测试了掺入不同量的高钙粉煤灰、高 fCaO熟料、钢渣及石膏的试样抗蚀系数、质量增量和强度，结果表明，掺高 fCaO物料的水泥抗硫酸盐性与引入的 fCaO量、浸渍的硫酸盐种类和浓度有关，掺高 fCaO熟料和钢渣的水泥抗硫酸盐性优于掺高钙粉煤灰的水泥，适量石膏的掺入可改善试样的抗硫酸盐性，在实际应用中可通过控制引入的 fCaO量和掺入适量石膏来提高掺高 fCaO物料的水泥抗硫酸盐性。
測試瞭摻入不同量的高鈣粉煤灰、高 fCaO熟料、鋼渣及石膏的試樣抗蝕繫數、質量增量和彊度，結果錶明，摻高 fCaO物料的水泥抗硫痠鹽性與引入的 fCaO量、浸漬的硫痠鹽種類和濃度有關，摻高 fCaO熟料和鋼渣的水泥抗硫痠鹽性優于摻高鈣粉煤灰的水泥，適量石膏的摻入可改善試樣的抗硫痠鹽性，在實際應用中可通過控製引入的 fCaO量和摻入適量石膏來提高摻高 fCaO物料的水泥抗硫痠鹽性。

Parameters as corrosion resistance ratio, the increment in quantity and strength of cement with different addition of high calcium pfa, high fCaO clinker, steel slag and gypsum were tested. The results indicate that the property of sulfate resistance of cement is associated with the amount of fCaO and the type and concentration of sulfate in the corrosive agent. The addition of high fCaO clinker and steel slag in cement possesses higher performance in the sulfate resistance compared with the addition of pfa. The introduction of proper quantity of gypsum can improve the sulfate resistance property. This property can be improved in practice through the proper introduction of fCaO and gypsum.
