The article describes the results of research work on the reinforcement of concrete structures via carbon reinforcing filler with a cold curing resin. As an object of research were selected: brand of concrete M-350 and experimental cold curing carbon fiber based on an epoxy matrix. The physico-mechanical characteristics of carbon fiber are investigated. The properties of concrete samples externally reinforced with carbon fiber after conducting full-scale exposure in various conditions and without it are investigated. It was established, that strength gain of reinforced samples compared to purely concrete samples is up to 550%.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
