite to make it lighter, though I suspect it might expand and contract and weaken the cement. Someone also mentioned using refractory cement as it's for kilns, but I do wonder about breathing aluminum. Comments? Thank-you. David Thor@@fullcircle4723

Will try this

this isnt concrete, its cement, concrete is when you add gravel to it, its the gravel which is explosive cos of the moisture that gets trapped around it, its not gonna kill anyone but could take an eye out

I would love to see someone make a video of concrete exploding from heat. But yeah this is not concrete Mr. Darwin.

@@JamieLaing1 Cement or concrete, doesn't matter. But you do you.

Johnnie Darwin?!? 🤔

It's just cement and sand mixed with water 💧

Can always make your own design because it's just the concept this video shows

@@stephenboyd4934 except not everyone watching will think to change the design. i think there’s another vid where there are feet and handles added. It needs something underneath like feet or a base to keep the heat off the floor, so that’s good too.

@@hansendesigns yes, have it lifted up & resting on a few bricks.

😊😊😊

Refractory cement, which is a mixture of Portland cement and lime, and sometimes it can include perlite to reduce weight.

indeed. another typical lifehack that can end up seriously injuring you

@@butstough yes and no. A small fire that is like... 1-2 pieces at a time, using proper A740 concrete would be fine. It's a giant heat sink, and will absorb the heat easily and evenly. But that initial fire was really hot and used a lot of softwood. Burns fast and kicks it's heat out quickly. Also, based on the the difference in color and sheer amount of water on the top of the mold when it is set, it didn't cure for long, which means that pan is likely to have suffered damage from the escaping moisture's causticity.

It looked like just rough sand and Portland, but I use perlite and bring my furnace up to copper melting temps. Doesn't fall apart or spall

@@tbishop4961 and how long did you let it cure in a mold then dry out of it before using it in a fire? Look at the water on top of the mold and color change at the end of the video . There is a ton of moisture in the concrete still, and that can have devastating effects if it turns into steam inside the concrete.

@@AgnotologyTV idk. Maybe 24 hr. I'm not terribly patient. I have a vid on my channel with my setup
