Architecture：Age of Wood Ash Cement

I just watched it and I think it may be easy to operate in OHOL game, yeh, we need more wood and tree.

Primitive Technology: Wood Ash Cement

Here are the explains：
"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."

"chemist here. Spot on. The calcium hydroxide reacts with the CO2 in the air, giving calcium carbonate.
Careful with both calcium oxide and calcium hydroxide, they are very aggressive, on the eyes in particular.
Also, be careful on the oxide to hydroxide reaction. It produces a lot of heat and can boil the water quickly, spraying everywhere,"

Funny, I had just watched this vid before looking on forums.

i think this would pair nicely with industrialization, since sand doesnt exist
otherwise i'm fine because this makes for much more easily attainable materials to build walls and stuff

so basically i'm assuming this is how it'll be

Knife/Flint Chip + Any Tree = Tree Bark
Tree Bark + Kiln with Kindling = Kiln with Kindling and Tree Bark
Firebrand + Kiln with Kindling and Tree Bark = Firing Ash Kiln
Firing Ash Kiln + 30 Sec. = Ash Kiln
Clay Bowl + Ash Kiln = Bowl of Wood Ash
Bowl of Wood Ash + Bowl of Water = Bowl of Ash Mix + Clay Bowl
Bowl of Ash Mix + Flat Rock = Wet Ash Pellet + Bowl of Ash Mix 3/4 (and then this keeps going until it's empty)
Wet Ash Pellet in Wooden Tongs + Firing Forge = Hot Ash Pellet in Wooden Tongs
Hot Ash Pellet in Wooden Tongs + Bowl of Water = Bowl of Boiling Pre-Cement Mix
Bowl of Boiling Pre-Cement Mix + 10 Sec. = Bowl of Pre-Cement Mix
---
Clay + Smithing Hammer = Wet Clay Brick
Wet Clay Brick in Wooden Tongs + Firing Kiln = Terracotta Brick in Wooden Tongs
Stone + Terracotta Brick on Flat Rock = Terracotta Dust on Flat Rock
---
Bowl of Terracotta Dust + Bowl of Pre-Cement Mix = Bowl of Cement Mix
Bowl of Cement Mix + Flat Rock = Flat Rock with Cement Lump + Bowl of Cement Mix 1/2 (and one more use until normal clay bowl)
Bare Hand + Flat Rock with Cement Lump = Flat Rock with Wet Cement Brick
Bowl of Terracotta Dust + Flat Rock with Wet Cement Brick = Cement Brick
---
A number of cement bricks can be made to create a wall and corner

Well done!

The cement brick was proof of concept that it didn't dissolve in water, and that the cement is really supposed to be used as mortar.

"Use: I think this material might have a potential use as a mortar holding rocks or bricks together in wet environments where limestone or snail shells are unavailable for making cement." - Primitive Technology

+1 for bricks and mortar!

We do have limestone for plaster... I wonder what the "concept" extended tech tree looks like?

Thanks for the great post
