This paper probed deep into a high-temperature resistant inorganic matrix: alkali-activated slag cement (AASC), which is a kind of cementitious material prepared by alkali-activator and pozzolanic or latent hydraulic material. Firstly, the mix ratio of the AASC was optimized to improve the wettability and mechanical properties. Then, the effects of the adhesive matrix and the type of fiber-reinforced polymer (FRP) were observed through FRP-to-concrete bond tests on 93 specimens. The test results, coupled with anchorage analysis, indicate that the AASC has comparable reinforcing effects as those of organic epoxy matrix; the anchorage length of FRP sheets has a significant influence on the failure behavior and failure mode of FRP-enhanced concrete structures. In addition, our tests prove that the AASC has favorable high-temperature resistance and bonding effects. The research results provide a good reference for the design and application of inorganic matrix for FRP-enhancement of concrete structures.

本文深入探讨了耐高温无机基质：碱活化矿渣水泥（AASC），它是一种由碱活化剂和火山灰或潜在水硬性材料制备的胶凝材料。首先，优化AASC的混合比以改善润湿性和机械性能。然后，通过对93个样品进行FRP到混凝土的粘结测试，观察了粘合剂基质和纤维增强聚合物（FRP）类型的影响。测试结果以及锚固分析表明，AASC具有与有机环氧基质相当的增强效果。FRP板的锚固长度对FRP增强混凝土结构的破坏行为和破坏模式有重要影响。此外，我们的测试证明，AASC具有良好的耐高温性和粘接效果。研究结果为无机基体在混凝土结构玻璃纤维增​​强中的设计和应用提供了很好的参考。
