摘要：

Organic epoxy matrices have been widely used in the FRP reinforcing technique,but they have serious disadvantages of poor high-temperature resistance.An inorganic adhesive is invented to replace the organic adhesive.For the inorganic adhesive at normal temperature and different high temperatures,the microstructure and phase composition are investigated by means of X-ray diffraction(XRD) and SEM respectively.Results show that inorganic adhesive can resist at least 600 ℃ high temperature.Fire-resistance performance of inorganic adhesive can meet the requirements of fiber reinforced polymer(FRP) strengthened RC structures.
