Strengthening Concrete Building Structure via Reinforcement External System From Carbon Plastic

Abstract

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%.
