My name is Dean Farago, I am a traditional plasterer/formworker/builder, trained by my grandfather, in methods of material manufacture and techniques of execution of design, passed down in the family since biblical time.
Just joined this forum, and came across this thread.
All the materials that are used my grandfather taught me ‘ we are just copying nature in making stone just speeding it up’
There are many materials on the ‘tree’ of mortars and these each have branches etc etc
And was taught to make each from scratch, and would love to pass these on as this will allow local production.
One of the most useful ones is what we call Charoset , the russians rediscovered it, and Prof Davidovits expanded his work on this even more. Calling it geopolymer, good name and all the kudos to him for rediscovering it, for me this was just how our family made concrete or stone always, O don’t ever use portland cement not only because it is an ecological nightmare, but it is just plain inferior in comparison.
It is probably one of the most versatile of all binders for over 7000 years, being able to make for eg a monolithic building that is limestone or marble, and does so by just creating the chemical reaction that the earth does over millions of years. It has been and allows for many many adapted applications, from everything to strong thin shelling using hemp fibres to a translucent stone or even being able to direct light for eg into a cellar or cistern.And if you are wondering how strong it can be, I have reached strength of over 200Mpa though this was the primo technique and mineral sources.
But its most popular use was in creating large ‘limestone’ structures, the pyramids of giza, pantheon in roma, and the pier that was mentioned, though these were done under duress of slavery, there are many other examples of structures that were done that people just assume was quarried stone or carved stone that were done using this methodology.
My main concentration over the past years have been refining the building techniques I was taught to meet all human physical needs as integral to the building in a permaculture frame of mind and to deal with post peak oil effects.
Water harvesting and keeping this water healthy and oxygenated, food production and hopefully with the help of others energy too.Each element in these needs helps the other. Everything from fireproof and insulating are just a given.And there is no waste,I was taught if there is waste then you know that you are doing it wrong. As alot of the materials needed can be found right under your feet in most cases it can be very local.
Have also been working on a solar calciner and have nearly perfected it, I was able to calcine 1.2 tonne of hydraulic lime for a job and used just 15kg of timber and palm fronds, when in the US I saw restoration lime people were pleased when they used 1 1/2 tonne of timber for 1 tonne of lime…I was horrified myself lol. Though this solar calciner isnt useful for mass plant work, it was never designed for that anyway, its just for local production.
You’ll have to excuse me for hijacking the thread, but I am a plaster fanatic and can go on about it till someone brings out a tazer.
