It was mixed with crushed terracotta as an aggregate and formed into a cube. The cement set hard after 3 days and did not dissolve in water after this period. Process: First I burnt bark and leaves in a kiln at high temperatures to produce well burnt, mostly white wood ash. The ash was then mixed into water and stirred well. The excess water was poured off and the resulting paste was made into pellets and allowed to dry. A pellet was then re-heated in the forge until it glowed about orange hot. This was then taken out, cooled and dropped in a pot of water. The pellet dissolved and boiled due to a chemical reaction with the water. The paste was stirred and crushed terracotta (old tiles from previous projects) was added and mixed to form a mouldable mortar. This was formed into a cube and allowed to set for three days (in the video, a cube made exactly the same way 3 days previously was used due to time constraints). The resultant cube was strong and made a slight ringing sound when tapped with a finger nail. It was placed in water for 24 hours to simulate a very heavy rain event and did not dissolve or release residues into the water. My current theory: The main component of wood ash consists of calcium in some form (e.g. calcium carbonate, calcium oxide). This can be up to 45% from my research. Calcium is in higher concentration in the bark and leaves of a tree. When the ash is mixed with water, the soluble component of wood ash (10% pot ash) dissolves into the water. But seeing that it does nothing for the cementing process, it is drained off leaving the insoluble calcium (and other components) in the paste. Doing this probably raises the relative percentage of calcium in the paste to about 50% or more. Most of the other 50 % consists of silica and alumina which are pozzolans, materials that chemically react with calcium hydroxide to increase the durability of the cement product. The paste was then made into a pellet and fired again to high temperature to convert all the calcium compounds to calcium oxide. It also reduces any charcoal in the pellet to ash if it hadn’t already been burnt the first time. This step seemed important as un-fired ash pellets only partially hardened and would fall apart in water, though retaining a weak undissolved 5mm thick crust. I can only surmise that re-firing the ash just gave a greater conversion of the calcium components to calcium oxide. The pellet is slaked in water converting the calcium oxide to calcium hydroxide. This cement was mixed with crushed terracotta which may also help in some way that I’m not aware of as I only did this one experiment and did not test other aggregates yet (e.g. sand, gravel etc.). Terracotta is porous and might hold together better than other materials. The mixture is allowed to set in air where carbon dioxide reacts with calcium hydroxide to form calcium carbonate cementing the aggregate together. After this, the cement will not dissolve in water. 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. Wood ash is a pretty ubiquitous material to most natural environments inhabited by people using biomass fuels. Wood ash cement turns a waste product into a valuable building material. From my research, wood ash is already being used as a partial replacement for cement in the building industry without decreases in strength of the final product. But I’ve only just started experimenting with it and don’t know its full capabilities and limitations. Calcium content of wood ash differs depending on the species of tree, the part of the tree burnt and the soil it’s grown on. Cautious experimentation is still required before committing to a hut built from this material.

Hello everyone Today i'm show you about how to Build five - story mud house with swimming pool and build hut around swimming pool (full video) +Amazing video 1 - Evolution Primitive Time : Build Mini Underground Swimming Pool(https://www.youtube.com/watch?v=xvyq64np0O0&t=63s) 2- Evolution Primitive Time : Build wooden house underground(https://www.youtube.com/watch?v=-Quw2l4SGwo&t=31s) 3- Build An Underground House ( Look Like Hobbit House)(https://www.youtube.com/watch?v=6Fpsr45Mma0) 4- Building Medium Fish Pond(https://www.youtube.com/watch?v=eI9QkCVJnYM&t=53s)

Rescue Abandoned Puppies Building Mud House Dog And Fish Pond For Red Fish. In my place have a lots of puppies abandoned every where, so i decide to collect and rescue dogs 4 and make a small conformable mud house with water fall fill mini swimming pool and playground yard in front of house for these poor puppies. This video i build the fish pond around mud dog house and raising some red fish with water wheel. I hope you all enjoy with this video, thank you please subscribe and ring icon to get more new videos update.

In this video I would like to show you guys about the new update on the last awesome underground house. This is the unique and most creative idea to build such a great underground swimming pool ever. I still dig the soil to build this amazing construction. There was an unbelievable situation that I never met before. While my friend and I was digging the soil, we saw a really big python in a huge hole with a lot of eggs. Suddenly, my friend and I decide to let her free and we forgot that she remained many eggs inside the hole. Actually, we try to find that big python and give her the eggs, but we can’t. So we decide to cook and eat those eggs in order to survive. After that we got more power to continue our hard work to dig the underground swimming pool. We got a lot of questions from the views and other friends, but one of those is “How can we maintain the water in the soil like that? It must leak.” That is a very common question. We got our own technique to do it. We need to find the termite house in the forest to mix with the red soil to make it more sticky. And then we use it to cover the bottom of the pool. It’s such a hard work for us because it took almost three weeks to finish this project. If you got any question, please do not hesitate to leave a comment below. We’re happy to answer all your questions.
