中文摘要：

利用R·SAC作基体来制备光纤导光混凝土，采用抗硫酸盐侵蚀和抗碱溶液侵蚀试验、X射线衍射仪和环境扫描电镜分别研究了光纤导光混凝土的抗侵蚀性能、微观结构。结果表明：相同养护龄期下，与在自然水中养护相比，利用R·SAC制备的光纤导光混凝土在碱溶液中养护的抗折强度低很多，在盐溶液中养护的抗折强度则要高很多，而在盐溶液中养护的抗压强度略高，在碱溶液中养护的抗压强度则要低很多；利用R·SAC制备的光纤导光混凝土在碱溶液中养护后，其外观泛黄现象和腐蚀程度最为明显；利用R·SAC制备的光纤导光混凝土水化产物中存在团絮状C—S—H凝胶、针棒状钙矾石、柱状石膏、六方薄板状羟钙石和球状铝胶（即β-三水铝石），它们相互交织，结合比较致密。

英文摘要：

Optical fiber light conductive concrete was prepared with rapid - hardening sulphur aluminate cement （ R · SAC ） as the matrix.Anti - erosion property and microstructure of optical fiber light conductive concrete were investigated by means of sulfate attack resistance and alkali solution corrosion resistance tests, XRD and ESEM.Under the same curing age, compared with curing in natural water, flexural strength of optical fiber light conductive concrete with R. SAC in alkali solution is much lower, hut flexural strength of that in salt solution is much higher. Meanwhile, compressive strength in salt solution is slightly higher, but compressive strength in alkali solution is much lower. Optical fiber light conductive concrete with R. SAC curing in alkali solution, the appearance of yellowing phenomenon and the degree of corrosion is most obvious. Hydration products of optical fiber light conductive concrete with R. SAC have group C-S-H gel, needle stick ettringite, columnar gypsum, six - party laminated hydroxyl calcium stone and spherical aluminium glue, they are intertwined and combined with the relatively dense.
