改性硫铝酸盐水泥

以适当成分的硫铝酸盐水泥熟料、规定掺量的铁选矿废渣（或粉煤灰）和适量石膏（或工业副产石 膏）磨细制成的水硬性胶凝材料。改性硫铝酸盐水泥分为改性快硬硫铝酸盐水泥、改性低碱度硫铝酸盐 水泥。

A hydraulic cementitious material produced by grinding clinker of sulfoaluminate cement with appropriate composition, a specified proportion of iron ore tailings (or fly ash), and an appropriate amount of gypsum (or industrial by-product gypsum) to a fine powder. Modified sulfoaluminate cement is classified into modified rapid-hardening sulfoaluminate cement and modified low-alkalinity sulfoaluminate cement.

改性快硬硫铝酸盐水泥 / Modified rapid-hardening sulphoaluminate cement

以适当成分的硫铝酸盐水泥熟料、规定掺量的铁选矿废渣（或粉煤灰）和适量石膏（或工业副产石 膏）磨细制成的具有高早强性能的水硬性胶凝材料。代号I—SAC。 注：铁选矿废渣（或粉煤灰）掺加量应不小于水泥质量的 15％，且不大于水泥质量的 35％ 。

A hydraulic cementitious material with high early strength, produced by grinding clinker of sulfoaluminate cement with appropriate composition, a specified proportion of iron ore tailings (or fly ash), and an appropriate amount of gypsum (or industrial by-product gypsum). Designation: I—SAC. Note: The addition amount of iron ore tailings (or fly ash) shall be not less than 15% and not more than 35% of the cement mass.

改性低碱度硫铝酸盐水泥 / Modified low-alkalinity sulfoaluminate cement

以适当成分的硫铝酸盐水泥熟料、规定掺量的铁选矿废渣（或粉煤灰）和适量石膏（或工业副产石 膏）磨细制成的具有碱度低、自由膨胀较小的水硬性胶凝材料。代号L—SAC1。 DB13/ T 1486—2011 2 注：铁选矿废渣（或粉煤灰）掺加量应不小于水泥质量的 15％，且不大于水泥质量的 35％ 。

A hydraulic cementitious material with low alkalinity and minimal free expansion, produced by grinding sulfoaluminate cement clinker of appropriate composition, a specified proportion of iron ore tailings (or fly ash), and an appropriate amount of gypsum (or industrial by-product gypsum). Code: L—SAC1. DB13/T 1486—2011 2 Note: The addition amount of iron ore tailings (or fly ash) shall be no less than 15% and no more than 35% of the cement mass.
