About This Video:
I constructed a hut from fired clay bricks and mortared them along with a cement created from wooden ash left over from the firing course of. After I developed wooden ash cement years in the past in a earlier video, it was in response to the necessity of a cement created from materials apart from lime stone, which is absent in my location. Wooden ash was appropriate as a result of it incorporates calcium oxide, the lively cementitious materials for making mortar. I made clay bricks and fired them in a kiln made beforehand. Then I collected the wooden ash and made them into pellets storing them for later use. When it was time to make the mortar, I put the pellets within the kiln and fired them. Right here it is necessary to notice that the ash must be fired at a excessive temperature with oxygen, odd ash from a camp hearth will not work as is as a result of they do not get sizzling sufficient. It must be pelletized and fired once more in a kiln earlier than use. I combined the fired ash pellets with sand (1:3 ratio by quantity) and used it to mortar the bricks collectively. It is necessary to make use of a trowel (flat piece of wooden right here) as an alternative of naked arms to deal with the mortar on account of lye burning the pores and skin (I received gentle lye burns on my fingers). The ash left over from firing the bricks was sufficient to mortar those self same bricks collectively. The hut was 2×2 m and a pair of m excessive on the gables. Wood beams have been positioned onto the gables to kind the roof and secured in place with mortar. Then I made barrel roof tiles and lay them onto these beams. The entire undertaking took 6 and a half months to construct. The hut sheds rain effectively and the mortar is water proof (will not dissolve in water), surviving many rainstorms even earlier than the roof was up. The primary take away from this video is to all the time search for a approach to take a waste materials (wooden ash) and make it right into a useful resource (cement).

Primitive know-how is a passion the place you construct issues within the wild fully from scratch utilizing no trendy instruments or supplies. These are the strict guidelines: In order for you a hearth, use a hearth stick – An axe, choose up a stone and form it – A hut, construct one from bushes, mud, rocks and many others. The problem is seeing how far you possibly can go with out using trendy know-how. I don’t dwell within the wild, however get pleasure from constructing shelter, instruments, and extra, solely using pure supplies.
