DIY REFRACTORY CEMENT!!!

Today we are making diy refractory cement based on a recipe I found on the internet! We will be using it in the next video to build forced air propane foundry, but until then, take care. Thanks for watching, see you guys next time!

I've been away for a little bit, but the 1000 sub special vid is coming soon! See you all next time :)

Before mixing perlite into your refractory mix try this add shampoo to the Pearl Light just enough very thinly coat after that and a small amount of Portland cement just enough to turn the pro light grey it's still B granule allow to dry add this to whatever refractory mix you would normally use you'll find use it much less water and have no need to cure it can be poured and used the same day without cracking or popping due to the water trapped in your perlite hope this helps

Thanks for sharing Neally! 😊🌎❤️💪

Thanks!

Danke für das tolle Video 👍. Sehr gut gezeigt !👍👍👍❤

[@quimblyjones9767]

Congrats on the 1k! Awesome work my man and good luck!

[@Neally]

Thanks a ton! :)

Number one mistake here is you were sifting the rock out of premix concrete. That premix also has sand in it which will make your mix off. Use (Portland cement) only together with your other ingredients and you will be fine. Also make a Woden mold not plastic. And make your fire brick a little thicker.

Thanks for the advice!

Man’s on creative mode 🔥

[@Neally]

Always, brother🙏

[@chkarron]

Always fun to watch 🥰

[@Neally]

Thank you

[@sareapo]

Ha ha, i love the experimentation! Looks like it still needs tweaking....

[@JonesCrimson]

That looks like a great recipe, much better than some of these other hoky shoddy mixes that won't make it to 2k Fahrenheit. Keep in mind, it will still experience heat shrinkage if you make a bunch of individual pieces and stack them together.

[@Neally]

I think the idea was in the right direction, but it definitely wasn't perfect. I might come back to it in the future and try to do better

[@odin0522]

good stuff

[@Neally]

Thanks!

[@DreidMusicalX]

Damn it, I just spent $40.00US on 6 brick. When I could have gotten all that perlite, cements and stuff all free.

[@aaronholcombe2963]

Ditch the sand and use magnesium oxide, replace some vermiculite with a phosphate. Magogo Crete has just as high of temp rating. But form a seriously strong bond fast. Vermiculite is not suitable to hold strength

[@backporchfoundryandforgeus900]

Ive tried these diy refractory cement recipes for like 20 different recipes. I’ve found no matter what it doesn’t hold up to high temps for copper and brass. It lasts a little longer for aluminum but eventually becomes too brittle and falls apart. The only thing that helped me hold it together was the high temp mortar i covered it with. Plus its a big heat sink. Kaowool is best for me.

[@backporchfoundryandforgeus900]

But if you cover the diy refractory cement with a 1” layer of kaowool then it holds up pretty good. But the weight can be the problem. I build furnaces and forges and my big 16” diameter by 16” tall furnace weighed almost 90 lbs with the diy cement. It weighs around 30 lbs now made of kaowool with an 1/8” covering of high temp mortar, and is much more efficient and heats up to temps much faster. But the diy refractory cements are cheaper of course.

New subscriber. Good stuff.

[@ryanpayne7707]

That's because Portland cement decomposes above about 500C into water vapor and calcium oxide. This is basic knowledge for anyone doing any forging and is why I don't take these videos seriously.

[@Tonisuperfly]

@@backporchfoundryandforgeus900great too thanks. I was looking for a lighter weight option. Makes sense!

[@jeremywarmack3994]

Once you get mix right you hafe to let it cure, Normal concert has set at least 3 days to a week it only 30% of strength. I am an ironworker. We can put shit up untell it cures. Without it, it is too brittle and not bonded. The metal columns will fall/rip out of the ground like a tree when the ground to wet and has bad roots. Cause can't hold the weight. No strength in the Concrete. It gets harder over time ( Old concrete is hard as fuck it is a B**** to drill into and chip 50+-year-old building will eat concrete bit way faster than new building trust me And ware out your arm) Soft test at a week look for hard ness, then let set for 30 days. This will help a lot.

[@mbahmannz]

Too dry . Need more water n cmen

[@godznutz]

I agree that it is too dry. You want your cement to be almost sloppy.

This shizz is the shizz

mommy sorry?

[@Neally]

papi?👀

Just how we like it👌

I love your enthusiasm, but you really should think about changing your video editing style. I really want to express that I am not trying to be mean, only to provide constructive feedback to help you better appeal to your audience. I feel you should consider abandoning most, if not all, of the quick pans and over the top sound effects. These are classic techniques for retaining the attention of an audience of children, since kids are easily distacted, but also easily entertained. This isn't a problem if your intended audience is children, but this is an instructional video that in no world should be attempted by a child. Children need constant stimulation because they are mostly looking only to entertained while adults who are actually trying to learn a skill are just looking for the best information they can find provided in a clear and concise way. These flashy editing techniques you use only serve to distract from the information presented and even may feel like condescension to some. Personally, I am under the impression that this editing style was intended as a way to express your personality, so it didn't bother me for that reason. But even for me, it was very difficult to focus on the information because all of the flashy camera pans and sound effects kept interfering with me taking in or retaining any knowledge. Again, I really love your enthusiasm in front of the camera. I also respect your attempts to make your video personal, and encourage you to continue to refine your camera presence and editing style. If you intend to make educational content for curious adults, I would strongly encourage you to consider what I've said about video editing. If you intend only to provide entertainment to any age group, then by all means disregard my suggestions. I promise they were meant only as constructive feedback and not intended as an insult. Keep it up
