Primitive Technology: Wood Ash Cement

I think I have the chemistry right. If any chemists are watching correct me if I'm wrong. The calcium compounds are converted to calcium oxide in the second firing, turn to calcium hydroxide in the water and then set to calcium carbonate in the air. There maybe a pozzolanic effect due to the alumina and silica in the ash too. The end product is a cube made only from wood ash (fired twice) and crushed pottery. It sets hard after 3 days and will not dissolve in water even when fully submerged for 24 hours. Thanks.

Whatcha got for a refractory cement? Something that can handle forging heat? 2,000°F or a bit more.

This method was mentioned in the Holy Quran 1400 years ago

Are you making calcium or potassium hydroxide?

How i obtain the oragen thing in nature?

STEP 1: Burn as much dry debree of the hardest wood possible in firepit over 1000 degrees
STEP 2: Mix ash with water to make ash bricks or ash balls
STEP 3: Place Ash Bricks or balls into hot fire over 1000 degrees
STEP 4: Place Deep Clay Bricks from ground into hot fire over 1000 degrees to make clay hard bricks
STEP 5: crush both fired clay bricks and fired ash brucks/balls and mix then together while slowly adding water until you make a solid stone like brick and let dry for 3 days
STEP 6: Place Stone like Brick into 1000 dgree fire again to harden even more
STEP 7: Place fired stone brick ( fired clay and fired ash combined ) into water and make sure it does not fall apart. Success if it does not. Now you can use it for making house 😊

Can you use linestone instead of
Eggshells/clamshells/snailhousings?

You need a gooood quantity to even use this cement/roman concrete to wven built a stone wall


So it would be good to know a easier source

Hola te puedo enseñar algo más fácil

Parabéns seu canal é o unico desse tipo que mostra as coisas como eram a seculos atraz .e sem falcatruas

Работал несколько часов чтобы хватило пепла на маленький камушек, сколько же древесины нужно сжечь чтобы дом построить? А крепость? Пирамиду?

Thanks for good informations and no advertises or "donation boxes" ... 🙂

نحن في الباديه على مر العصور نصنع أرضية موقد النار من الرماد بخلطه مع الماء وعندما يجف نشعل النار به

Burning wood only for the Ash, no sane person would do that.

You've so much improved on the air blower! Practice makes art!

I guess that I can call this math!

Thanks so much for your video , but I will like you to be mentioning the name of your ingredients

When you see how easy everything is, you see the sicknesses in our societies.

Boa noite estou aprendendo fazer panela de

A GREAT REVOLUTION , VEGETAL CONCRETE !!!

What are the ingredients??

Awesome 👍

Thank you for being simple and to the point

What kind of tock are you crushing??

It'd be cool to see you make some sort of clay brick/cement pathways to connect some of your main areas you traverse/ areas you live

Makasih udah berbagi vidio yang bagus

You need 30 million sub's for this❤❤❤❤!

What is this, can you clarify

Geopolymer concrete is the term you are looking for i believe, take that historians who didn’t read exodus.

Flyash(potassium bicarbonate) + previously fired termite clay pots= paperweight

KHCO3

Need an art teacher much? The term you are looking for geopolymer concrete. You’re welcome

Nah man, terracotta or previously fired clay, potassium bicarbonate from the fly ash. KNOH^2

sehr, sehr aufwendig...

Good creative 👍

How to remove simant h from wall and siling,,,?

If some day i end up stranded in an island i hope to remember your videos. lol.

Roman cement awesome

Faut faut

From now an I will assume cavemen used chopsticks

Can we get some words on the screen or even better talking. Just to make what you’re doing a bit clearer

So questions:
1. How many parts ashes to how many parts terracotta powder?
2. Can brick powder also be used?
2.5. If so would it be better replacing the terracotta or be with it?

He is right I am from Pakistan and when I see 👀 British architect here they used Wood ashes in walls etc so finally I sure that it is really work

This guy is tough as nails!

This is amazing
