结合上文对空白样M0的分析，在水泥中同时掺加甲酸钙和多聚磷酸钠能延缓生成碳硫硅钙石，而不能阻止水泥石发生TSA破坏，M3抗TSA侵蚀的性能优于M4。罗忠涛认为[15]，磷酸酯能抑制或延缓水泥水化产物CSH的结晶及钙矾石的生成，使得水泥石的水化程度不高，早期强度较低。多聚磷酸钠加入到水泥中起到缓凝的作用，水泥石结构松散孔隙较多，即使加入早强剂甲酸钙也不能有效改善水泥石的表面结构，有害离子的侵入导致侵蚀破坏的发生。M4中多聚磷酸钠的含量较M3多，因此水泥石表层密实度不高，抗腐蚀性能差。
 
3 结 论
 ①水泥石中同时掺加甲酸钙和硝酸钡可以有效的抑制碳硫硅钙石的生成，其效果跟外加剂掺量有关。掺0.5%甲酸钙+1.0%硝酸钡的水泥石抗硫酸盐侵蚀的性能优于掺0.5%甲酸钙+0.5%硝酸钡的水泥石。
 ②在水泥中同时掺加甲酸钙和多聚磷酸钠能延缓生成碳硫硅钙石，不能阻止水泥石发生TSA破坏，掺0.5%甲酸钙+0.5%多聚磷酸钠的水泥石抗TSA腐蚀的性能较好。
