The influence of CFRP sheets on the strength of short columns produced from normal strength concrete and fibre reinforced concrete

Abstrakt

This article presents the influence of carbon fibre reinforced polymer sheets (CFRP) on the strength of normal and fibre concrete columns determined in uniaxial compression. Fibre reinforced concrete (FRC) belongs to a special concrete group which is characterised by special properties without strength [12]. By using CFRP, we can modify the process of work of these composites, which are adhered to a prepared surface using a high performance resin, especially as is shown in this article. This composite material works in an elastic-plastic range with strengthening.
