Carbon-reinforced concrete
Reinforcement structures with high temperature stability
An insufficient fire resistance of the composite material has so far inhibited a broad application of carbon-reinforced concrete. The reinforcement elements available at present are composite materials made of carbon fibers with a high number of filaments, which are embedded in a polymer matrix. The polymeric impregnation materials ensure the bond between the individual filaments and the concrete matrix. However, the inserted polymers soften under the effect of heat, and the carbon-reinforced concrete can no long resist the acting mechanical loads.
A promising approach is the development of...
