Mineral-impregnated carbon fibre reinforcement for high temperature resistance of thin-walled concrete structures
https://orcid.org/0000-0003-4054-6414
Abstract For a wide application of carbon-reinforced concrete, the sufficiency of the bond between concrete matrix and reinforcing elements must be ensured, even at high temperatures such as in the case of fire. Mineral-impregnated carbon fibre reinforcement offers a promising alternative to conventional polymer-impregnated carbon yarns or bars, whose performance deteriorates markedly with increasing temperature. One of the challenges in the production of mineral-impregnated carbon fibre reinforcement is the selection of a processing technology and adequate raw materials. The work at hand addresses this challenge while focusing on the influence of the particle-size distribution of mineral fines on the impregnating behaviour of suspensions. Subsequently, the concentration shifts to the mechanical performance of thin reinforcement bars made of mineral-impregnated carbon fibre, as observed in three-point bending and pull-out tests. In comparison to polymer-impregnated reference materials, the new reinforcement demonstrates significantly enhanced mechanical properties at elevated temperatures of 100 °C and 200 °C.
