摘　　要：铁相一般认为其组成为C4AF，属斜方晶系，常呈棱柱体和圆粒状晶体；铁相在传统硅酸盐水泥中仅占8％～12％，但在铁铝酸盐水泥中，铁相占15％～45％，无疑对水泥的性能起着非常重要的作用，其水化反应随A1／Fe比的增大而加快。Generally speaking, C4AF is the main components for iron phase, which belongs to rhombic system, often present with a prism body and round granular crystals ; in traditional portland cement iron phase only accounts for 8% ~ 12%, but in iron and aluminum acid salt in cement, iron phase accounts for 15% ~ 45%, which plays a very important role in properties of cement. With the increase of the A1/Fe ratio, its hydration reaction sped up.
