Abstract

Mineral-impregnated carbon-fiber (MCF) composites are for the construction industry a promising alternative to steel reinforcement or conventional fiber-reinforced polymer (FRP) composites due to their high mechanical performance over a wide temperature range, corrosion resistance, and high technological flexibility. For an efficient industrial fabrication of MCF, a long-range processing window need to be secured for the reactive impregnation suspensions. In this regard geopolymers offer great potential since - similar to organic thermosettings - they require thermal curing to accelerate polymerization, enabling quickly high early strengths.
