Interesting. I've made a quick search over Runet, it seems that basalt / basalt-plastic rebar is in large-scale production: http://nano-sk.ru/stekloplastikovaya-armatura/bazaltovaya/ http://nano-sk.ru/stekloplastikovaya-armatura/bazaltovaya/ They claim it's better and cheaper than steel rebar. No word about disadvantages, which I assume exist (edit: found, see below). Edit. Oh, they carry a price: http://nano-sk.ru/price-list/ http://nano-sk.ru/price-list/ -- 1m of d=14mm rebar costs ~$0.60. But I don't know the price for the regular steel rebar, though :) Edit2. There's a list of disadvantages here (sorry, in Russian): http://www.tdbazalt.com/category/materiali_dlia_stroitelstva_i_otdelki/armatura_stekloplastikovaya/nedostatki_stekloplastikovoi_armaturi_minusi/ http://www.tdbazalt.com/category/materiali_dlia_stroitelstva... 1. Can't stand high temperature, as basalt rebar has polymer as a binder for basalt fiber. 2. Can bend easier than steel; will break easier than steel 3. Can't stand alkaline environment (there're claims that some newer types of the basalt rebar don't carry this issue)
