摘　　要：对地聚物和普通硅酸盐水泥的抗硫酸盐侵蚀性能进行了试验研究,通过研究地聚物的抗硫酸盐侵蚀机理,采用干湿循环法,对侵蚀后的产物进行了X射线衍射分析,结果表明:在5%的硫酸钠溶液中,地聚物砂浆主要是由于硫酸钠浸入试块孔隙中盐结晶体积膨胀而破坏。The paper tests the geopolymer and common portland cement resisting sulfate attacking performance. Through studying the geopolymer resisting sulfate attacking performance, it carries on X-ray scattering analysis for the materials corroded with wet-dry cycling method. The result shows that：in the 5% of sodium sulfate, geopolymer is damaged owing to the salt crystallization volume expansion for the sodium sulfate immersed into the testing members’ holes.
