Yeah-— I know.. the recent “successes” of crappy rebar construction techniques.
The info on carbo-crete... carbon fiber reinforced prestressed concrete is quite impressive 100x or more flexsion and tensile strength than any other concrete slabe or post.
Check the link i posted to carbocrete— and there is lot’s more on the net of course. Imagine- instead of the “hardyboard” on sidings or structural elements-— that carbon fiber concrete slabs used. Last for centuries— many more than the Cathedral’s timbers, and... they cannot burn.
I don’t think the materials you are talking about fit historical restoration. As for the Russians and construction expertise, especially in timber construction google Transfiguration Church to start with. 150 ft high and standing strong since 1714. Built in place of identical structure burned by the lightning and standing for centuries before. Not a single nail was used to erect it. There is a national park near Archangelsk in Russia with a collection of ancient timber buildings moved there from all around Russian northwest. If you know a thing about carpeting the sophistication of these structures would amaze you especially in light of how old they are.
