Abstract : In this exploratory program, the UV-initiated cure of small test samples (2 inches by 2 inches by 3/4 inch) of a furan resin concrete was demonstrated. However, due to the high cost of the UV initiator (diphenyliodonium hexafluoroarsenate), the amount of initiator required to obtain complete cure results in a very high-cost polymer concrete. Three approaches -- reducing the amount of initiator, use of a catalyst, and use of alternate, more reactive initiators -- for reducing the cost of the UV-initiated furan concrete were investigated. None of these approaches, all of which would effectively reduce cost through reducing the amount of required initiator, yielded a completely cured furan concrete upon UV exposure. (Author)
